My 2.0ltr 80se has just failed the dreaded MOT. it failed on the offside front strut having excessive movement in the upper support bearing assembly, both rear disc's in need of replacement and a rubber brake hose( offside front) bulging under pressure, what i want to know is do i have to replace the offside strut as a complete unit or can i just buy and fit the bearing assembly ??? all the other faults are easy fix. Thanks Dave..
