Hey guys just recently changed the diff ratio in my Vl from 3.9 to 3.45 and now I get a bit of drive line vibration at low speeds is this just a normal thing because of a taller diff ratio with the 2 speed any feedback would be great thanks in advance

I run a glide with stock ratio, haven't got any vibrations. Maybe check your pinion angle as I assume you've had the axle off when you replaced the gears. If the pinion angle is out a touch, you can get drive line vibrations.

Agreed^^ There shouldn't be any more vibrations with the lower gearing. I recently did the opposite and went from 3:45 to 3.9 with my glide... it's ****ing **** on the highway [Image in original archive]

Yeah was thinking that I did change the upper control arms to boxed nothane ones and boxed the lower control arms aswell does any one know what angle i need like 15 degrees or something and I'm guessing the only why to change the pi�on angle is to use adjustable upper control arms ? ---------- Post added 18-11-15 at 12:48 ---------- Yeah Morgz I went back to 3.45 coz it was revving to high @ 100km when cruzeing happy with the 3.45 now
