Diff Seals, BMW vs OEM vs Generic

Recommended Posts

I'm giving my 210mm LSD a tidy up (removing 30 years of gunk off the outside) before installing it into my e28. In doing so I'm replacing the seals. What're people's thoughts on genuine BMW vs, OEM, name brand (e.g. Victor Reinz) or popping down to my local bearing/seal shop?

My understanding is, is that they're just a relatively normal seal and I just need to match the ID and OD and mostly match the thickness (currently running a 10mm instead of 9mm input seal).

  • Output shaft, 76X50X10, 33107510289
  • Input shaft, 50x80x9, 33121213949

And of course a new locking ring 33121205138. Anything else I'm missing?

Only had one problem with VR and that was a headgasket along time ago. Used their diff seals a couple of times.

I have 2x VR output seals\rings with that part no if you want them - $30 incl postage if you want them
