Hey all I needed to replace my rear knuckle and I bought one that I believe has the 75mm Wheel bearing and mine has the 82mm. Is it possible to just press out one bearing and put the old one onto the new part or are the knuckles themselves different sizes? Also would it be possible to put a 75mm axle on and just use the 75mm bearing? I'm looking for the cheapest way that will work.

Thanks!!

must press fit into the bearing housing.

Are the 75mm and the 82mm the same outer diameter? so the hub can fit both sizes? I checked my etka and the hubs p/n's are:
8e0 505 436 l 75mm
8e0 505 436 n 75mm
8e0 505 436 p 82mm
8e0 505 436 j 82mm

They look identical except where the bearing is.

I know the end that goes into the bearing is a different size but is the end that goes into the differental and axle shaft and everything the same size?

Thanks

bently didn't seem to help me much here.

I have a hub from a passat/a6 2.8 that has a 75mm bearing

My hub is broken (from 2.7 a6) and it has a 82mm bearing.

Everything bolts up fine except for the axle into the bearing they won't match up.

So I'm wondering if the bearings are interchangeable or if the axles are interchangable?

the hub. Seams obvious that you can not use a 75mm bearing in your 82mm bearing housing. Your replacement hub must both fit the half shaft's CV joint spline and the ID of the 82mm bearing. Further, the hub's wheel mounting face needs to be the same distance from the bearing housing's bearing seat as was the original. You go figure!
