Parts for your 2001 Toyota Crown-Suspension bushes

2001 Toyota Crown suspension bushes — what they do and how to look after them

Based on Toyota’s technical literature, suspension bushes are absolutely used on the 2001 Toyota Crown (S170 series). The Toyota Crown S170 New Car Features (NCF) manual describes double-wishbone front suspension and multi-link rear layouts, both of which rely on rubber-isolated arm pivots. The Toyota Electronic Parts Catalog (EPC) lists multiple bushes for front and rear control arms, subframe mounts and stabiliser (sway) bars across JZS171/JZS173/GS171 variants. The S170 Repair Manual also details inspection and replacement of arm and stabiliser bar bushes. So, suspension bushes are relevant and fitted to this vehicle.

On the 2001 Crown, bushes sit between suspension arms, the subframe and the body to isolate noise, vibration and harshness while keeping wheel alignment stable under braking, cornering and bumps. They’re the quiet achievers that help the big Toyota feel planted and refined on Kiwi and Aussie roads. Over time, the rubber can crack, harden, or tear, leading to sloppy steering, clunks over speed humps, tyre feathering and braking shimmy.

Good servicing practice is to inspect bushes at every service or at least every 20,000–30,000 km, and during WOF/rego checks. Look for perished rubber, split voids, off-centre sleeves, and oil contamination from leaking shocks or power steering fluid. Pay close attention to front lower control arm bushes, rear multi-link inner bushes and stabiliser bar D-bushes and links.

• When to replace: if there’s visible cracking/tearing, excessive movement with a pry bar, or persistent NVH and alignment drift.
• What to fit: quality OEM-style rubber keeps the Crown’s comfort, polyurethane tightens response but can add NVH. Many owners favour OEM rubber for daily use.
• Do it in pairs: left and right together maintains symmetry.

On this model, some front and rear arm bushes can be pressed in, but complete arm assemblies are often cost-effective when ball joints are also tired. If pressing bushes, use the correct drifts, align any moulded index marks, and only final-torque pivot bolts at normal ride height to avoid preloading the rubber. After any bush or arm replacement, a wheel alignment is a must to bring caster, camber and toe back to spec.

Handy extras: refresh stabiliser bar D-bushes and link rods when chasing knocks, check subframe mounts, and replace any stretched eccentric bolts. A light smear of anti-seize on bolt shanks (not on rubber) helps the next round of spanner work. Always follow Toyota’s torque specs from the S170 Repair Manual.

How can someone tell if the 2001 Toyota Crown’s suspension bushes are worn?

Common giveaways are clunks over potholes, vague steering on the motorway, shimmy under brakes and uneven tyre wear. Visually, cracked or torn rubber, or sleeves sitting off-centre, are red flags. A pry-bar test showing excessive arm movement also points to tired bushes.

If symptoms persist after tyre balance and shock checks, inspect the front lower control arm bushes, rear multi-link inner bushes and the sway bar D-bushes first, as these cop the most grief on local roads.

Should the 2001 Crown use OEM rubber or polyurethane bushes?

For daily driving and that classic Crown refinement, OEM-style rubber is the safe bet. It controls geometry well while keeping NVH low. Polyurethane sharpens steering and response, handy for spirited driving, but it can transmit more road feel and may creak if not greased where applicable.

Mix-and-match works too: OEM rubber for control arms and poly for stabiliser bar D-bushes to trim roll without spoiling ride quality.

Is a wheel alignment required after replacing bushes on a 2001 Toyota Crown?

Yes. Any change to arm bushes or complete arms affects caster, camber and toe. A professional alignment straight after the work prevents rapid tyre wear and restores straight-line stability and steering feel.

Ask the shop to torque pivot bolts at ride height before aligning, then set camber/caster (where adjustable) and toe to Toyota’s S170 specs.
