55270-2W100 BUSH FAQ

How often should I inspect this bush?

We recommend a visual inspection every 40,000 km, especially if you drive on unpaved roads or in regions with heavy salt use.

Do I need an alignment after installation?

Absolutely. A full 4-wheel alignment is mandatory after replacing trailing arm bushings to ensure the thrust angle is correctly set for vehicle stability.

Questions and Answers

Is this bush for the left or right side?
The 55270-2W100 is typically non-directional and used on both the left and right rear trailing arms, though we recommend replacing them in pairs for balanced performance.
Does this part affect the vehicle's alignment?
Yes. While it is not an adjustment point, a worn 55270-2W100 BUSH allows the trailing arm to move out of its intended position, which directly affects the rear toe and thrust angle.
What causes these bushings to fail?
The most common causes are environmental exposure (heat, road salt, and moisture) and the natural aging of the rubber, which loses elasticity over time.
Why choose this specific OEM-spec bush?
Using the correct 55270-2W100 specification ensures the rubber density matches the factory-tuned suspension settings, preserving the original ride comfort and safety of your SUV.
