Ghostwalk the Whip: Fixing Subaru bump steer with Whiteline Bushings

,

Before the install, note what the trailing arm should look like when it is centered properly within its mount.
On the passenger side you can see the trailing arm has shifted towards the center of the car and was completely torn away from the bushing. It was loose enough that it could be moved by hand and had some wicked toe change while driving down the road.┬áThe Whiteline bushings’ shouldered design does not allow the arm to move back and forth, something I feel like the factory should have taken into consideration.
Here’s a closer look at how the trailing arm and bushing have parted ways.
We, and by we I mean Grant, were able to install the new bushings without having to remove the trailing arms completely from the car. First, he started by removing the brace that connects to the trailing arm mounting point.
Then it is as simple as removing the bolt that connects the trailing arm to the chassis and pulling the arm down. The bushing on the passenger side came out by hand, but left the steel ring that was pressed into the trailing arm.
Using an air chisel, Grant removed the steel ring in a matter of seconds.
Here’s what it looks like after a rough day in the office. The driver’s side bushing had not separated in the same way, but the air chisel took care of its removal all the same.
