Parts for your 2004 Toyota Kluger-Steering bushes

2004 Toyota Kluger steering bushes — what they do and when to replace them

Steering bushes are absolutely relevant to the 2004 Toyota Kluger (XU20). Toyota’s factory repair manual for the 2004 Kluger/Highlander (Steering—Power Steering Gear) specifies a rack-and-pinion steering gear mounted to the front subframe using rubber “cushions”/bushes and brackets. The Toyota Electronic Parts Catalogue also lists “Cushion, Steering Gear” for this model, and reputable aftermarket catalogues in Australia and New Zealand (e.g., Nolathane and SuperPro) offer steering rack mounting bush kits for the 2001–2007 Kluger/Highlander. That all confirms the vehicle uses steering rack bushes.

On this Kluger, the steering bushes isolate the rack from the body, keeping the steering gear correctly located while filtering out vibration and road shock. When they’re healthy, steering feels tight and linear, with minimal kickback. As the original rubber ages—especially if exposed to power steering fluid leaks—it softens, allowing the rack to shift under load. That can show up as vague steering, a clunk over bumps, or the wheel needing small corrections to hold a straight line.

• Common signs of worn bushes: clunk/knock over sharp bumps, wandering on the motorway, shudder or nibble on turn-in, and visible cracking or oil-soaked rubber at the rack mounts.

As part of routine servicing, it pays to inspect the rack mounts for cracks, separation, or fluid contamination. The 2004 Kluger runs a hydraulic power steering system, leaks from lines, pump, or rack seals can degrade the rubber, so fix any seepage and use the correct fluid before fitting new bushes.

Replacement options are typically OEM-style rubber (quiet, factory feel) or polyurethane (firmer, crisper steering, potentially a touch more NVH). Either is fine for daily use, those wanting sharper response often choose poly, while family haulers may prefer rubber.

1. Support the rack safely and remove the rack-to-subframe brackets and old bushes.
2. Clean the mounting surfaces, then install new bushes in the correct orientation.
3. Refit brackets and torque fasteners with the vehicle at normal ride height to avoid pre-loading.
4. Finish with a wheel alignment, even small rack movements can alter toe.

Most workshops can handle this in about 1–2 hours. If there’s still play after new bushes, check inner/outer tie rod ends and the intermediate steering shaft joints. Keeping the mounts fresh and the system leak-free goes a long way to restoring that positive Kluger steering feel.

Popular questions about 2004 Toyota Kluger steering bushes

Are steering rack bushes the same as control arm bushes on a 2004 Kluger?
No. Steering rack bushes locate and isolate the steering gear itself, while control arm bushes locate the suspension arms. Both can cause clunks or vague handling when worn, but they live in different spots and do different jobs. A proper inspection will pinpoint which set is making the noise or causing the wander.

How long do Kluger steering rack bushes last, and what does replacement typically involve?
It varies with driving and exposure to leaks, but many original bushes show wear by 150,000–250,000 km. Replacement is usually a straightforward rack-in-car job with basic hand tools, taking around 1–2 hours for an experienced tech. After fitting, a wheel alignment is recommended.

Can worn steering bushes cause a WOF or roadworthy failure?
Yes, if they allow excessive rack movement or are oil-soaked and deteriorated. Assessors may note free play, knocking, or insecure mounting. Repairing leaks and replacing degraded bushes generally clears the issue.
