Diff options

**Flix** · Sunday 13th May 2012, 12:47

I have a welded diff in my Autograss car but interested in trying a viscous diff, I understand they were fitted to v70r.
Would it fit into my M56H box?
And has anyone got a spare one?

You will need the m59 box plus the driveshafts as they are thicker, usually go for about 300 for the lot.

the viscous coupling is actually on the longer drivshaft not in the diff, so you will need to changing the gearbox casing as well

Might just wait and go for a Quaife then.
Hoping it would be a straight swap for mine.
Wheres the best place to get a Quaife? Are there any used ones available?
