Hi everyone,
Nick and the guys at Applied have that noise in my front left figured
out. It's the wallace bearing on that side. When the load get's light,
the bearings get loose and the wheel moves a bit.
I'm not ready to buy new front hubs, bearings, knuckles etc. What can I
do to re-hab these wallaces for a bit longer? Can I shim them or something?
Are there any gurus on these around? I don't have a lot or experience
with bearings since my Street Stock days on the dirt track and that was
just to keep repacking the camaro pronts since we'd hit each other so
hard. It's also possible that my brain is loose from that.

I took my knuckles to Cinnabar and had them replace all the bearing including the Wallace third bearing. Even after 100K miles from the PO, they really did not need to be replaced. Not cheap but cheaper then all new. They also replaced the lugs with longer ones and new rotors since mine were out of spec. Think it was about $900.00. But now I know I am good for another 100K if I grease regularly.
Good Luck

OK, just remember I am new at this also. Attached is a link to the Wallace picture flyer that I got with my coach. My homework showed that the knuckle was machined to accept the new third bearing. Now you have three bearings, the two original and the bigger wallace third bearing. You can not remove the wallace bearing and go back to stock with your knuckles. You would need to get new knuckles or just replace all the bearings like I did. I elected to take the easy way out and let Cinnabar do the work because I can not work to the right of the decimal point to install new bearing myself. My mechanical aptitude makes me stay to the left and therefore I keep myself out of trouble.
Here is the link to the picture.

Cinnabar part numbers:
Item: 1235 Front Wheel Bearing Kit. $106 times two
Item: 6012 Bearing, Wallace (3rd) $75 time two
I also paid the labor of $320 to assemble
I have a few more pages I can scan but this one has the most information.
Hope this helps.

... I'm likely to change it back over when I can afford to do it all
but that's not exactly in my reach right now.

Anytime you (or any GMC'er) are thinking of doing MAJOR work on your hubs/knuckles/brakes/a-arms, you should look at the compare the costs with the "Bill Hubler Heavy Duty Front End Kit"
<http://www.appliedgmc.com/prod.itml/icOid/635>
If you add up ALL the components upgraded by the kit, it costs more to STAY OEM than it does to upgrade.
Granted, if you do not need, and are not planning a "close to full rebuild," it could be cheaper to stay oem on just the few parts you need.

Some one that does not understand the front hub assy. loosened up the big
nut thinking it should be set like any wheel bearing.
The hub is shot from not having the assy tight.
Now the knuckles are shot, along with the hub.
I know you can run it that way till you hear grinding sound, then it's over.
No core value for non rebuild able parts.
I was one of the first to purchase the Wallace Hubs back in 1984.
Wes C. told me that I must be one stupid engineer to think that it would do
anything to straighten the front . I had to agree, buy I told him it was a
good way to get the grease fitting.

i would think it would be OK to just replace the one side for now and do the other one when it goes bad. sounds like the knuckle is shot from what Jim says.

Is that for both sides or  one side...

The "Hubler Kit" would be something to think about if you needed more than just knuckles. The kit replaces (and upgrades) your hubs, knuckles (including bearings and seals), lower A arms (with ball joints and bushings), Drive axles (with CV joints), and brake rotors/calipers. The kit also includes spacers.
If your coach needs over half of the above items, you really need to run the numbers before replacing with OEM.
Note: I do NOT have the kit. My plans are to rebuild one of my coaches as a "keeper" coach. (Using the other coach while I do it.) As I plan on driving the "keeper" 25 or 30 years from now, I will be installing a Hubler kit along with upper arms and all the tie rods and levers.

I looked at the Hubler Kit, but it's quite a luxury at that price.
Maybe someone who has one can tell us how that's going. They say that
the bearings are off-the-shelf but are they easier to replace than the
stock ones or do you still need the special tool?
I plan to own my coach for a while, so I've got to start saving up for
the fuel-cell engine I'll need when we've finished burning all of the
dinosaurs! The strategy so far has been; get it all working right
first, then think about the upgrades. I've got a list.
My prediction is that the Hubler 1-ton kit is just about double the cost
of the stock parts I need now (partly because it also upgrades the
brakes, axles, etc.) The problem with my Wallace kit is that that all
of the involved parts I have are modified, so I can't expect to get the
core charge back. I think I'll just look around the shop here and
finally sell some radios I've been meaning to. Two-ways anyone? I've
got a lot!

> Could you give us a ballpark as to costs?
For what I need (I already had a couple of the parts I needed) I'm
looking at around $1700.00 in parts. The Hubler kit lists for $2995.00.
I think I'll do it someday, but after I'm done setting back to stock I
should be good for 50,000 miles, so that should get me a year or two! :)
I got a solid piece of advice when while we were shopping for our
coach. We had a chance meeting with Rick Flanigan. His GMC is a
beauty. He really did a nice job and it left me wondering how we'd ever
get a coach that nice until he told me that he'd had it for 18 years and
you just do it a little bit at a time. Even my wife bought into that
philosophy.
So it look like this is the little bit we'll do now, but I'd still like
to hear about how the Hublers are working for people. If the bearings
are easier to swap in the future that definitely makes a difference, but
I'm speaking from the perspective of someone with a coach that has a
different "upgrade mod" and is trying to get it put back since the
support for it went away.

Since the Hublers include a brake upgrade that makes them
more attractive, of course.
My brakes have never been impressive so someday...

Sir: another option would be to call Dave Lenzi and see if He would repair Your Wallace setup. I believe it is a good set up when torqued properly and would be an asset for you in the long run..
