Vy one tonner diff ratios.

[Doom vy tonner]

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
