2012 Toyota Mark X Steering Bushes — Purpose, Service Tips, and When to Replace

Based on Toyota’s GRX13# repair manual procedures for the steering gear, the Toyota Electronic Parts Catalogue (which lists “bushing, steering gear” for this platform), and common aftermarket catalogues that supply rack-mount bush kits for the GRX130 series, the 2012 Toyota Mark X is fitted with steering bushes. The model runs a rack-and-pinion steering setup (with electric assist on most trims), and the steering gear is mounted to the front subframe via rubber bushes to isolate vibration and maintain alignment under load.

In this Mark X, steering bushes do the quiet, unglamorous work: they cushion the steering rack, keeping steering feel tight while filtering out harshness from rough Kiwi and Aussie roads. When these bushes age, harden, or tear, the steering can feel a bit vague off-centre, there may be a light clunk on turn-in or over speed humps, and tramlining can creep in as the rack shifts slightly under load.

As part of regular servicing, workshops typically inspect the steering rack mounting bushes along with tie rod ends and the intermediate shaft. There’s no fixed replacement interval—condition matters more than kilometres—but a visual check at each service and a proper lever/hand test at around 20,000–30,000 km is sensible. Any play at the rack mounts, visible cracking, or oil-soaked rubber (from past leaks) is a cue for replacement.

Replacement is straightforward for a qualified tech: the rack is supported, the brackets are removed, and the old bushes are pressed out and replaced with OE-style rubber or quality polyurethane, depending on the customer’s preference for comfort versus steering precision. After refit, a wheel alignment is recommended, as even a small change in rack position can alter toe and on-centre feel.

Owners who value a supple, quiet ride frequently stay with OE rubber. Drivers chasing a sharper turn-in and better feedback might opt for polyurethane bushes, noting a mild increase in road feel. Whichever way it’s done, fresh bushes bring back that planted front-end feel and tidy up steering response. It’s a modest job that pays off every time the wheel is turned.

• Typical signs to watch: clunks over bumps, steering wander, inconsistent return-to-centre, and uneven tyre wear.
• Best practice: inspect at each service, replace in pairs, and align the vehicle afterwards.

Popular questions about 2012 Toyota Mark X steering bushes

Do all 2012 Mark X models have steering rack bushes?
Yes. Across the GRX13# series, the steering rack mounts to the front crossmember with rubber bushes. Variations in power assist don’t remove the need for these mounts, so every 2012 Mark X will have them.

What are the symptoms of worn steering bushes on a Mark X?
Drivers often report a light knock over sharp bumps, slight vagueness around centre, and sometimes a pull or tramlining on coarse roads. Visual inspection may show cracked or perished rubber, and technicians may detect rack movement when the steering is rocked.

Should the wheel alignment be checked after replacing steering bushes?
Absolutely. Even if the tie rods weren’t disturbed, the rack can sit fractionally differently once the new bushes are in. A post-repair alignment ensures toe is on the money and steering feel is consistent.
