Whiteline Steering Rack and Pinion Mount Bushing – 2008-2015 Mitsubishi Evo X

Eliminate Steering Rack Movement on the Evo X
The steering rack mount bushing on the 2008-2015 Mitsubishi Lancer Evolution X is a high-load location that directly affects steering feel and precision. When this bushing wears, the rack can move under steering load, producing vague on-center feel and imprecise response that’s particularly noticeable on a car used for spirited driving and track events. Whiteline’s polyurethane replacement locks the rack firmly in its mount.

Evo X Steering Precision
The Evo X is a performance car where steering precision is fundamental to its character. The rack-and-pinion steering system’s feel depends on the rack being firmly mounted. A worn mount bushing allows the rack to flex and shift under load — degrading the steering feedback that makes the Evo X engaging to drive at the limit.

Particularly Important on Track-Use Evo X Models
At track speeds and cornering loads, the steering rack experiences significantly higher loads than during street driving. A worn mount bushing that produces mild imprecision on the road produces more pronounced vagueness on track, affecting corner entry precision and confidence under braking into corners.

Pair With a Complete Front Suspension Refresh
If the steering rack mount bushing is worn, it’s worth inspecting the rack itself, tie rod ends, and control arm bushings at the same time. A comprehensive front refresh on an Evo X produces a significant improvement in overall front end feel and confidence.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979.

The RallySport Take

An important component for any Evo X owner who drives the car seriously. Steering rack mount wear is a common failure mode on high-mileage and track-used examples — polyurethane replacement is a permanent fix. Budget an afternoon for the job — bushing replacement is not complicated but does require the correct press tools and clean installation technique. Apply grease to all polyurethane-to-metal interfaces and assemble at ride height for correct bushing set. The improvement in chassis feel is immediate and the polyurethane will outlast whatever rubber is in there now.
