subaru impreza classic juddering ?
 

hi guys, just changed gear box diff and box ect, gear box is fine, but a very strange thing is going on, its starts to judder as im gettin faster threw the gears no engine knocking or anything boosts (normally i think) but just a horrible judder :(

I know on old fords if you don't put the propshaft back as it was they can be "unbalanced", its not something like that is it?

yeah well the garage did it so i assume so....
could be a plug thats not been put it correctly ? omg so annoying :-|

Don't mean to sound rude, but did you check that the gearbox and the rear diff are the same ratios? If they are mismatched then you will get severe juddering and the centre diff takes a pounding.

Yeh they r ok I found the problem got a rip on the boost pipe
