Parts for your 2013 Lexus Is-Steering rack

2013 Lexus IS steering rack — what it does and how to look after it

Yes, a steering rack is absolutely used on the 2013 Lexus IS. Lexus technical literature for the second‑generation IS (XE20) — specifically the Steering (ST) section of the Lexus IS250/IS350 Repair Manual — identifies a rack‑and‑pinion steering gear, with electric power assist on most variants. Toyota’s Electronic Parts Catalog (EPC) also lists a “Steering Gear Assembly” for 2013 IS models, confirming the part’s presence and serviceability. So, a steering rack is relevant to the 2013 Lexus IS and is a normal service item when wear or damage occurs.

On this model, the steering rack converts the driver’s wheel input into precise movement at the front wheels, giving that tight, direct feel the IS is known for. Most 2013 IS grades run electric power steering (EPS), where an electric motor assists the rack, there’s no power‑steering fluid to top up. In some markets or specific trims, you may encounter hydraulic assist, which adds fluid and hoses to the picture — the checks below still apply, with leak inspections added if hydraulic.

As part of regular servicing, a technician should:

• Inspect rack boots (bellows) for splits and any grease or fluid contamination.
• Check inner and outer tie‑rod ends for play, noise, or torn dust covers.
• Verify rack mounting bushes are secure and not perished.
• Confirm steering effort and return to centre feel are normal, scan for EPS fault codes if warning lights are on.
• If hydraulic assist is fitted, check for leaks and correct fluid level and condition.

Common symptoms of a tired rack include a clunk over bumps, a dead zone around centre, wandering, uneven tyre wear, a knocking through the column, or (on hydraulic) visible leaks. If any of these are present, replacement or overhaul is on the cards.

When replacing the rack, it’s smart to fit new inner and outer tie rods and fresh boots at the same time. On EPS‑equipped cars, the steering angle/torque sensor zero‑point should be calibrated with a scan tool after installation. The subframe and rack bolts must be torqued to spec, and a wheel alignment is non‑negotiable. Genuine or quality remanufactured racks are recommended to keep steering feel crisp and consistent. Expect several hours’ labour plus an alignment, it’s a good opportunity to assess lower control arm bushes and ball joints while it’s all under the bonnet.

• Does the 2013 Lexus IS have a steering rack?
  Yes. Lexus repair manual procedures and the Toyota EPC both list a rack‑and‑pinion “Steering Gear Assembly” for 2013 IS variants, so the rack is a core part of the car’s steering system.
• Is there power‑steering fluid to change on a 2013 IS?
  Most 2013 IS models use electric power steering, so there’s no fluid service. If a specific market trim uses hydraulic assist, follow the owner’s manual and the reservoir cap specification for the correct fluid and service interval, and inspect for leaks during routine servicing.
• What are the signs the rack needs attention?
  Play in the wheel, pulling or wandering, uneven tyre wear, clunks over bumps, stiffness or not returning to centre, EPS warning lights, or visible leaks (hydraulic). Any of these warrant a professional check and likely rack, tie‑rod, or bushing work plus alignment.
