Axle Support Bracket Bearing?

bigshooter · 08-02-2023, 03:47 PM

Hey guys, quick question on the axle support bracket - 31508653616, which attaches to the front diff and the passenger axle goes through.

Does anyone know if there is a bearing inside of this? I have a mysterious howling noise and no one can seem to figure out where it's coming from.

I am on Bilstein B14 coilovers with the front maxxed out. My theory is that being lowered, it has placed stress on a bearing in the axle support bracket or simply the pinion bearings in the front diff are pitted/toast. New wheel bearings and center support bearing. I just picked up a front diff but would rather not have to replace it if its something else.

I was told the bearing is not serviceable, but I came across this bearing kit for sale.

Old thread but did you ever figure this out? I might be having a similar issue.
