Thanks for that Multibeemer.
On the Axle nut: A new one comes with remanufactured axles. THEY SHOULD NEVER BE RE-USED!
These nuts are specifically designed to be disposed of once they are removed. This is very important to anyone doing any type of job that requires removing them.

That's what I thought, and that's one of the reasons I decided to go in through the inner joint, since I wasn't sure how easily I could find a new collar nut locally. Going in through the inner joint is actually pretty straightforward in principle, as it's easy to knock the tripod joint off the axle with a hammer and a punch. It's just the the overall job has a lot of steps that make it pretty time-consuming, and if you do it without an assistant like I did, maneuvering the heavy axle/strut/hub assembly can be a real pain. Hopefully, this will be a once-in-the-life-of-the-vehicle job.

A new axle nut comes with the outer boot kit.

Multibeemer, glad to hear you got the job done.
I'm still waiting for the Oetiker clamps to arrrive before I tear into mine.

You mentioned the clamps were a little tricky to get them crimped on tight. Can you give some specific tips or tricks in doing the clamps?
Also, did the tripod bearings tap off easily with a hammer?
I rented a joint puller just in case the hammer doesn't work.
Any other tips would be greatly appreciated.

On the topic of the "special grease", while waiting for mail order parts, I googled inner cv joint grease, and found one offered from a Honda parts website.
It's labeled "cv joint grease inboard" so I picked up two tubes ($8 ea, 4.94oz/140gm) from a local Honda dealer.
There happened to be a technician hanging around and I asked him about the joint grease and he verified that they use different greases for the inboard and outboard joints. Hopefully Honda grease is good enough for BMW.

I'll take some pictures when I do the job and try to compare the grease that comes out to the Honda grease.

I'm the one that found the Oetiker clamps, they are not tricky to to put on at all, just position them so that you can get a good grip on the pliers, nothing to it. Just get a small hammer and give the bearing some good solid licks, nothing crazy, it will come off. If you knock one of the bearings off don't worry, you can just tap it back on during the reassembly. Be sure and let us know what the viscosity of the Honda lube is like, the OEM stuff is more like an oil than a grease. When I did my boots, the inner lube ran out like a thick oil change.

You are right, romeokc10. You did post a link to the store that sold individual Oetiker clamps earlier in the thread, so thanks for that and the additional tips on this procedure.

Here's the link for the clamps posted by romeokc10 in case you don't want to read through this entire thread:

I definitely will post a follow up regarding the Honda grease.

I agree with romeokc10's assessment. This was the first time I had dealt with Oetiker clamps, so it took me way longer than it would have if I had done this before. I spent a lot of time making sure I got the clamps as tight around the boots as I could before pinching the protruding crimping nub thingy. I was afraid that if I didn't get the clamps at their tightest possible position prior to the crimping step, I would run the risk of the crimping not having sufficient room to fully tighten the clamps. Doing this is very awkward, as you have to hold the clamp with one hand to keep it from turning on the boot while using the other hand to try to push the clamp to the next position. This wasn't an issue with the clamps taht came with the boots, because they were sized to fit perfectly to the boot. The clamps I ordered from the site romeokc10 mentioned were adjustable, so I wanted to make sure I got it right before crimping. In the end, it all worked out fine; as I said, I spent way too long on this.

I also had a little trouble breaking the old clamps open. It must have been just me. For some reason, this step went much faster on the drivers side. Having the right size wire cutters would be a big help here.

I also had no trouble whatsoever knocking the tripod joints off the axles. I just used a hammer and a blunt-ended punch. The positioning can be a little awkward, but once you get yourself into a comfortable position, it's pretty easy. I used a 27 mm socket to drive it back on. Make sure you drive it on all the way to allow the circlip to fit into its groove.

Romeokc10 - My outer boot clip did not come with a new collar nut, which greatly influenced my decision to go in through the inner joint.

Tspeed - Sounds like you may have found some suitable stuff to use as grease on the inner joint. In my case, I was careful to preserve as much of the existing stuff as possible. I used about a tube of the CRC stuff on top of the inner grease that was left. Very little dripped out, particularly on the passenger side. Good luck!

Now that the job is done, there's a small detail that's been bugging me, and I'd like your guys' opinion on it. On the drivers side boot (the first one I did), I didn't compress the boot enough to get it to the indented part of the axle before applying the clamp. On the passenger side, I did. So, I'm wondering, should I remove the small clamp on the drivers side and move the narrow end of the boot closer to the outside of the axle, where it has the indent, and then clamp it down? I have a spare small clamp, so it wouldn't cost any more, and it would only take a few minutes. Or does it not matter? Thanks.

It doesn't matter, if it's not leaking leave well enough alone.

OK, thanks. I was just concerned that if it's clamped too far inboard, it might get stretched too much during extreme turns, and wear out prematurely. I definitely don't ever want to do this job again!
