LSD Oil and general inspection question
12. Jan 2011 at 15:09

Ive had a quick search on here regarding the correct oil type for an LSD. Instead of buying the GM diff oil and adding the correct additive specific to the LSD, can i just put generic LSD oil in it like this?

http://cgi.ebay.co.uk/Castrol-B373-LSD-Diff-Competition-Oil-Race-Rally-1L-/27068...

And before i put the diff on the car, are there any checks i can do to test it? I wouldnt want to fit it only to find i have to pull it out to rebuild it.

Might be wise just to change these before fitting as it's a lot easier on the bench. Also check it hasn't got too much backlash. Kevin

Jan 2011 at 15:23 Yep, back plate is already off the car. Ive spun it round, and cant see any wear to the crown wheel or pinion, but thats all i can see as the clutch plates are still in the case. How do i go about checking backlash? Yeah ill replace the output seals, as one is a bit wonky. Is Vauxhall the best place for these?

Jan 2011 at 15:29 why would you risk a perfectly good lsd?? ppl are asking around about them and you risk yours with some noname oil. the genuine gm can't cost more than 20pounds on a trade card with aditive that is specific for this kind of lsd.

I dont have a trade card. The LSD additive was a bodge by vauxhall as it wasnt cost effective to stock specialist LSD diff oil after their original stuff ran out. So they supply standard GM diff oil of which you need .75 litres then you have to add their 'special' lsd additive .25 litres. This increases the viscocity of oil to make it work with the lsd clutch plates. So its actually Vauxhalls bodging and im thinking now it'd be better to just use quality after market stuff. Just found this out by reading up on the Carlton forum.

there are ppl here who could help you buy with a trade card. all i was saying that it could be hurting it Sad
