Rear Hub/Bearing Carrier

[DougPulver@aol.com]

Help! I am installing some of Roger's very cool rear axle lip seal nuts. Right side went well (after replacing all the studs which some PO had rethreaded to coarse). Left side not going well at all. The bearing carrier (BC) and the hub marry up perfectly on the bench. As the hub nut is tightened I have checked the hub/axle fit. All goes well for a while but progressively the BC and the hub won't seat until they are apart by about 1/4 inch. I've tried (1) taking the BC back off and reseating it (2) rotating the studs of the BC to the holes in the hub and (3) using the old nut. All to no avail. The speedi-sleeve on the back of the hub certainly seems to have clearance and passes through the lip seal. Since all this worked fine before I took it apart and since I didn't replace anything except the rear oil seal and the paper seal between the BC and the hub (which so far isn't necessary) it seems like it should all go back together. What am I missing? Or what should I try next? I would prefer not going to GOF West in 2 weeks on 3 wheels. Thanks.

Gene, Good thought. With the bearing hub NOT in place, the axle slides in completely. With the bearing hub partially tightened down by the nut, the axle slides in completely. Only when the nut is tightened almost all the way down does it then not go all the way in. At one point I thought maybe the bearing was put in slightly off, so I have been offering it up gently (rather than knocking it on) and then securing it by tightening the nut figuring that it would apply the most even pressure. Good thing I decided to be an accountant of sorts. If I had to do this for a living I surely would have starved to death long ago.

Doug, This is an obvious question, so pardon. Are you sure that, during removal, the bearing itself did not become displaced? I do like Gene's theory. When I replaced my hubs with the nut/seal solution, I had to drift the brass slinger bushes further into the axle shaft in order to get everything to fit up properly. _Peter

hi Doug - do you mean that the hub & shaft won't get closer than 1/4" from the carrier? this is about the length of the plain part of the studs, so the hub could be getting stuck on them. the sleeve is unlikely to be the problem, if it is all the way down the shaft, cos inside the hub is nearly an inch of clearance, and the sleeves are just over 1/2" long. also check the shaft splines for burrs, they sometimes get distorted as they are a loose fit in the diff gears and move about a bit. ocTagonally TCRoger

Roger, Thanks for your suggestion. The gap between the hub and the bearing carrier is about 1/2 the depth of the "plain part of the stud" which I guess is a bit less than 1/4". I don't think the lip-sealed nut is involved since the old nut now causes the same problem. (Of course, I also don't understand why I'm having this problem at all because apart from adding the sleeve and applying the new nut, nothing else has changed from when it all was removed.) All this leads me to suspect that there may be some problem between the sleeve and the Archimedes bushing. I installed the sleeve all the way up against the back of the hub and had no problem on the right side. Again, all these parts marry up nicely on the bench. Anyway, I have a friend/English car mechanic (from Bristol) who said he would come over Sunday morning to help me figure it out. I'll let you know what the solution turns out to be. Thanks to you and all the others for offering suggestions and most of all support. I'm not a mechanic and really have no particular mechanical skills (you may have noticed this from previous emails). I just so love these cars that I'm willing to suffer some humiliation by asking what no doubt often appear to be stupid questions. Have a nice weekend and thanks again.

Don, Thanks for the suggestion, but with the bearing carrier removed, the axle shaft and hub slide all the way in, no problem. Wierd.

Doug, Out of curiosity, try putting the other (opposite side) axle/hub in on the troublesome side. If it seats up then the problem is with the first axle/hub somewhere. Try that one in the other side and see if it hangs up then. Be sure to mark the two hubs to make sure they end up on the correct sides after all testing is done. I know it involves undoing the good side that you are done with but it would tell you where to look then. Compare left and right side axle/hub set-ups to see what is different. And let me know if you need me to come over and have a look see. I don't have any major plans this July 4th weekend so can work it in I am sure. And happy Canada Day to those celebrating that.

Thanks to all of you who offered suggestions and read patiently of my dilemma with reseating the hub to the bearing carrier on the left side of TC 5850. Turns out it was operator error - kind of. I initially removed the axle by tapping on the backside of the winged knock-off. Upon removal, I noticed that the axle was not inserted into the hub as far as the axle on the other side of the car. In fact, when the sleeve was offered up to cover the spines (on the inside of the hub) some of the axle splines still protruded. I asked two very knowledgable TC people if that were a problem and they correctly said that if it came out that way and was working prior to removal it should be fine. My mistake was two fold. First, I incorrectly thought that the hub was pressed (with some pressure) on to the axle so it didn't occur to me that it might move - not true. Secondly, given my original suspicion, I should have measured the distance to the differential to double check. But given my first mistaken belief, I never tried that. Apparently what happened was on removal I moved the hub outward about 1/4 inch. Once I used JB Weld to secure the sleeve on the inside, the hub would no longer move and so I was stuck with an immovable gap. Heat works wonders and allowed me to remove the sleeve without damage. Then I tapped the axle back into place, reinstalled the sleeve and reassembled everything else. I greatly appreciate this group for all the help I have received. Many, I suspect most, of us are not mechanics by trade and therefore can learn quite a bit from the experiences of the group. I certainly have.
