Recently had a recon escort rs turbo gearbox put in my mk2 orion. The box was rebuilt with a 2nd hand LSD - which works fine.

A couple of weeks after the box was fitted, the car has started knocking when i reverse whilst turning left, doesnt do it when i turn right. I was told driveshafts/CVs could be worn so i fitted a brand new pair of driveshafts which illiminated a slight clutch judder that i had but the knocking still remains.

Any ideas ppl?
