Parts for your 2007 Lexus Is-Suspension bushes

2007 Lexus IS Suspension Bushes

Suspension bushes are absolutely used on the 2007 Lexus IS. Technical references including the Lexus IS (GSE20/GSE21) workshop/repair manual for Chassis–Suspension, the Toyota Electronic Parts Catalogue (EPC) for the IS250/IS350, and well-known aftermarket catalogues (e.g., SuperPro and Whiteline listings for 2006–2012 Lexus IS) all document rubber/urethane bushes fitted to the front double-wishbone and rear multi-link assemblies. These include control arm bushes, stabiliser (sway) bar mounting bushes, end-link bushes, and various rear arm and subframe bushes.

On this generation IS, the bushes are the quiet achievers that keep the ride refined and the handling tidy. Pressed into the arms and brackets, they isolate noise, vibration, and harshness while still allowing precise, controlled movement of the suspension links. That’s why the IS feels planted in the bends yet calm over coarse-chip roads common across Australia and New Zealand.

Over time, heat, UV, road grime, and the odd pothole can crack or soften the rubber. When that happens, expect telltales like vague steering, a shimmy on braking, clunks over speed humps, or uneven tyre wear. A quick workshop check—levering the arms to spot excess play, inspecting for perished rubber, and listening for knocks on a road test—usually confirms it. The factory workshop procedures specify torque-at-ride-height for arm bolts, that step matters because tightening with the suspension hanging can preload and prematurely tear new bushes.

As part of routine servicing, it’s wise to inspect the IS’s suspension bushes every 20,000–30,000 km or annually, especially if the car sees rough rural roads or lots of stop-start city use. Front lower control arm rear bushes and front/rear stabiliser bar bushes are common wear items by 100,000–150,000 km. When replacing, quality OEM rubber restores the original luxury feel, while performance urethane can sharpen response at the cost of a touch more cabin NVH. Many bushes require a press, mixing left/right or incorrect orientation can cause alignment issues, so professional fitment is recommended.

• Watch for: clunks, tramlining, uneven tyre edges, steering kickback, wandering on the motorway.
• After replacement: get a full four-wheel alignment and recheck fastener torque after a few hundred kilometres.
• Pro tip: replace stabiliser bar bushes and end-links as a set to quieten creaks and improve roll response.

Looked after properly, fresh bushes bring the 2007 Lexus IS back to its best—quiet, composed, and confidence-inspiring on Kiwi backroads and Aussie highways alike.

Are worn bushes dangerous to drive on?

They can be. Mild wear usually shows up as vague steering or tyre scuffing, but severely cracked or separated bushes can affect braking stability and cornering predictability. If there are knocks, wandering, or rapid tyre wear, get it inspected promptly and avoid spirited driving until sorted.

How long do the factory bushes last on a 2007 Lexus IS?

It varies with climate and roads, but many owners see 100,000–150,000 kilometres from key bushes. Cars doing lots of city kerb hops or corrugated country kilometres may need them sooner, garaged, gently-driven examples often last longer.

Should they be replaced with rubber or polyurethane?

OEM-style rubber keeps the Lexus luxury feel and low cabin noise. Polyurethane tightens up steering and body control, which enthusiasts like, but can add a bit more vibration and squeak if not lubricated correctly. It comes down to comfort versus sharpness—both are valid choices.
