REMOVAL OF STOCK UPPER TRAILING ARMS
1. There are various methods for installing your new upper trailing arms. Preferences in methods are mainly
based on the way you remove the old rubber Can Bushings from the differential. Some may find it easier
to detach the entire differential (rear end) from the car in order to remove the Can Bushings. This makes
it easier to get at the Can bushings for removal and replacement. The only problem with this method is
that it requires much more to be disconnected e.g. brake lines, parking brake, axle u-joint, and lower
trailing arms. However, it is possible to remove the Can Bushings without taking the rear end off the car,
but it’s tricky.
In this manual, we will describe how to replace the Can Bushings without removing the rear end from the
car.
