Great price on a rebuilt, I spent more then that on my 4:10

Same here. I had my 4.10 LSD rebuilt in Germany and I paid more than $750.

Good price. Do you offer a warranty on it at all?

[agent]

Yes, all rebuilds will carry a one year warranty. I'll update the OP with that info as well.

when you put it back together, how many teeth do you check the lash on?


ok, so i have a 3.38 ring an pinion that i want installed and set up in my own case. the case i have is really low miles 4.10 torsen out of a z3. i don't think the bearings need to be replaced, but i would like all new seals. i will ship it to you in a crate that will cost me about 60.00 with my fed ex account. you can keep the 4.10 ring and pinion to perhaps help offset the cost a little. you can ship it back to me in my already built crate.

so....basically... tear down, change gear set, replace seals, replace bearings only if they really need it, set up new gearset, and send it back.

can you please work up a price for me on this?

325IX Love?

Any chance I could ship you the 4.10 VLSD from my IX to rebuild? Or price of one you source to be rebuilt?

I'm interested in a few months

I think this is a great price for what you get. I'd get one just as a spare.

New ring gear bolts?
New cap bolts?

I'll PM you guys with the answers to those questions as soon as I get them.

New cap bolts?

If by cap bolts you're talking about the eight 6mm hex bolts, yes, those are typically replaced as part of the process. The newly installed ones are deeper to prevent them from rounding as easily as the shallow factory ones are prone to do. We simply reused mine since they came out and went back in without any drama.

Unless the ring gear is being swapped, I don't believe there's any point in removing and replacing the ten bolts that hold it. Though if you like, I'll be happy to confirm that.

Could it also be because you can buy the deeper socket ones from McMaster-Carr cheaply, while the OEM pieces are NLA?

I believe there is a very big point, when one of the most common diff failures I come across is caused by the bolts backing out. BMW even replaced the part number with the version that has the serrated underside.



Might be worth it as a preventative option for your customers. Good luck.

It very well could be. I don't know where the replacements are being sourced, but I'll find out if you like.

I'm not the factory-trained tech with more than four decades experience who's actually doing the work, so I'll once again defer to him on whether or not this is something that's included, and find out for you. Thanks for your input.

In addition to the 3.73 LSD, there is now a 3.25 LSD also available.

Feel free to PM me to discuss additional options and services.

[dishwab]

I wish I could afford this right now. The 3.25 would be perfect for my M30 swap

The 3.25 LSD is pending sale.
