Did this work? I may have a worn inner joint. -
Yes the GKN 302303 appears to be the correct inner CV, however the end caps and boot are different, I would use the E46M part number for those. You will have to bang the inner CV in pretty good to get it to seat all the way.Originally posted by maupineda View PostAttached FilesLast edited by CrookedCommie; 04-30-2025, 07:01 PM.Comment

Like the spline in the CV is not the exact size?Originally posted by CrookedCommie View PostComment

I've not installed a new bmw one, I believe it's the same size but they are tapered so installation requires a bit of force. Clean the axle and new CV splines with a drill wire brush, use brake cleaner, grease both up. Take a big socket and bang against the inner part of the CV, TAKE NOTE of the orientation of how it goes in. The side with the lip goes towards the middle of the axle, the flush side goes towards the outside of the axle. Put the axle nut on so you don't damage the splines and bang the axle against a 2x4 or something soft so you don't damage the outer CV. Bang until the circlip can go in.Originally posted by maupineda View PostComment

Some more info regarding the axle rebuild:
The outer E46M Vaico boot kit came with the correct clamps, but you will have to trick the big 68mm on, use a small hobby screwdriver through the slots to lock it back onto the tab. The inner boot kit came with too small of a clamp for the small side of the boot, see below for the correct one.
To clean the outside CV, I got as much of the old grease out using shop towels and letting it drip out, then used a bucket of gasoline to clean the rest out, by basically jerking the axle in and out of the CV. Use compressed air to blow out the gasoline and grease. Repeat until clean, inspect for any pitting, as a final measure I used brake cleaner to make sure it ran clean out, then dry it out with the compressor. Note that the axles are hollow and there may be old grease in the middle of them. Repack using Redline CV2 and work it back in. Grease the axle shaft and sneak the new boot in through the inner CV side.
For the inner CV grease caps, I used the GKN ones that came with the E46M kit, it is easiest to use a rubber mallet to get them started, and the edges of an anvil and a 2x4 block with a hammer to press them all the way back into place evenly.
Overall this cost me roughly $300 in parts because I had to get two new inner CV's. E46M axles are still available new in Europe but go for $1500+ This is a motherfucker of a job but well worth it, you do not want to miss out on a track or race event due to a bad axle. I will be wrapping the exhaust that goes over the driver side axle to keep it from cooking the grease.
I will update the thread once I get the race car on the track and have ran the axles through the ringer, I have a spare set of shafts that I will rebuild using this method as backups.
Parts I used:
2x Outer boots
2x Inner boots
2x Inner CV's
One jar Redline CV2 should be enough to do two axles:
If you use the E46M GKN boot kit, it comes with too small inner clamp, use this one:

I just want to add that while the rear axles are removed, it is the perfect time to replace the rear wheel bearings, especially the driver side.Comment

Dumb Question, but would the Porsche Kit mainly just be for the inner joint itself when doing the refresh?Originally posted by CrookedCommie View PostSome more info regarding the axle rebuild:

Exactly, just the inner CV. The boot and grease caps are different. I couldn't find the e46m specific part number.Originally posted by dHam_Slow.46M View PostComment
