I've just bought a yellow '73, which I purchased in Fresno, CA, a ~240
mile drive from here. It has 62k miles, runs well, and only ran me
$3700
The suspension tends to leak down when parked, the headliner is
hanging down because at one point the coach had mice, and the original
furnishings forward of the galley are gone, with what appears to be a
flexsteel jackknife couch on the passenger side, and a folding table I
already had on the other.

I've replaced the fuel pump on the 4k onan, and now it runs pretty
well, though the throttle feathers once it's warmed up. I've replaced
the exhaust system from the downpipes aft, as the original was in poor
shape. I've not yet rubbed out the paint.

As the PO told me, the house water pump is no good, so i'll be
replacing that, and the ductwork for the furnace through the back of
the electrical compartment, which the mice got at. (only one chewed
wire, near as I can tell. 120v romax running through the ceiling from
the closet side to the bath side)

I have it over at Bob's Wheel Alignment (
http://bobswheelalignment.com/ ) , waiting for him to get parts costs
from his suppliers. He tells me the lower ball joints are shot (and
showed me what he meant with a ball joint off a Tacoma. Ball no longer
retained in its cup), and the uppers are marginal. Needless to say, I
feel I dodged a bullet taking the CA-99 and I-5 home and not having a
wheel fold under, but now I fear attempting to drive it. Additionally,
the boots on the CV joints are torn, and one of them ran dry.

My first question is, are the halfshafts sold by O'Reilly as '73 Toro
shafts the right ones?
( http://www.oreillyauto.com/site/c/search/CV+Half+Shaft+!s!+Axle+Shaft/01424/C0362.oap?model=Toronado&vi=5143751&year=1973&make=Oldsmobile
)

And how about the ball joints?
( http://www.oreillyauto.com/site/c/search/Ball+Joint+&+Components/C0317/C0106.oap?model=Toronado&vi=5143751&year=1973&make=Oldsmobile
)
(I figure I'll go with the Moogs)

What sorts of pitfalls might I run into, that I haven't already?

And, anyone have any idea which model it would have been? yellow
exterior, (used to have) an orange stripe, orange carpet (only pieces
left of this are under the norcold fridge and in the closet)

I love this thing already, even though I've only had it a couple
weeks. I intend to keep it going for a long time, and, at 23 years
old, I've got the energy to make good on that.

Sir: O`Reillys sells 2 styles one is new and will not work, the remanufactured will work if they have the tripod inner axle. You will have to remove the joints and put them on the GMC axles.

Or you can just call Jim K at Applied GMC and get everything you need, the right parts, the first time. Not to mention he can and will give you free advice. I just ordered the complete urethane bushing kit from him...less than $120.

Oh, yeah. Welcome to the cult.

Patrick,

Kerry's advice is spot on. Applied GMC (Jim Kanamota) will provide you with the parts you need, right the first time (usually, with the possible exception of a small shipping mix up now and then) at competitive prices.

http://www.appliedgmc.com/level.itml/icOid/677

Bookmark this site. You will use it a LOT.

The other really good asset to those of us that own these things is Jim Bounds at Cooperative Motor Works, in Orlando.

http://www.gmccoop.com/

There are others as well, and if one of the Jims can't help, they will direct you to whomever can.

Welcome to the group. May you enjoy your new coach as much as my wife and I do.

Patrick,

The first thing I will say is -

Welcome to the Group/Family/Cult/Asylum.

You need to put Applied GMC in your phone list.

You should also sign up with GMCMI, because when you will get a parts interchange book so you can try to get parts locally. But, if it important, talk to JimK (Applied), he has the parts that work the first time.

You are undoubtedly the youngest GMC owner I know of. As you are the third new owner today, I hope you have read my notes and advice to the other two. I will, however, still include the same greeting based on the relation you will soon develop with the coach and the community. It is taken from my world as a waterman as I think the relation is not just like another toy, but much more. So,

May the Good Lord bless this coach and all those that set forth within her.

Welcome Patrick

Matt

Patrick,

Welcome aboard. I hope you're not too sensitive, 'cause some of us old
codgers here are sure to (ENVIOUSLY) call you a "young whippersnapper" or
something similar. It's GREAT that you're taking on a GMC at your age. I
can hardly wait to see and hear the tale of your progress.

My advice, after 14+ years of GMC ownership (making me only middle-aged),
is to not rush into anything major. For example, yur immediate trip to the
front end shop, while an apparently judicious decision, may prove to be
less than satisfactory. The GMC front end LOOKS familiar to any front-end
mechanic. But there are a lot of surprises lurking there. Like those ball
joints -- they're NOT standard Toronado. You definitely need the GMCMI
parts interchange list, and the assistance of GMC-experienced shops, AND,
you need to study this document:
http://thedovetailjoint.squarespace.com/storage/GMC%20alignment%20R-0.6.pdf
or
http://goo.gl/ui8Zq

You're going to learn there, among other things, that GMC wheel alignment
is such an iterative process that to get a good alignment, you'll have to
have a very good close personal relationship with the alignment shop owner,
or very deep pockets.

Beyond that, there are other front end issues, such as the front wheel
bearings which can become a part of the alignment problem, including the
cost. IF you're faced with problems in that area, it can quickly become
more economical to replace most of the front suspension with more modern,
heavy duty, more easily serviced components (which we refer to here as the
"1-ton front end").

There are similar lessons to be learned about many facets of the GMC.
Someone here's been through every one of them and will share their
experience and hard-earned knowledge if you ask before you leap.

Well, let's see.

Thanks for all the welcomes!

Yes, the one in Fresno listed for 3900 linked by rcjordan is indeed
the one, though the listed price went into effect while I was driving
to Fresno, so I didn't see it until after I'd bought it. it was listed
at 4000 last i'd seen before driving

I actually have a GMC parts book from 1973, and a complete shop
manual. Forgot to mention that the PO included them. (he'd gotten
them, and it, from its first owner two years before)

at this point, front end wise, i'm trying to make it safe, as in,
'will respond predictably and not risk major failure when making
ordinary maneuvers' as opposed to making it nice. I'm not exactly
independently wealthy; while I can drop a few $k more into it without
going into the red, i'd be eating up my financial cushion.

I'm also trying to do this quickly. Neither Bob nor I want it sitting
in his shop waiting for the delivery to arrive from Applied GMC,
unless they can match the speeds O'reilly can.

At some point i'll probably go whole hog, with the 1-ton front end,
and the quadrabag system, Alcoas, and a bunch of other goodies.
Probably some of that will happen at the end of this semester of
community college classes. but /during/ the semester, I just want to
know the wheels aren't going to fall off. (Bob does suspect one of the
wheel bearings might be on its way out, but said it 'could also just
be the nut')


I hadn't seen several of those documents yet, and I'll be sure to take a look.


Oh, by the way. What sort of interest would there be in a scanned copy
of the service manual, put up online? It seems a shame to keep it to
myself.

Greetings from another Angeleno! What part of L.A. are you in?

Totally agree on joining GMCMI - the parts exchange and newsletter archive are worth the price of admission.

Your coach is gorgeous and as I'm sure you've discovered already, smog-exempt. Very Happy

Please feel free to join us on the Facebook group too - the link is in my signature.

Welcome aboard from another relative noob!

Patrick,

A word to the wise - I GA RON TEE that there is NO ONE at your local O'Reilly's that knows ANYTHING about a 1973 GMC or the parts it
requires.

Sure, it uses a lot of parts that are the same as the Toronado, HOWEVER, there are differences!

The front wheel bearings are one of those differences. The clearance for the Motorhome bearings is not the same as the car bearings.

DO NOT use any other bearings other than Timken Set 23 with a spacer marked with 0.0095 which is the correct clearance for a GMC.

There are also problems with the front and rear wheel bearing seals and you need to know which brand and part number to use.

The lower ball joints fall in the same group.

Bottom line: ask the GMC brain trust for the correct part numbers or buy them from a reputable GMC parts dealer that KNOWS what
they’re doing.

I'm sure your local O'Reilly's will deliver the parts faster but after you install them and they fail you'll have to wait to get the
right parts plus do the job over.

It’s kind of you to offer a scanned copy of the manual, however, here's a link to just about all the pubs you'll need for your GMC:

Patrick,

The GMCMI "parts exchange" booklet is not the same as parts book from 1973. Many part numbers have changed and quite a few parts are not being made. People have found the correct part numbers or substitute parts. It is updated periodically. (Your 1973 parts book is not.)

With the age of our coaches and how long you plan of keeping it, you'd be better off fixing the first time for the long term. If you need ball-joints, bearings and other front end parts.... you might as well go with the one-ton from Manny. (Or JimK for a "upgraded" package.) Between that and the steering linkages, the front end will be good for 10 (and maybe 20 to 30) years.

If you are going to be keeping this for years and years... Try and make a rule... no quick fixes. Fix it right the first time.

You'll save money, time and frustration in the long term.

OBTW: Welcome aboard. It is good to see owners younger than the coach. It means the coaches have a future.

Can someone elaborate on what Mr. Boyd was saying about the
halfshafts? for the life of me, I can't see a difference between
these, except that the O'Reilly one has a larger boot on the outer
joint.

http://appliedgmc.com/prod.itml/icOid/662

So far, I've been figuring to get the esoteric parts from Applied GMC,
and get the more standard ones from O'Reilly, while double checking
with you guys on which ones to go for. We'll see where that gets me!

Patrick,

If you get an axle that looks EXACTLY like the one in your O'Reilly link,
you can use it by removing the joints from each end of it and installing
them on the axle shaft from your OEM assembly. There are photo albums at
gmcmhphotos showing how to do that.

BUT, perhaps 50%-75% of the time, when you order that axle you'll get one
that is not exactly the same. More and more, what we receive are axles
that have newly designed joints with different splines on the shaft, making
them incompatible with the GMC shafts, which are longer.

You might as well tell O'Reilly's up front that if what they receive is
different than shown in that photo, send 'em back for replacements --
repeatedly if necessary.

Ken H.

G'day,

PLEASE correct me if I'm wrong but wasn't it reported that a number of these so called "remanufactured" axles were crap?

Regards,

Patrick,

If you get an axle that looks EXACTLY like the one in your O'Reilly link,
you can use it by removing the joints from each end of it and installing
them on the axle shaft from your OEM assembly. There are photo albums at
gmcmhphotos showing how to do that.

BUT, perhaps 50%-75% of the time, when you order that axle you'll get one
that is not exactly the same. More and more, what we receive are axles
that have newly designed joints with different splines on the shaft, making
them incompatible with the GMC shafts, which are longer.

You might as well tell O'Reilly's up front that if what they receive is
different than shown in that photo, send 'em back for replacements --
repeatedly if necessary.

Ken H.

What Ken is point out is that your GMC axles shafts are longer than the Toro axles and you can use new CV assemblies from both ends.

This picture start the photo album on axle rebuild.

Enjoy and welcome.

I guess I've been lucky: The ones I've gotten through O'Reilly and Advance
have been good. I still move them all around, feeling for roughness and
looseness, before I disassemble them. Never hesitate to return a
suspicious one because they are precision devices that subjected to large
loads. The fact that they're being replaced with recently manufactured
(and probably less robust) incompatible joints probably indicates that
usable cores of the original design & manufacture are disappearing. It's
cheaper for them to manufacture replacement shafts than it would be to
replicate the original joints. But the GMC population isn't large enough
to justify manufacturing shafts to our length requirement.

Sir: in this pic you will see 2 different axles offered, a new one with a round inner joint and a rebuilt with a tri-pod type inner axle. The round type have a different spline count and will not work on the GMC axles.
http://www.oreillyauto.com/site/c/search/CV+Half+Shaft+!s!+Axle+Shaft/01424/C0362.oap?model=Toronado&vi=5143751&year=1973&make=Oldsmobile
You will have to remove the cvs and put them on your GMC axles and reband the boots. I recommend not banding the inside on the outer cv. It will allow the boot to flex and It will not leak.
http://www.gmcmhphotos.com/photos/crestmont/p35381-2-year-old-boot-amp.html
To swap, remove the outer cv bootbands and slide the boot back, remove the c clip and pull off. The inside boot is tricky so I do not remove it. Remove the small band and hold the inner joint up as you drop it on the outer joint end. It will push the inside cover off the inner joint so you can remove the snapring, remove the tri-ball without dropping or taking apart, remove the inner snap ring and slide the housing off with the boot intact.

So far, I've been figuring to get the esoteric parts from Applied GMC,
and get the more standard ones from O'Reilly, while double checking
with you guys on which ones to go for. We'll see where that gets me!
