Hi guys,

My mk3 spit's diff is really whiny so I've bought one to rebuild of ebay. I'm looking for a recommended company to undertake the recon.

All suggestions welcome.

Cheers,

Ross

I've never done a Triumph one, but have rebuilt 3 (of different ratios) for the Sprite, its not that difficult to do once you get your head around it. If you fancy having a go yourself i could help with a few links.

Mike papworth has an enviable reputation. Probably available cheaper elsewhere, but riskier.
trouble is, with a used crownwheel and pinion it is not always possible to build a silent diff. However, shouldn't be too loud if set up correctly. I know a local chap and he talked me through how to do it. Sounds easy when said quickly over a pint

They whine when the case hardening has worn through and no amount of setting up will solve that problem.

Yes, true if its worn out, but new bearings, shim & thrust washers can make a huge difference, the critical bit is the pinion preload setting, but you can make a tool for that for about 1p, heres a picture of my expensive 1-10lb/ft torque wrench, patent pending
