What this part changes
The original bushing is made of rubber: it filters well, but deforms under load. When cornering or braking, the control arm moves by a few millimetres and the geometry changes during the manoeuvre - this is the slop 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, there is more road noise and vibration in the cabin, especially when cold.
What to plan for
- Install greased with 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 anti-roll bar before converting everything to PU.
