Parts for your 2017 Mazda Bt-50-Steering bushes

2017 Mazda BT-50 steering-bushes: what they do and when to replace

Steering-bushes are relevant and used on the 2017 Mazda BT-50. Technical references including the Mazda BT-50 UR Workshop Manual (Steering System – Rack-and-Pinion Power Steering), the Ford Ranger PX platform service literature (shared T6 architecture), and the Mazda Electronic Parts Catalogue for the UR series confirm a hydraulic rack-and-pinion steering gear mounted to the front crossmember using rubber mounting insulators/bushes. There’s no idler arm on this model, instead, the rack is secured with serviceable mounting bushes that control movement and isolate vibration.

On the BT-50, the steering-bushes sit between the steering rack housing and the subframe. Their job is to absorb vibration, keep the rack properly located under load, and maintain precise tie-rod geometry. When those bushes soften, split, or flog out—often from kilometres on corrugations, heavy towing, bigger tyres, or oil contamination—the rack can shift slightly. That shows up as vague steering on centre, a thud over sharp bumps, kickback through the wheel, or the ute wandering on the highway.

As part of routine servicing, it’s smart to:

• Inspect the steering-bushes for cracks, deformation, or oil swelling, and check for rack movement while a helper rocks the steering wheel.
• Listen for clunks on take-off or when backing off the throttle—movement at the rack mounts is a giveaway.
• Note uneven or rapid tyre wear that persists after correct pressures and a wheel alignment—excess compliance at the rack mounts can be a root cause.

If replacement’s due, a competent tech will support the rack, remove the mounting hardware, swap the bushes, and torque everything to factory spec. It’s a straightforward job on a hoist, but access can be tight. A wheel alignment is recommended afterwards, especially if the rack has been shifted. Where you can, avoid prying on the rack boots and keep power steering fluid and engine oil off new rubber bushes—petroleum exposure shortens their life.

Owners can choose quality OEM-style rubber for comfort and isolation, or reputable polyurethane aftermarket options (common in AU/NZ) for sharper steering feel and better durability off-road. Rubber generally rides quieter, polyurethane tends to hold alignment better under load. For utes that see tradie work, trailers, or beach runs, checking the steering-bushes every 40,000–60,000 km—or at least annually—helps keep the BT-50 pointing straight and the tyres wearing evenly.

Popular questions about 2017 Mazda BT-50 steering-bushes

What are the signs the BT-50’s steering-bushes are worn?
Common signs include a dull clunk over potholes, a shimmy or kickback through the wheel, vague on-centre feel, and the ute drifting on cambered roads. You might also see uneven tyre wear that doesn’t improve after a proper alignment.

Do polyurethane steering-bushes make the ride harsh?
Polyurethane tightens steering response and can transmit a touch more road feel. On most BT-50s it’s still perfectly civil on-road, but rubber is usually a tad quieter over small chatter. Choice comes down to comfort preference versus durability and precision.

Do I need a wheel alignment after replacing steering-bushes?
It’s wise to get one. The rack can shift slightly during the job, and fresh bushes can change how the rack sits under load. A quick alignment helps protect tyres and restores straight-ahead feel.
