Parts for your 2007 Toyota Crown-Suspension bushes

2007 Toyota Crown suspension bushes: what they do and when to replace them

Suspension bushes are absolutely used on the 2007 Toyota Crown. Technical references including the Toyota Crown S180 series Repair Manual (GRS18# chassis, Chassis–Suspension sections) and the Toyota Electronic Parts Catalogue for GRS18# models list multiple bushes across the front double-wishbone and rear multi-link assemblies (e.g., control arm bushes, stabiliser bar bushes, subframe mounts, and trailing arm bushes). Aftermarket fitment catalogues for the S180 Crown also specify replacement bushes by location. So, for a 2007 Toyota Crown, suspension-bushes are fitted from factory and are a key service item.

On this luxury saloon, the bushes are the quiet overachievers. Pressed into control arms, sway bar mounts, and the rear cradle, they isolate noise and vibration while keeping the geometry tight for accurate steering and a plush ride. Each bush is essentially a rubber (or elastomer) cushion bonded to an inner and outer sleeve, allowing controlled flex as the suspension moves. When they age, the rubber cracks, softens, or separates, which introduces play you’ll feel as vagueness in the steering, knocking over bumps, or unstable braking. Tyre wear can creep in too, because the wheel alignment can’t hold spec when bushes are flogged out.

Regular servicing of a 2007-toyota-crown suspension-bushes setup is straightforward. A good rule of thumb is an inspection every 20,000–30,000 kilometres or annually, and any time new tyres are fitted or an alignment is done. Look for perishing, splits, oil contamination (from a weeping shock or engine leak) and torn sleeves. City commuting is kind, but rough rural roads, heavy loads, and hot climates in Aus and NZ can shorten bush life. Expect many original bushes to last 100,000–200,000 kilometres, with stabiliser bar bushes and high-load control arm bushes often going first.

When replacement time comes, torque all arm bolts at normal ride height to avoid pre-loading the new bushes. A wheel alignment afterwards is a must. Some locations allow individual bush replacement using a press, others are often done as complete arms for speed and reliability. Genuine-type rubber preserves the Crown’s refined NVH, while quality polyurethane can sharpen response at the cost of a firmer, sometimes noisier ride. If chasing comfort and WOF/RWC-friendly manners, stick with OE-style rubber in most positions and keep poly for sway bar mounts if a tad more roll control is wanted.

• Telltales: clunks on take-off or over bumps, tramlining, steering nibble, uneven inner/outer tyre wear, and wandering on the motorway.

Popular questions about 2007 Toyota Crown suspension bushes

How long do the bushes typically last?
On a well-kept Crown, many factory bushes will see 100,000–200,000 kilometres. Heat, rough roads, and oil leaks reduce that. Sway bar and front lower arm bushes usually age first, rear subframe mounts often last longer but are worth checking if there’s a dull thud from the rear.

Do they need to be pressed in, or can the whole arm be swapped?
Both are common. Some bushes are available separately and can be pressed in with the right tools. However, replacing complete control arms can save labour and ensures new ball joints too. Either way, an alignment is essential afterwards.

Rubber or polyurethane for a daily-driven Crown?
Rubber keeps the ride quiet and supple—ideal for daily and long-distance use. Polyurethane adds steering precision and roll control but can pass a bit more vibration into the cabin. Many owners mix and match: rubber in control arms, poly in sway bar mounts for a subtle handling lift without spoiling refinement.
