I agree with the above posts, you don't need any special Kent Moore tools to set up new bearings. Just a few photos to show what I do.

Hey guys I had one fail on me the other day. Can I take some hubs pull them apart pack them and put them back (with new seals) and keep on my way or do I sill have to check play? I dot have the tools to check end play just a press at work. Hijack a little sorry.

Cole, the variation is in the stacked height of the spacer, shims and bearings (and the hub/housing itself). It will not be identical for any two sets of bearings so you have to check. You could get lucky, but my experience is that you always have to re-shim, but I have only done six of these. Quickest way is to have Ken do one for you so you don't have to do it again soon when the bearings wear quickly from riding on the end of the "cone".

Dave, most would say a $200 snap on dial indicator is a "special tool"! Nice clean bench and parts...

You have to be methodical and precise do this right. As always, understanding specifically what you are trying to achieve will allow you to get there by various paths. The first two are the hardest...the second one I did I had to re-shim after torquing final assembly to get it right...easy after that lesson.

Cole-you're not 'hijacking' with your related question,so keep posting..if yours 'failed' by locking up tho,bearing replacement is needed and the play Should be checked; if you can pull the yoke off,and the 'housing',check the races in there for damage..I've finished and mounted the left for Ron's car yesterday,will do the right (and put the 66 yoke on my 'used' one) today..the outer bearing is the same as the LM front INNER FYI

here's my setup stuff; I had the spindle areas turned down on a friend's lathe so the bearings just slip on,and filed the yoke splines to also slip-fit (took me 3 days for them!)..I use the housing with races in that I'm going to use,and put MORE spacer-ring to check the end-play..to get the yoke off,an impact gun (air or HarbFr electric) works,but you may want to put the wheel flange in a spare rim and tire to hold it,,and PROTECT THE SPINDLE THREADS when pulling the yoke off..BTW, I found a .124" shim,which got the end play back in-spec..

The only special set up you need is a honed out inner bearing. With that you lessen the chance of having machining tolerances stack up on you. To loose is better than to tight.

It really is best to use the parts you will be assembling with the exception of the bearing that was honed out so it will slip onto the stub shaft. It is best to use a new bearing but if you use an excellent used bearing add .001 or .0005 to the tolerances.

I always set up to the smaller tolerances but not the smallest tollerance if I can help it. Don't be afraid to grind a little on a shim if you can make it square.

Thanks for the info. The hub is toast, its final drive to get my home sounded like someone put gravel in my tire. Jacked it up did the ol slop test and the tire flopped around like it wasnt even bolted on. I am lucky it didnt just lock down on me and throw me into traffic. I am pulling a set of rear hubs off a junk car this week and was planning to just repack and seal them using the same bearing assuming it would all be the same. I threw a used hub on my car for now until I could rebuild the set.

There's nothing wrong with regreasing a good used bearing. The catch is the need for the unusual tools needed to pull the yoke off safely, and to remove and reinstall the pressed-in-place stub axle.

As for Ken's comment about a honed-out inner bearing: I prefer to use an undersize (spare) stub axle. The bearing is one of the main variables in the stack while an undersize stub axle has no effect on the stack, so the setup used for measurement (including the actual inner bearing) is the final setup used in the hub.

Whatever approach is used, if the final measured endplay is in spec, you're good to go.

1st is the spacer/shim I used for setup;next is my setup with Ron's housing w/ new races pressed in,clamped in the vise and dial ind on to read end play (pull/pushing the housing)..I'm going between .058" and .082" travel which is...umm..umm-- .024", so I'll select the shim as required (after I get the curious cockatiel off my head..)

so yes Cole-you probably can 'do your own' BUT you'll have to get some tools and scrounge for on-hand items as needed..1st pic is the yoke from above cleaned,rust reformered and on the used one going on my 67 right side; measured it as .006"..2nd pic is Ron's left,down to .0015" with his shim assortment..this will take some time tho,mine have been taken apart over the past 2 yrs,cleaned at former work,rust removed by acid-dip taking a few days then 'coating', before re-assembling over a week or so..

A buddy with a lathe cut down an old spindle for me to do a slip fit. Works great.

I have to add that Steve Goodman was very generous with his advice and a big help when I did my axles. He suggested shimming to 0.002-0.003" for maximum bearing life.

As others said - you MUST torque to specification to get an accurate end play reading. NOTE: The large collar varies from one axle to the next - pretty crude and I've even seen a few that were not cut square. Each axle must be shimmed to get the correct end play. It's a time consuming task to get the end play correct.

Just curious ... who is the authority on rebuilding these. I know several do rebuild them and heck i have done a few sets myself but who truly has the most experience and expertise in this area? Best of the best?

That's a subjective question. Everyone has their preferred re-builder.
My vote would be for Steve Goodman at [www.rearenginespecialists.com]

Steve is very generous with his help on this forum and has a good reputation. As previously stated Steve helped me with solid advice so I could do my own. He has the experience to do them correctly and folks who have sent axle units to him have reported they're units came back properly re-built.

--X3 !,but there are others like Clarks, LeVeque,Ken Hand and Claypool around the country that have the tools and experience to set them right..if you don't have them and the time/patience (youth helps),you have to 'bite the bullet' and have them done in a timely manner..I'll probably do a few for my own,but not for someone else,although my setup *maybe* loaned locally..BTW,I put metric studs in my used one,and Ron's already had 1/2-20 in his; I used the 14" s10 wheel in my sig pic to hold and torque the yoke nut,and wimped out using an electric HarbFr impact gun..

Here is a question for anyone who has used the J tool. J – 21836 that is.

I am having a problem where when I fully assembled the tool as the shop manual indicates, the bearings are not coming together enough to seat on to the races that are in the hub/housing. I can move the entire assembly, the tool and bearings as one, inside the housing back-and-forth probably 1/16th of an inch.

I took it back apart and got a good look at it. The tool itself has a positive stop for the inner bearing. So that made me look at the outer bearing end. When I stand the hub up and remove the knurled nut from the outer bearing ( leaving the bearing in place) it looks like the tool runs out of threads before the bearing seats fully into the race. I presume the face of the nut should push the outer bearing as far as it needs to to seat into the race. When the tool shaft runs out of threads (at the smooth section of the tool) the bearing is still about 1/16 of an inch or so from contacting the race. I have tried this on two different hubs.

Anyone else see this before? I don't need to use this tool, it was lent to me and I thought it would be fun to figure out. I was simply using a dial indicator on the bench previously. I can go back to that, but I'd sure like to see what I'm doing wrong with this tool.

I have pictures I can post later when I get to a computer.

I used an old outer bearing as a spacer right behind the knurled nut so I wouldn't run out of threads. Now the bearings seat onto the races just as in the shop manual drawing above (which is not in my '65 manual, suppose it was added to a later update maybe).

These are both new bearings, all I can figure is that there is some tolerance difference with the new bearings on width of part that presses onto the shaft?

Anyhow, I am getting .0325, closer to .033". If I add that to .097", I get .130"

I have .127 and .133 shims as well as a couple of .005.

I'm gonna guess that .133 is the right choice so it is a little on the looser side prior to torquing the axle flange on? I can use a .127 + .005 shim set and Be at .132" I would then be within 2 thou instead of 3.

What end play is this tool designed to leave you with? Is it right in the middle of the window of acceptance, or on the loose or tight side perhaps?

Suggestions?

Here are the Shop manual instructions. Don't know if they will be helpful.

Select the shim thickness, using Tool as follows:
a. Remove the knurled nut from each end of Gauge(J-21836).
b. Position spindle inner bearing on small end of gauge-.small end of bearing toward pin on gauge- then finger tighten knurled nut against bearing.
c. Position gauge and bearing assembly through, the inboard side of spindle support.
d. install bearing spacer over large end of gauge, then position spindle outer bearing on gauge and against spacer fig. 15. Install under cut end of knurled nut against bearing and hand tighten nut so that there is no play in the gauge body.
e. Install dial indicator (J-8001) and position indicator finger against moveable shaft of J-21836.
f. Move shaft of J-21836 so that it travels the maximum permissible distance limited by spacer and inner bearing.
g. Record reading obtained in step f--recheck to ensure accuracy.
h. To be reading obtained in Step f, add 0.097’. The total obtained is the required shim thickness necessary to maintain specified end play.

EXAMPLE: Dial indicator reading obtained in Step f: 0.026

Add 0.007’’ to dial indicator reading 0.007

(Gauge J-21836 is constructed to represent the smallest shim, which is 0.007’’.)
Shim thickness required (TOTAL): 0.123

Shim to be installed would be 0.124’’ thick since this is the shim with a thickness nearer to the value as computed above.

4. Disassemble gauge and install spindle outer bearing. Pack both wheel bearings with a high-melting point wheel bearing lubricant prior to installation.
