Could someone please respond with the part # and source for front wheel bearings?
Also, tips and tricks for installing them.

this is a big deal,
there are 2 ways to never have to do the bearings again,
one way is "the zerk"
http://gmcmotorhome.info/front.html#ZERK
and the other way is "the one ton version II"
http://gmcmotorhome.info/front.html#hubler
both will give you 100,000 mile bearings
something to consider

Rick,
As I see it, you have four choices, and as much as you seem to like to do things yourself (not altogether bad), you may want to think about all these options.
1 - You can buy (order) the parts locally, the bearings are Tinken set 23, the seals are National 5123 and 5109, but you still need the special puller to get the thing apart and the risk of damage is high even with the right tools.
2 - Buy the parts and borrow the special tools to do the job from JimK. This comes with a native guide. When you find the parts you will realize that JimK’s margin is not very much.
3 - Buy the 1-ton front end kit and put it in. I will collect your old hubs if you don't want to store them.
4 - Call Dave Lenzi. He is about an hundred miles from you. Make a plan to take your hubs there and see if he can re-build them his way. If he can (requires that they not be seriously damaged from other’s repairs). Then have him do it his way.
I was one in the crowd that watched Dave “field strip” a hub at DuQuoin. He was working more slowly than I suspect he normally does so we could see what he was doing. That was good. He quietly explained where problems occur and why a prior repair had rendered this hub unsalvageable (by his methods). I might do that just to have the time to talk to Dave.

Let me tell you how good Dave L. is. Those were my hubs he pulled apart. As he was crankin on the rachet to "pull" the bearings he stated " I think they've been sleeved", which means he wont't reuse them. They were too tight. Which means more resistance on the puller(and they were sleeved). And he could tell. ,,,,but if it were me,,,Hubler 1ton. (I did),,,,,,PL

Paul, I am with you. Dave is as good as they come on the old frontends. I would do nothing to mine without being in touch with Dave. Of course now I have the one ton so I am hoping it runs a long time. We had zerks in the old one, placed where Dave said. I shot 2 squirts in them twice in 30,000 miles. When the guys pulled them at Jim K's they told me they were tight, just like they were when we put them in. I am a believer in those zerk fittings for the old front ends.

Matt,
I am going to add a caveat to steps 1 & 2. Disassemble the hubs and knuckles
and inspect first.
Here's the catch there aren't any specs in the Maintenance Manual. I
contacted Dave Lenzi and he sent me the specs; unfortunately I can't seem to
find them now.
Gene Fisher has some here that Charles Wersal got from Cinnabar:

After I inspected the hubs and knuckles off The Blue Streak I went to step
4.

Bill,
I've never heard of anyone having a problem with Ken Thoma's rebuilt
KNUCKLES (we don't really have any spindles unless you count the stub
axle). While you need to talk to Dave Lenzi for a true answer, I
suspect his only objection to them is that they're not compatible with
the method he uses to repair knuckles: they've been turned out too
far, to accept the sleeves, that he can't have them metal sprayed back
to the required dimension.
I would not hesitate to use the knuckles you have. Be sure to install
the Zerks.

I once bought hubs and knuckles from Ken Thoma. After returning from about a 1000 mile trip, I decided to check the air in the tires. When i pushed on the right front one it moved a lot. I jacked it up and the wheel basically fell off. Upon removing the axle nut I found that the short shaft on the spindle had broken off in a jagged edge from the center of the hub.
I called Ken and he sent me another one. I asked him what may have caused it and he said: "when they quench a pallet of these the first ones get the hottest oil and sometimes they harden too much. The middle of the pallet are usually just right and the end of the pallet sometimes are not hardened enough". I asked him to please send me one from the center of the pallet!
I had no more problems with them and they are still in today.

Use a good moly grease. Valvoline SynPower is my choice. I called Dave for his approval before greasing mine and he said "Do it".

On the parts I got back from Ken Thoma, it looks like he sleeved both hubs and possibly only one of the knuckles. I am not concerned about the knuckles since there is plenty of meat left around the outside of the bearings. I will definitely drill them for the grease fittings.
The hubs are a bit more worrisome. The sleeves are 2" OD x 1.85 ID so I calculated the bending strength is 79% and stiffness is 73% of the original hubs. Wish I had known about the metal spraying fix before I went this way. However, at the pace I have been working I may die of old age before I get this unit back on the road.
|
Sir: be careful when drilling a knuckle that has been sleeved. The Knuckle is cast iron and the sleeve is steel. If you use a hardened machinist drill bit it might break off when the metal changes fron cast to steel. I would suggest using a standard drill bit and drill slow and easy and keep lubricated.

Bill,
I can see how you'd do the calculation of changes resulting from the
removed metal. How did you accommodate the replaced metal in those
calculations? I don't have the experience to know how one includes
that.
