Title: LSD - Type & Adjustment
Post by: alank46 on 03 September 2009, 22:49:01

Hi
I've just fitted a used LSD purchased from ebay some time ago.  Its LSD function does not work although I'm fairly sure it is an LSD because when I had the back cover off before fitting it I could see some small compression springs in there.  Like an idiot I forgot to take any pictures. I'm assuming this is an optional Vauxhall LSD and not an after-market type, in which case what type of LSD is it.  The springs I saw suggest that it is a plate type diff, is this right.  Is there any means of adjusting the LSD function because as said mine does not work.  Parked with one wheel on the grass verge and the other on tarmac and then booted with the traction control off it produces a rooster tail of mud from one wheel and very little forward motion.  Very disappointing after all the effort of fitting it.

Any help and advise especially on ways to adjust it will be very welcome.

Thanks
Alan

Hi
Yes I am using LSD oil, Castrol B373.  Maybe that was the problem with the previous owner though, maybe he used standard axle oil without friction modifier and that has knackered the clutch plates, that is assuming its a plate type diff.  I bought it over a year ago and cannot now remember what the description said, but think it was claimed to be re-built.

Does anybody have any info on the GM LSD's, ie type, rebuild proceedures, adjustments etc?

Thanks
Alan

This might sound like a really stupid question - but I dont think that the Omega ever had an optional LSD.

I know that the Carlton & Senator did though.

I'd be very happy to be proved wrong on this BTW.

yes, it was an option, and often fitted to police spec ones  :y
