i have a VT V6 auto i did a conversion with my diff from the standard one wheeler (3.08 gears) to a LSD (3.46 gears) out of a VU SS. I did it myself and it was a bit of a mission but defently worth it. it makes a bit of a whine but i am shore its a worn bearing and will get it fixed early next year once my pay goes up (apprentice wages suck) could it be anything else? i need to find the ppk value for that ratio? can anyone help please! benji
