Parts for your 2004 Toyota Highlander-Steering bushes

2004 Toyota Highlander steering bushes — fitment, purpose, and service advice

Based on Toyota’s service literature for the XU20 Highlander (2001–2007) and listings in the Toyota Electronic Parts Catalog, the 2004 Toyota Highlander uses a rack-and-pinion steering gear mounted to the front subframe with rubber mounting bushes. There’s no separate steering box on this model, and the intermediate shaft uses universal joints rather than a rubber coupler. So “steering bushes” are relevant to this vehicle — they’re the rack mounting bushes that locate the steering rack and help keep steering feel tight and quiet.

Those steering bushes do a deceptively big job. They cushion vibration, keep the rack centred under load, and reduce harshness coming up through the wheel. When they age, soften from power-steering fluid exposure, or crack, owners may notice clunks over bumps, vague on-centre feel, tramlining, or a light knock when turning at parking speeds. Toyota’s Repair Manual procedures for rack installation and the EPC both show these bushes as serviceable items, so they can be replaced without changing the entire rack if the housing and seals are sound.

For routine servicing, it’s smart to have the bushes inspected during front-end checks — say every 20,000–40,000 km or whenever tyres are rotated, aligned, or when a power-steering leak has been present. If the rack has leaked, sort the leak first, PS fluid can swell rubber and fast-track bush failure. When replacing, owners can choose genuine-style rubber (quiet, OE feel) or quality polyurethane (sharper response, a touch more NVH). Either way, use new hardware if specified in the workshop manual, and torque the rack mounts with the vehicle at normal ride height to avoid pre-loading the bushes.

Because the rack position can shift slightly when the mounts are loosened, a post-job wheel alignment check is good practice, even if tie-rods weren’t disturbed. Expect around 1–2 hours’ labour depending on access and corrosion. If subframe bolts are touched, support the assembly properly — this isn’t a spot to wing it. A tidy set of fresh steering bushes will restore that confident, direct feel Highlander owners expect, keeping the family bus pointing straight on Kiwi and Aussie roads alike.

• Tell-tales they’re due: knocking over speed humps, wandering at highway speeds, shimmy under light braking, or visible cracks/softness in the bush material.
• Best practice: fix leaks first, pick the right bush material for the use case, and get an alignment check after fitment.

FAQs

Does a 2004 Toyota Highlander actually have steering bushes?
Yes. It uses rubber bushes to mount the rack-and-pinion steering gear to the subframe. These are serviceable without replacing the whole rack if the steering gear itself is in good condition.

How often should the steering bushes be checked or replaced?
Have them inspected during regular front-end checks every 20,000–40,000 km, or sooner if there’s a power-steering leak, clunks, or vague steering. Replacement is condition-based — change them when cracked, oil-soaked, or if free play is evident.

Should owners choose OEM rubber or polyurethane bushes?
OEM-style rubber keeps it quiet and comfy, ideal for daily driving. Polyurethane can sharpen response and durability, which some drivers prefer, but it may add a little more road feel and noise. Both are fine when fitted correctly and torqued at ride height.
