Hey guys trying to finish my disc swap on my 14 bolt. What are the torque specs. I serched but could'nt find it. Sorry. I can't fin the torque specs for the spindle lock nuts. Also, when I took it apart there was no key in the hub and the nut were finger tight. Good thing I am doing this. Do I have to have the little key in there? Thanks guys. I need to get this done today! Thanks for your help.

I messed up big time somewhere. I put in new bearings and seals in the hubs. When I put it on and spun the hub I can see it is not true. When it spins, it is cockeyed or wobbles. Hard to explain in words. Could it be the races. Are they in there at an angle? ****,hope I just did'nt ruin the $90.00. Bearings and races.
 
Sounds like you don't have the race(s) seated properly (installed crooked or not fully seated). When you changed the outer race did you make sure that AFTER you installed the retaining clip that you pressed the race back down against the clip (this is where alot of people mess up).

About the spindle nut torque spec, you torque the nut to 50 ft/lbs while rotating the hub then back it off and then torque it again to 35 ft/lbs and then install the key and retaining clip. If the slot in the nut doesn't line up with the keyway in the spindle I always tighten the nut to line them up.
 
I thought about that and wasent sure. Thank you 4X4HIGH. I was talking with a member here (bradshawtech) . He told me you were the man who knew it all when it comes to these trucks. Thanks again.

Drive cup beyond the snap ring groove.
Install snap ring in groove.
Drive cup back against snap ring.

No problem.

I do know ALOT about these trucks and many other vehicles for that matter. I've been wrenching for 32 years so a person tends to learn alot after that many years. :D Hell, i've probably forgot more than some will ever learn. :haha:

Ok, I got the race back down against the retaining clip. I put the hub on and it spits true now. But it is really hard to spin. Does,nt want to spin. I had to pound the hub off with a rubber mallet. The outer bearing seems to be frozen up. Should I take off the new seal and pull out the bearing and check it out? Thanks. This is a PITA.
 
It should not be that tight. You should be able to slide the hub assembly onto or off the spindle with no problems. Take it back off and make sure you did not accidently hit the ID of the inner bearing race leaving a burr that is getting caught on the spindle.
 
I put my finger in there and could not find a bur. When its not in the race I can spin the bearing. When its in the race it won't spin. Thanks 4X4HIGH. I'm glad you online!!
 
Sounds like you might have bent the cage of the bearing when you pressed the outer race back down against the snap ring.
 
Its the same on both hubs. So, pull the new seal pull out the bearing and start over. Gotcha. Thanks.
 
6]Ok Scott, hope you can help on this one. I seated the outer race against the lock ring. So I pull out the lock ring and put in the good bearing. Once I try to put the lock ring back in it won't go in. The bearing sticks out past the race a little bit. When I try to put the lock ring in it hits the cage of the bearing. There is not enough room. It is Timken number SET38. I could hardly sleep last night, could,nt get this off my mind. Thanks Scott.[/QUOTE]

Sounds like you put the bearings in upside down. Here is how they are installed....first the bearing gets put in place with the small taper side facing the snap ring groove, then the bearing race goes in with the taper facing the bearing (away from the snap ring groove), then you install the snap ring, next you flip the hub assembly over and drive the race back against the snap ring.

If this doesn't make sense to you then i'll draw you a picture and post it here.
 
Crap, now that makes since. Damm, all that work has to be redone. Thanks Scott. I am going to send you some beer,steaks,girls, whatever you want! Do I have to pull out the inner race first before I can pull and flip the outer race? I think so. Thanks Scott.

I can't remember if the outer race will fit through the inner race but it would just be easier to remove the inner race.
 
I pulled everything. Starting from scratch. I have been waiting and hoping you would be online today! You are the man:bow::bow::bow: I owe you big time. Thanks. Hope thid id the last time I do this today. This mistake only cost me two seals. So far.

Those seals aren't cheap though.
 
That worked perfect. So I don't mess up the inner, what is the correct way it goes in?thanks.

Inner race goes in with the taper facing you then the bearing sits in the race then the seal goes in.
 
Omg. It spins so easy on the axle. Wow. Thanks Scott. Couldn't have done it without you. One down, one to go. Off to the parts store for new seals, again. Thanks.:bow::bow::bow:
