A mates father in law has a mk4 fiesta courier van for his work van and it has developed a knocking noise from the rear.

on inspection we found that the bush that holds the axle to the torsion bar setup and mounting bar has vanised basically...

has anyone replaced these bushes?

I have looked on FORD TIS and there is no mention of replacing these but they are listed on microcat....

has anyone replaced these before and has anyone got any hints or tips on how to do them?

is it a case of whole beam off or can it be done in situe and does the whole torsion bar have to come out or can it be done with just the mounting bar off the end of the torsion bar as thats only one end to line up as i presume its like a pug setup and it adjusts the ride height as there are no springs....

also are mk5 couriers the same rear setup as the mk4 ones? if so are the 2 beams interchangable?
