LSD flange questions

[Jared]

I have a question about the output flanges that bolt to the CV joints. The LSD I got didn't have them, so i was going try to find some off a 320i at the local pick and pull. How do they pop off the side off the diff? Is it just a clip? What tools will I need to bring?

I also got CV joints from a 79 320i that I was going to put on the 02 axles. So basically I just need spacers after I get the side flanges, right?

(I've read the LSD searches, but just want to double check on what mates up together.)

Thanks in advance

is this going to help about the first question on how they pop up ?

Ireland has an article about the various diffs in their tech section, here:

With the mixing and matching you're doing, be sure to double-check your CV hardware at both sides (remember, your 02's stub axles (at the wheels) will have holes for the 8mm bolts, not for the larger bolts used on the later E21 CVs).

FYI, I'll be putting a 3.90 LSD with drilled flanges, spacers and bolts on the FAQ or eBay in the next day or two (like the complete set-up Aardvarc sold on ebay recently) - taking photos in the morning.

Hey,

When I bought my 3.90 the old hubs "popped out" ( One was a little beligerant ) and the 02 ones snapped in. Spacer plates were required.

I hope this helps you out.

I agree with the above. I just finished this mod...so here's what I discovered. The flanges just pull out/push in....that's why the spacer is so important. I took my old half-shaft, changed to a 320i CV for the inner (10mm bolt holes), left the 2002 CV on the outer (8mm bolt holes to mate up with stub axle) and added spacers from Ireland. Oh yeah, it seems obvious now, but you need the longer 10mm bolts for the inner CV to flange so you can reach through the spacer. I also took the time to change out all the gaskets and seals in the old diff to save future oil issues. Here's a pic

but 'pull' out is relative-

I often have to get behind the flange with a screwdriver,

then hit the handle pretty hard to dislodge them.

It takes a jolt.

And reinstallation can be difficult with the diff in the car-

the snap ring likes to drop out of center and block things up.

hth,

This is a really confusing topic.

I thought that if you had 320i diff flanges, and '79 CVs on one end of the 2002 axles (2002 CV's on the other end) you would be good to go without spacers.

Anyone?

i have both types of lsd, you can use the 2002 non lsd flanges and have the groove for the circlip machined.

no spacer required.

Pat- I think this is only true with the flanges from a 76- no?
