Well ive just measured my gearbox angle and where the rear seal is i have precisely 1.3% down bubble (from a spirit bubble not any angle on the suspension)

I think i know the the problem with me having to much traction under torq and not enough under top end

Diff angle around 9%

The good thing was there was no vibration (well not noticeable)

So when i re mount the rear end looks like ill be changing the angle

Do you think that i should change both or just mount the rear to match the front
