Parts for your 2009 Lexus Is-Steering bushes

2009 Lexus IS steering bushes — purpose, care and when to replace

The 2009 Lexus IS (XE20 series) runs a rack-and-pinion steering setup, and it does use steering bushes. In Lexus/Toyota factory repair information and the Toyota Electronic Parts Catalogue for the XE20, the steering rack is shown mounted to the front subframe via rubber isolator bushes, with additional bush elements in the column’s lower joint. These bushes isolate noise and vibration, keep the rack securely located, and help deliver that tidy on‑centre feel drivers expect from a Lexus.

On this model, the steering rack bushes take up the load between the rack housing and the front crossmember. Over time, heat, oil contamination and big bumps can soften or crack the rubber. When wear sets in, the driver might notice a light knock over sharp edges, a vague or wandering feel at motorway speeds, or a small delay before the car responds to steering inputs. Left long enough, it can chew out tyres and take the shine off the IS’s sharp handling.

Replacement is straightforward workshop work: the rack is supported, old bushes are pressed or pried out, and new OEM or quality polyurethane items are fitted before the rack is re-torqued to spec. It’s good practice to:

• Inspect for play with the car on a hoist while an assistant nudges the wheel left-right.
• Check for oil leaks from the engine or power steering lines that may have softened the rubber.
• Replace bushes as a set and book a wheel alignment afterwards.

As part of routine servicing, a visual check of the rack mounts, the steering column lower joint bush, and adjacent suspension bushes keeps the steering tight. City cars that cop potholes and speed humps, or vehicles that see rough rural roads, may need bushes sooner. For many owners, a fresh set around the 120–160,000 km mark restores the crisp feel they remember. Poly bushes can sharpen response and resist oil, while OEM rubber keeps NVH closest to factory — either way, quality parts and correct torque are key. If there’s still a knock after bush replacement, have the technician check inner tie rods, lower control arm rear bushes, and the intermediate shaft for play.

FAQs

Do all 2009 Lexus IS models have steering rack bushes?
Yes. The XE20-series IS uses rubber isolator bushes to mount the steering rack to the front subframe. They’re a normal wear item and can be replaced without changing the whole rack if the rack itself is healthy.

What are the common signs the steering bushes need replacing?
Drivers often notice a light clunk over bumps, a vague on‑centre feel, or slight steering wander. Uneven front tyre wear and a dull thud when shifting from drive to reverse can also point to movement at the rack mounts.

Should the car be aligned after replacing steering bushes?
It’s a good idea. Even if toe hasn’t moved much, refitting and torquing the rack can subtly change geometry. A quick alignment locks in straight-line stability and protects tyres.
