Rear diff oil grade?
 

I'm after a bit of advise as I'm going to be changing my gear box and rear diff oil on my 04 sti the oil listed for the rear diff is 75w90 but I thought it being an lsd it would use lsd oil? I've looked on forums ect and some say it's fine but few people say causes diff to make odd noises and should use 90LS

If any one could clear this up for me it would be great thanks

Speak with Alyn at AS Performance - but for my Bugeye he's just provided me with millers CRX 75w90 NT for gearbox and millers CRX LS 75w90NT for the diff :ok:

Ok thanks notice he sent you LS for rear diff by looking into it more seems I should get limited slip oil for rear diff and not just normal gear box oil

you definately want an LS grade oil, we carry various options and grades to suit both budget and exact use

I run a slightly thicker LS140 in mine, it gets some stick!

Think I'll go for the Crx 75w90 nt and Crx LS 75w90 nt for diff mine only get used on the road so shouldn't need thinker stuff lol

:ok:

is the stuff in "for sale" that scooby doo has not any good then???
