Parts for your 2014 Lexus Is-Steering bushes

2014 Lexus IS steering bushes — are they actually a thing?

For the 2014 Lexus IS (XE30 series: IS 250, IS 350, IS 300h), “steering bushes” aren’t a separate, serviceable item. Technical references including the Lexus IS (XE30) Repair Manual (Steering – Electric Power Steering), the Lexus New Car Features manual for XE30, and the Lexus Electronic Parts Catalogue for GSE/AVE models show an electric power steering (EPS) rack-and-pinion unit that bolts directly to the front subframe. There are no standalone steering rack bush kits listed, any isolating elements are integral to the steering gear assembly and supplied only with a replacement rack.

Why did Lexus do this? The EPS rack in the XE30 is engineered for direct, precise feel. To achieve that, the rack housing is rigidly mounted to the crossmember rather than floating on large rubber cushions. Noise, vibration and harshness (NVH) are controlled elsewhere in the chassis (subframe mounts, control arm bushes, and column joints), so there’s no need for separate, serviceable “steering bushes” in the traditional sense. That’s why generic “steering bush” kits you’ll see for older models don’t apply to a 2014 IS.

What should owners look at if the steering feels vague or there’s a knock on corrugations? The usual suspects are:

• Inner and outer tie-rod ends (play here feels like rack wear)
• Front lower control arm bushes and ball joints (compliance bush movement mimics steering slop)
• Front strut top mounts/bearings and sway bar link/bushes (noises over bumps)
• Intermediate steering shaft/universal joint (notchy feel or free play)
• Wheel alignment and tyre condition/pressures (tramlining or mid-corner push)

If free play is confirmed inside the rack itself, Lexus documents specify replacing the complete steering gear assembly rather than pressing in new bushes. During servicing, it’s sensible to check rack-to-subframe fastener torque, inspect boots for leaks or tears, and confirm EPS calibration or fault codes if the steering effort feels off. Genuine parts and proper alignment procedures keep the steering feel crisp and consistent, just as Lexus intended.

Does the 2014 Lexus IS have steering rack bushes?

No. The XE30 EPS rack is rigidly mounted to the subframe, and Lexus does not list separate, serviceable rack bushings. Any isolators are part of the rack assembly and come only with a replacement unit.

What should be serviced instead if the steering feels loose?

Start with inner/outer tie-rod ends, front control arm bushes, ball joints, sway bar links/bushes, strut top mounts, and the intermediate shaft joint. Check wheel alignment and tyre condition too. If internal rack play is found, the correct fix is replacing the steering gear assembly.

Can aftermarket polyurethane steering rack bushes be fitted to a 2014 IS?

Generally no. The vehicle isn’t designed for separate rack bush inserts, and most reputable catalogues don’t list a kit for the XE30. Fitting improvised bushes risks misalignment and higher NVH. If a supplier claims fitment, verify against Lexus documentation before buying.
