to removal, bc it is on too tight, the bearing comes out with it.
Use only GKN...
Or a good used BMW axle (made by GKN).
Seal: Corteco.
I wrote a full DIY on bimmerfest E53 forum in 2025...
PS: when it comes to axle, seals, I only use original mfg bc this stuff is down
to 0.03 mm etc. And this is the job I don't want to do twice.

Yeah I'm thinking this might be the source of the bearing sticking. The axle removed was also a GSP replacement. I got the new ones from Turner with "lifetime replacement" so if they end up being junk I'll take that credit and apply to GKN for round two. The other parts, seals and carrier are BMW OEM. Fortunately when all the parts arrive I can dry fit it to see what the clearance is like. Maybe emery cloth the axle a bit if it's on the tight side to get that .03mm back -
I went into this job expecting a wrestling match or too, but got from jack stands to CV out in about 40 min. for the one side. Helps that there is very little corrosion.
