2012 Toyota Crown steering bushes: what they do and when to replace them

Based on technical sources such as Toyota’s Electronic Parts Catalogue and the factory Repair Manual for the 2012 Crown (S200/S210 generation), the vehicle uses a rack-and-pinion steering gear mounted to the front crossmember with rubber “insulators” — commonly called steering rack mounting bushes. That means steering bushes are fitted and directly relevant to servicing this model, whether it’s running hydraulic or electric power steering.

Steering bushes on a 2012 Toyota Crown sit between the steering rack and the front subframe, acting as small but critical cushions. Their main job is to keep the rack precisely located while soaking up vibration and road harshness, so the wheel feels planted without buzz through the column. By controlling the rack’s position under load, the bushes help maintain toe stability, which protects tyres and preserves that tidy Crown tracking feel at motorway pace.

When these rubber insulators age, harden, or tear, the rack can shift a fraction. Typical signs include a dull clunk over sharp bumps, a vague or wandering feel on centre, light knock when rocking the wheel at a standstill, and accelerated inner edge tyre wear. On hydraulic variants, leaking power steering fluid can soften the rubber and hasten failure, on EPS cars, heat and ozone are the usual culprits.

Good practice is to inspect the bushes at every service, especially from 80,000 kilometres onwards, or sooner if the car sees rough roads. A technician will lever the rack gently to check for movement, look for cracking or separation of the rubber, and confirm the mounting bolts aren’t backing off. Any slack means replacement as a pair, left and right.

Replacement is straightforward workshop work: support the rack, remove the mounting brackets and bolts, swap the bushes in the correct orientation, then tighten everything to spec and perform a wheel alignment. Using quality OEM-equivalent rubber keeps refinement, firmer polyurethane can sharpen response but may add vibration, which doesn’t suit every Crown. Avoid mixing different bush types side to side.

While you’re there, inspect the intermediate shaft joints and tie rod ends, and check for fluid seepage on hydraulic racks. After fitting, road-test over corrugations and through a steady lane-change, confirming the steering recentres cleanly and stays true. Keeping the steering bushes fresh is a modest-cost way to restore crisp response and protect tyres, making it a smart inclusion on any major service. If the car runs wider aftermarket wheels or sees repeated potholes, shorten inspection intervals, because higher loads accelerate bushing deformation and noise and wear.

Popular questions about 2012 Toyota Crown steering bushes

What are the common symptoms of worn steering bushes on a 2012 Crown?

Owners often notice a dull clunk over potholes, a slight knock when rocking the wheel at a standstill, or a vague on‑centre feel. You might also see quicker inner edge tyre wear because the rack can shift under load, nudging toe settings around.

Similar noises can come from lower control arm bushes or tie rod ends, so a proper inspection is the go before ordering parts.

How often should the steering bushes be replaced?

There’s no fixed interval. Have them checked at every service from about 80,000 kilometres, and earlier if the car lives on coarse-chip roads or sees heavy urban speed humps. Replace when there’s visible cracking, delamination, fluid damage, or measurable rack movement.

Always do a wheel alignment after replacement to lock in straight-line stability and even tyre wear.

Can polyurethane steering rack bushes be used on a Crown?

Yes, but pick your priorities. Poly bushes can sharpen steering feel and response, which keen drivers appreciate. The trade-off is extra vibration and a touch more cabin buzz, particularly noticeable on coarse Aussie and Kiwi roads.

If comfort and refinement are top of the list, quality OEM-style rubber is a safe bet. Whatever you choose, replace bushes as a matching pair and confirm correct fitment for the specific Crown series.
