Okay, so here are two more mysteries. I ordered the following parts:

999-090-010-01-M100 - wheel hub nut, front, left or right, 911 Carrera 2/4 (1989-94)
000-043-301-08-M60 - CV boot kit, 964 Carrera 2 (1989-94)

The parts do not quite match up to the old ones from my car, though, so I want to make sure I have the right things in hand before I start putting them together.

First, the wheel hub nut. This is a picture showing the old and new together. Note that the new one is much shorter than the old one. Is this just a superseded part that I need not worry about?

Second, the axle flange/cap. Note that the part number of the CV boot kit that I ordered does not expressly say it is for the front inner CV joint of the Carrera 4, but if you look at the Pelican kit to do all 8 CV joints on the Carrera 4 you will find six of this part number plus separate parts for two more CV boots, the boots themselves of which are named "CV Joint Boot, Front Outer, 911 C4." But if you look at the photos, you will see that the new one (on the right in the first photo) is much flatter and also (on the bottom in the second photo) a noticeably larger diameter than the old one. My inference is that I should reuse the old flange/cap and otherwise carry on with the kit, but I want to be sure that nobody has a warning against that out of circlip- or boot-related concerns.

Thanks again, everyone!

I would call Pelican and ask them and post up what they say.

Just for any 993 readers ... I got my kits from the dealer, and they had surprises too. The axle nuts were different they went to a self locking castellated nut. The circlips were different too. They were the cheaper 'pointy' style clips instead of a circlip with the holes for easy removal and installation. The caps had a different finish on them too. I called the dealer and the reason he gave was that the kits service multiple cars and the cheaper style circlips fit all which is why they put them in. I ended up reusing my circlips as they came out and cleaned up perfectly. Same with my inner caps. Finally. I believe the boot clamps from Pelican are better than oem if you got the oetiker (sp) style. THe oem ones are pretty flimsy but hey I guess they worked ok for 17 years. The oem clamps do have one advantage in that you can park them wherever you choose as they are low profile where as on the oetiker style you have to line the locking part up in between the cv joint bolts.

Mines a 993 C2 so again its a little different than yours but I'm just posting so people know if you order dealer kits, you aren't necs. going to get exactly what came on the car. I'd probably rec to go Pelican and save some $

Good tip. Answers from Pelican:

The wheel nut is a multiple-times superseded part. The part ordered and received is the current, correct part to use.

I should reuse the old flange/cap from the CV joint that came out of the car instead of the part from the kit. The rest of the kit should be fine.

New tip: The circlip is also the wrong size, so if you have thrown away your old one or even found it in the garbage, cleaned it up, and then noticed it was slightly damaged and then broke it into two pieces trying to put it on, you should order a new circlip separately from the CV boot kit.

PET illustration 401-10 part 9 shows that the part number for the circlip is 900.041.013.01. It's the same circlip as used on the telescoping replacement oil return tubes for the 911 engines. Unfortunately, while I had one of those, it is deformed and doesn't want to be flat.

While I wait for the new clip to show up, does anyone have any definitive answers to which way the inner race is supposed to face? There is a raised inner edge on one side and not on the other. At least two sources I found online indicate the raised edge goes toward the axle and the flat edge goes toward the differential. So that's how I put the joint together. It slid relatively easily onto the axle most of the way, but even with some tapping it doesn't quite want to go far enough to fully expose the groove for the circlip. It's hard to tell with my broken and warped circlips whether it's exposed enough or not.

All tips welcome. For now, the party is at a standstill. Thanks again, as always.

Well, I don't know about definitive,,,,, :) but MY inner race had some machining marks facing the axle side and the smooth side facing the transmission. Hope that helps :D

I cleaned the splines by brushing then with a stainless steel brush, gently, immersed in paint thinner then cleaned them with brake cleaner. Same for the inside of the inner race. Applied some anti seize and with a gentle few taps it left the perfect amount for the circlip. I hear ya though, without the circlip, that's hard to verify...
