What this part changes
The original bushing is made of rubber: it filters impacts well, but it deforms under load. When cornering or braking, the 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. The trade-off is more road noise and vibration in the cabin, especially when cold.
What to plan for
- Install lubricated 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 anti-roll bar before converting everything to PU.
