What this part changes
The original bushing is made of rubber: it filters effectively, but deforms under load. When cornering or braking, the control arm moves by a few millimeters and the alignment changes during the maneuver - this is the vagueness between the steering wheel and the wheels.
Polyurethane deforms much less: the connection becomes precise and repeatable, and the car responds at the same point every time. In return, more road noise and vibrations enter the cabin, especially when cold.
What to plan for
- Install with grease made for PU or silicone grease - never use mineral grease, as it damages polyurethane.
- Tighten to the specified torque with the wheels on the ground.
- On a family car, start with the front stabilizer bar before converting everything to PU.
