No more r3vtard assist

You were bang on, ordered two new clutches after a little cross referencing the differential carrier part number and found the numbers on an e24. Parts were in stock (3 left, with discontinued status according to the dealership). Ordered two plates and the parts should be here this week. Thanks Wangan.

Gotcha, stock parts it shall be. What is the part number on the clutch disks? Bimmerworld suddenly has them listed as unknown delivery date.

Run stock parts avail from your bmw dealer; it's good enough for a E36 m3.

Bump for some wisdom!

I just picked up a 3.73lsd that I'm looking to rebuild, the bearings and seals are simple enough but I'm hoping for some input on my clutch selection for the diff.

I'd prefer to have the car drive like stock, with the added detail of being S52 powered. I primarily daily drive it but I do a few autocrosses and trackdays each summer. I'm not afraid of a little oversteer but I don't care for drifting everywhere every day.

With that in mind would you suggest grabbing a set of the stock 2.0mm dog ears and a pair of clutches from Bimmerworld, or should I grab the thicker Porsche 2.1mm's like I saw briefly mentioned on another walkthrough? My instructor at the track did say "more motor, more diff" when I asked for his input.

Hell if you have any suggestions, I'm open. I will be having a shop do the work and the guy recommended grabbing the parts myself to save time/money. I'd like to avoid getting into machining parts.

There is something called realoem.com that is for that kind of puzzle

Not sure if this is the best place to ask but what differential came in a 2000 z3 auto? Last 7 of the vin are LG18398

I just don't ever say anything is 100% untill I set one up w my own hands.

This is my philosophy as well.

If 2013 motorsports 4.10 and 1984 2.93 can direct interchange lsd units why not 2.65


What front diff ratios are avail for the setup u want to run?

Like I said, it's very very likely that the 2.65 uses the same carrier as everything else... but the 2.65 pinion is a lot bigger than the 4.10 pinion, and the ring gear can only get so thin.

The front diff was a disaster.

The E53 and E46 diffs are very similar. They both split vertically, with the right bearing held in a cover that unbolts. The pinion and the left bearing are in the main case.
The distance from the right bearing to the pinion centerline appears to be the same, so a 2.35 or similar from a diesel E46 could *probably* bolt to the carrier from an E53 and work.

However, there are two different main (left) cases for the E53... a low ratio and a high ratio. The low ratio case has clearance for a larger pinion than the high ratio case. So I'd need to start with the 3.07 front from a Euro market E53 X5 3.0d w/ manual transmission. I'd also need to get the 2.35 or whatever from a Euro market E46 diesel with manual trans.

Since the ratios I want are pretty rare and expensive AND have to be shipped from Europe, I'd end up with close to $2K invested in the parts without even being *SURE* that I could bolt it together.

So I went with the GM TR6060 six speed... probably more expensive overall, but will be good for 1000 HP with 32 spline output shaft and works fine with 3.64 gears that are readily available for front and rear, 188 and 210, in the US.

One 25% LSD is PN 33141206745 shown here for E23 745i: http://www.realoem.com/bmw/showparts...88&hg=33&fg=15

The other I found is 33141210707 shown here for E34 540i: http://www.realoem.com/bmw/showparts...85&hg=33&fg=15

Those two part numbers cover most of the 210mm LSD apps.

However, RealOEM doesn't show parts breakdowns for the diff for cars that have the 2.65 and doesn't list the LSD by itself for the E31's.

I've played with the PN's for the open diff carrier, but I can't find anything definitive.

I agree it's highly probable that the 2.65 uses the same carrier as everything else. Knowing it came in 850's helps a LOT. There are a couple of MT diffs listed on www.car-parts.com right now, but none of them say limited slip or locker.

On a different note, I'm putting together an E34 auto to manual swap kit from my wrecked 535i. It uses the 6 bolt diff flange. From the "where used" function on RealOEM, it looks like pretty much all E34's used the 6 bolt flange. Is that correct?

I couldn't actually see where the 6 bolt flange was used... It's not listed separately. I could only see where the 6 bolt CV joint is used.
