Hi guys. I have concerning light grinding noise coming from the rear of my car. The diff is only 30000 km old so I hope its not that. Could be a wheel bearing also. If I do have the change the diff I was wondering if there were some cheaper options and how I go about getting higher diff ratios. Like 3.8 or something around that. Cheers
there are many many options but first have you changed the oil and put in the holden additive mine used to grind on slow turning and in reverse, put in fresh oil and the stupid additive and hey prsto like majic
was tending to be worse when it was hot
Ok cheers. What is the Holden additive?
its just an LSD lube available at most auto parts stores, i used a penrite one ill have a look and see if still have the little bottle and give you exact name
