SuperPro Steering Rack & Pinion Bushing Kit – 1996–2002 Toyota 4Runner | Polyurethane | 1836K

Few repair and upgrade items deliver the improvement-per-dollar of a high-quality replacement steering rack bushing — and the SuperPro 1836K is one of the best examples of that value proposition. Replacing the fast-wearing factory rubber bushings with SuperPro’s polyurethane steering rack bushing kit reduces slop, movement, and deflection at the steering rack mount, resulting in more consistent, more accurate steering feel and function on your 1996–2002 Toyota 4Runner. Properly anchoring the steering rack eliminates the vague, wandering feel that develops as the factory rubber bushings age and deteriorate — reducing the need for constant small corrections to maintain course and restoring the crisp, connected steering response the 4Runner was designed to deliver.

Why Replace the Steering Rack Bushings?

The factory steering rack bushings are made from soft rubber — a material chosen by the OEM for its noise and vibration isolation properties, not for steering precision. Over time (and especially on a 3rd gen 4Runner that may be 20+ years old), the rubber hardens, cracks, and compresses unevenly, allowing the steering rack to move under load. The symptoms are familiar to any 4Runner owner: vague on-centre feel, wandering at highway speed, imprecise turn-in, and a general sense of disconnection between the steering wheel and the front wheels. SuperPro’s polyurethane bushings are significantly firmer and more dimensionally stable than rubber — holding the steering rack in its correct position under all driving conditions and restoring steering precision without the harshness of solid metal mounts.

Key Features

• SuperPro Polyurethane Construction: SuperPro’s proprietary polyurethane compound is engineered to be significantly firmer and more durable than OEM rubber — resisting compression, deformation, and deterioration from oil, heat, and UV exposure that cause rubber bushings to fail prematurely. Polyurethane maintains its dimensional stability over a far longer service life than rubber, making this a genuine long-term upgrade rather than a like-for-like replacement
• Reduced Steering Slop & Deflection: By eliminating the compliance and movement of worn rubber bushings, the SPF1836K restores the steering rack to its correct fixed position — reducing the slop and deflection that causes vague, imprecise steering feel. The result is more direct, more accurate steering response with less on-centre wander and more confident turn-in
• Improved On-Road Accuracy: Anchoring the steering rack properly reduces the wandering and course-correction fatigue that develops with worn factory bushings — particularly noticeable at highway speeds and on uneven road surfaces where steering rack movement is most pronounced
• Street & Performance Upgrade: Whether you want to restore factory steering precision on a high-mileage 4Runner, improve feel and accuracy for performance driving, or simply want a more consistent and predictable drive, the SPF1836K delivers significant improvement at a fraction of the cost of a full steering system rebuild
• Direct OEM Replacement: Engineered as a direct replacement for the factory steering rack bushings on the 1996–2002 Toyota 4Runner — no modifications required. Installs using standard bushing replacement tools and procedure
• SuperPro Quality: SuperPro is an Australian polyurethane suspension component manufacturer with over 30 years of experience engineering bushings, control arm kits, and suspension components for OEM and performance applications globally. SuperPro products are engineered to precise dimensional tolerances and friction specifications for each specific application

Note: Polyurethane bushings require lubrication during installation — use the supplied SuperPro grease or a compatible polyurethane-safe lubricant. Do not use petroleum-based greases, which will degrade polyurethane over time. Professional installation recommended. Inspect the steering rack itself for wear or leaks before installing new bushings — new bushings will not correct issues with a worn or damaged rack.
