I have stock manual locking hubs. Mud and water passing the seals are only part of my concern.

 

Don't bother opening the diff cover. Nothing in there, shaft just floats. Are you sure you have both the inner and outer collars along with the lock washer installed? Parts Mike did sell a washer with their spindle nut kits but a quick search didn't come up with anything

 

Spindle nuts, lock washer are all there and torqued to spec. They hold the wheel on the spindle a far as I can see, not the axle shaft. The only thing in the hub that stops horizontal movement for the axle shaft itself is the snap ring that holds the locking hub in place. As for the diff, I was kinda thinking that, but wasn't sure.

 

Interesting that you have a BJ 60 with the axle snap rings, my 93 axle, and none of the newer ones I've had apart even have the stub machined for it. If the stub is moving and you have the snap rings, you may well need a shim in there. I've seen later D50 TTB's with them in there from the factory... Mind you the 96-97 stuff puts the snap ring and shim on the spindle side of the lockout...

 

I have a 96-97 BJ60 with the machined snap ring groove at the start of the splines of the stub shaft. I believe that is what you just stated though (82f100swb)

 

full circle snap rings are usually found on aftermarket axle shafts at the yoke where the ujoint meets the ear.

The machined groove at the end of the stubs on the splines kinda hold the hub in.

 

I was looking at a much newer truck and there is a snap ring on the axle shaft with thrust washers. But not mine. I did get mine from a chassis cab and as I understand it, there were D60's on them a couple more years than on reg. chassis. Still don't think that would make any significant difference with this problem. Sorry, I was looking back through my posts and may not have stated it well. There isn't a snap ring on the axle shaft itself, it's on the housing holding the locking hub in place. Also, just wanted to appologize if I came off a little short in some previous posts. Had a really rough week (hospital visits, etc).

 

Mine doesn't have snap rings at all, the axles I have seen with the snap ring at the start of the splines have been D50 TTB's.
Fullcrews axle is like mine, just the outer snap ring for the lockout, nothing on the shaft itself.

 

I was looking at some more exploded diagrams and they do show a groove and snap ring on the axle stub..... What years did that occur on???? I may just have to pull the hub again and have another look....
