Parts for your 2016 Lexus Is-Steering bushes

2016 Lexus IS steering-bushes — are they actually a thing?

For the 2016 Lexus IS (XE30 series), “steering-bushes” aren’t a service item and, in practical terms, aren’t used the way many older hydraulic power steering setups were. Technical references including the Lexus IS Repair Manual for the XE30 platform (Power/Electric Power Steering sections), the Lexus/Toyota Electronic Parts Catalogue (EPC, Steering Gear & Linkage group), and supplier catalogues from Nolathane and SuperPro all show no serviceable steering rack mounting bushes listed for this model year. The steering gear is an electric power steering (EPS) rack that’s rigidly mounted to the front subframe, and any compliance is managed elsewhere in the suspension rather than through rack bushes.

Manufacturers moved away from rack-mounted rubber bushes on many late‑model EPS vehicles to improve steering precision and road feel. On the 2016 IS, Lexus targets sharp, consistent steering by bolting the rack solidly, then tuning NVH and compliance with other components (for example, lower control arm bushes, strut mounts, and sway bar bushes). The parts most likely to cause looseness, knocks, or vagueness in the steering on this car are tie‑rod ends (inner/outer), the intermediate shaft universal joint, front lower control arm rear bushes, and sway bar links/bushes—rather than any “steering-bushes” at the rack.

Key technical takeaways from those sources:

• EPS rack is designed to mount rigidly to the front suspension member, with no separately serviceable rack mounting bushes shown in the Lexus EPC for 2016 IS variants.
• The Lexus Repair Manual lists replacement procedures for the rack assembly, tie rods, column/shaft components, and related fasteners—but not rack bushes as a standalone part.
• Major aftermarket bushing catalogues do not offer steering rack bush kits for the XE30 IS, reinforcing that a replaceable “steering-bush” isn’t part of the platform design.

So, if there’s a clunk, shimmy, or on‑centre wander, it’s worth having a technician check tyre condition and pressures, wheel alignment, tie‑rod ends, the intermediate shaft joint, lower control arm rear bushes, sway bar links/bushes, and strut top mounts. Those spots are the usual suspects on a 2016 IS, not a missing or worn “steering-bush”.

Popular questions

Does a 2016 Lexus IS have steering rack bushes that need replacing?
No. The EPS rack is rigidly mounted and the Lexus parts catalogue doesn’t list separate rack bushes for this model year. If the steering feels loose or knocks over bumps, look to tie‑rod ends, the intermediate shaft joint, front control arm bushes, sway bar links/bushes, and alignment first.

What should be checked if the steering feels vague on a 2016 IS?
Start with tyres and alignment, then inspect outer and inner tie‑rod ends, the steering intermediate shaft universal joint, and the front lower control arm rear bushes. Strut top mounts and sway bar links/bushes can also contribute to noise and play.

Can aftermarket steering-bushes be added to improve feel?
Not recommended. The rack on the 2016 IS isn’t designed for add‑on bushes, and retrofitting them can increase NVH or stress the housing. Better gains come from ensuring suspension bushes are healthy, tyres are quality and correctly inflated, and alignment is set to factory spec for local roads.
