Wheel won't spin after Knuckle Rebuild when hub locked (1 Viewer)

[petescoffee]

This is on a disc break front end.

So The drivers side went back together fine. Lock the hub and I can turn (rotate) the wheel.

Onto the passenger side: reassemble knuckle, install wheel bearings, install the hub in the free position and the wheel spins fine.
Lock the hub and then I can not turn the wheel. Will not rotate. Don't want to force it. Un lock the hub spins fine.
Took the hub back off, took the hub apart and put it back together. spins fine in free put in lock positions and it Still won't turn (rotate). The hub is a Aisin hub.

Back ground- Worked fine before disassembly. Took a part because had a loose wheel bearing and went ahead took all the way apart and installed new knuckle bearings and reassembled. Everything went back together fine, at least I thought so. Now I am stumped.

Any ideas?

Thanks,
Dave

It sounds like your birfield is pinched in the knuckle housing. Try running an 8mm bolt down the center of the stub until it bottoms out and see if you can get the birf to spin that way.

Note: this could also be a sign that there is too much preload on the knuckle bearings.

Hi
It sounds like your axle assembly is not rotating when your hub is locked in.
The CV joint could be binding on the axle housing.
Did you install the spring clip back on to the axle ? And did the clip locate correctly into the grove on to the axle shaft?
I use an 8 mm bolt screwed into the end of the axle then pull the bolt and axle forward when installing this clip?
After fitting this spring clip to the axle shaft can you turn the axle?
Hope this helps.
Cheers .

Or - the inner axle isn't fully engaged in the third member.

Thanks,
I'll check these items out.

So I took the hub off and put a bolt in and the birfield spins fine. Put hub on with out the dial and the birf is hard to spin.
So I took apart the knuckle again reinstalled everything, check to make sure the new wheel bearings are seated and they where.
Birfield spins (using 8mm bolt in end) without the hub, but not with the hub on (this is with out the dial even on). Hub seems to be binding up on the birfield. Strange. Side note the hub is hard to put on once it gets to the dowel pins. I need to tap it on. Did not notice this as an issue when I took it apart or when I put the other side together.
Any thoughts? Cone washers not aligning the hub?

I'd say if the shaft spins with the hub off and no spin with hub on the differential end of the shaft isn't going in far enough - or something is wrong with the birfield or hub internals . Check the brass insert inside the hub to make sure it's seated , maybe put some light paint or magic marker on those parts and see what is interfering .

WAG here Dave. Put the tire back on while the locking hub is off, spin it a few times and recheck the wheel bearing preload.

When you assembled the axle are you sure the snap ring got fully seated?

If not then the end of the axle may be pushing against other parts and not allowing it to turn when fully assembled. Just thinking out loud.

Where did the Birf come from maybe it is a 76-78 long Birf and getting jammed in the later Aisin
Hub. Jut another thought

Thanks for all of the replies.
I took it a part again and started from scratch and redid the measuring with the Toyota SST for Centering the knuckle. My overall shim dimension was correct but my Top shim amount and lower shim amount were reversed. installer error for sure. Shimming to much in 1 direction was binding the birfield.
Thanks for the assistance.

cool thanks for the update

Glad you were able to sort out the problem.

I have a similar issue, but the axle spins with the hub on, without the front cap. but when I put the hub locker on, it doesn’t spin. Any ideas?

Axle not fully seated?

Using a snap ring when an end button is required will do that.

I got super busy the last 2 days, but I’ll update you guys and look over this stuff tomorrow.
