Tighten Up Front Axle Control on Your Jeep
The front upper trailing arm bushing takes constant load every time your Jeep flexes over uneven terrain, and worn rubber here shows up as vague steering, wandering on the highway, and uneven tire wear. The Whiteline W51749 front trailing arm upper bushing kit replaces the tired factory rubber with Whiteline's synthetic elastomer compound, restoring accurate axle location on-road while still holding up to real off-road articulation.
Key Features
- Synthetic elastomer bushings restore precise front trailing arm location
- Reduces axle wander and improves on-road steering feel
- Superior elasticity and memory compared to factory rubber
- Built to handle off-road articulation without premature wear
- Backed by a Whiteline Limited Lifetime Warranty
