Sierra Diff question for my MK Indy
doobrychat - 27/5/26 at 10:15 AM

Hi Guys and Gals.

After selling my indy I've got another one as I just could find anything else that was that much fun as a 7 style car.

My diff is super clunky being a bec and I fitted the electric reverse In which highlighted the next problem.
The input flange has play in the bearing so I've removed it to exchange for a diff I bought sometime ago but has small shaft where as mine is large shaft.

Trying to find a specialist for doing diffs is tricky as transmission places don't want to know.

So my question is.
Can I get a lobro diff and fit a bolt on CV joint on my large driveshafts?
Or can anyone suggest other options?

Many thanks in advance.

Diff specialist would be road and race transmissions in sevenoaks.
Unless they've changed massively their web site makes them look flasher than what they are.
When I went it was 2 guys who knew their stuff. Pulled my titan diff apart there and then, while telling me that the last specialist had put things in backwards or in the wrong order. Very knowledgeable.
Might be worth a call.

After they finished, it worked better than ever.

Bara Motorsport supplied a fully refurbished and rebuilt diff for me and I'd fully recommend them. The diff is high quality and they were great to deal with.

This is a pretty accurate description! If memory serves correctly, I believe they do a lot of work for Caterham Academy in terms of diffs and gearboxes, but definitely know their stuff.
