Good evening guys . Looking for abit of info for the internals of the Jdd gearbox and the standard one from the 75bhp 1.4 tdi box . I've done the Jdd conversion and it was great but I've had to go back to the standard box as the Jdd differential had started to grind on light deceleration and acceleration.
So the question I have is are the two differential internals interchangeable as I'm not a fan of the standard box since using the Jdd for a 18 months .
Cheers for any help.

May be but not what you want as a lot of the higher gearing on the jdd is due to the diff or final drive being a higher ratio
So if you buy the std tdi diff in the jdd box (assuming it fits) the gearing would be almost back to standard tdi gearbox

Cheers Paul. I shall strip the Jdd gearbox and rebuild with Jdd internal refurb kit . I'm assuming it may be the diff bearings have play . If not will strip for the parts and find another Jdd box.
