Stub axle binding on bearing housing - more shims ?

[danielzink]

Not quite sure what's going on here.

I got some new trailing arms and decided to rebuild the entire assembly.

I got everything together and put a rotor on and started tightening the castle nut just a little and everything bound up....

This is what is happening.

I have all the spacers in and the bearings all seated nicely....so I'm at a loss..

Any advice would be greatly appreciated.

Thanks, Dan

Exactly where is it binding..... By pic is flange hitting brace?...

You said all of the spacers are in, does that include the long one between the bearings? If it is in, could it be shorter than stock for some reason? If your center spacer is in and it is the stock length you simply have a problem of your aftermarket axle not fitting into your housing. Try putting a stock axle in and see if it fits. The profile of the back of the axle is important.

Thickness of caliper mount may be issue... By not letting everything tighten up to where all the "space" is removed between spacers as everything compresses.... Also maybe wrong outer bearing retainer... There are at least three different ones with seating depth of bearing being different in each one....

Could also be wrong spacer between inside bearing and flange...

I don't know if this link will help or not.

It shows the bevels on the spacers facing a certain way.

looks to me like the lip on the trailing arm needs to be shaved down, flush with the seal. or add another spacer to the axle shaft to space the cv flange out. but then you might not be able to tighten the nut down for cotter pin.

you can see where the housing scratched the CV flange.

Sorry, just trying to exhaust all possibilities. There's no way the inner and outer bearing got switched. The only thing left is the trailing arm width.

It looks to me that the back of the caliper bracket hits the back of the arm, keeping the bracket from seating against the outer side of the bearing housing.

You MAY have to make caliper brackets out of steel plate and weld them to the back of the arm.

So... I took the whole assembly back to the shop where I purchased them.

We assembled everything on the counter so he could see and he agreed that there was an issue.

He called the manufacturer of the arms and the suggestion was to use a swingaxle rear spacer and would check his other arms and see if this is an issue with them as well.

Apparently there are 3 different thicknesses of rear shims:

here's the difference between the one I *was* using and the thicker "swingaxle" shim:

That has cured my binding issue..now my aftermarket disc brakes don't fit...but I'll start a new thread for that....
