What is the correct oil that you guys recommend on the factory lsd?

I saw 75-90 and 75-140

Just want to see what is good for regular spirited driving and no track abuse.

Mort

The recommended LSD gear oil is Castrol Syntrax Limited Slip 75W-140. MB part #001 989 52 03 10.

Thanks guys it took a while.i was emailing cars on eBay that were salage and I found a white one and asked for the Vin and it came back 471 option so I asked him to pull the diff.

2012 with 62k miles got it for 800 shipped and he gave me a 90 day warranty!

There is one on eBay now for 650 plus shipping but it's an 08

Ok thank you!

You could have grabbed a Wavetrac for like $1000...

I got quoted like 5 hours labor just to install it in my old diff.this way it's plug and play

I've also done custom diffs gearing in my m3 and every time the diff was opened it never ran right.i would get whine and the seals would eventually leak.

Factory LSD is a clutch type LSD: 75W-140 oil, as Mort mentioned. Alternative to OEM castrol, Motul also has one 75w-140 LSD oil.

Ok I will just stick to OEM.how much oil does it take? 1 liter?

Mort

It will take 1.2-1.3L so get three 500ml containers depending on the size you can find for the best price. The dealer or online OEM will likely have 500 ml for $25- $30. Might be cheaper in the US or from other suppliers if you check around. Going from memory but I think I paid that plus tax from the dealer last time.

Ordered 3!!!

Can anyone confirm this is correct part number?

Mort

I ran that #2043504313 in OEDiscount parts and got no items matching. The current part # is listed as 2043501717. The regular diff w/o locking diff is #2043508614. It is possible that part # has been superseded or is not a direct cross over to the parts list.

Mort

On further checking the Locking differential part nos. are:

2008-2011 #2043509614

2012-2015 #2043501717

W/O Locking differential:

2008-2015 #2043508614

bro grab the vin off the car they pulled this out of and see if it has the lsd option ( 471 ) look for that.

Amr_c63

Or just spin the diff and look inside where the axles go and see if the gears are spinning at the same direction.

skratch77

Yea the Vin checked out but the guy has 3 c63s and I told him to make sure it came off the white wrecked one because that one had option 471.

Ok just spun it and both turn same direction
