Rubber bush for rear trailing arm inner pivot
Supplied in singles, Two required per vehicle.

This is the pivot bush for the IRS trailing / radius arm. Often neglected, this bush is vital to the geometry of the rear suspension. A worn or perished trailing arm bush can cause a knocking sound from the rear suspension as well as negatively affect the camber of the rear wheels causing undue wear on tyres and have a negative affect on the handling of your T2.
