R200 Shimming

[boatlyf]

Hey guys,

Pulled my diff apart today which is a standard viscous LSD to put some shims in. I noticed the right side shim which is 0.8mm has worn and is pitted and warped, the left side isn't as bad and is 1.4mm. When i went to pull the centre out i didn't have to force it much to get it out, so I'm thinking of changing the bearings as well. The diff felt pretty good before i pulled it apart and i was happy with the backlash. 

I have read most people are putting in a 0.8mm shim each side on top of the original shim, this seems like a lot of shimming but i just want to here peoples thoughts.

 

Cheers

Shimming VLSDs is doing the wrong thing.

so if the shim has play, from obvious signs of wear, what do you do about it?

In a completely stock VLSD, the shim does NOTHING except set the clearances.  The viscous cartridge inside the diff does all the "limiting" of the slip.

[Word redacted to avoid insulting people]s who have no understanding of these things like to jam thicker shims into the space between the housing and the centre to jam it all together harder and create a new friction surface outside of the centre.  When it wears, they express surprise and jam another one in there.

The correct thing to do is to f**k the VLSD centre off and put a proper diff centre in there.
