Parts for your 2015 Mitsubishi Outlander-Steering bushes

2015 Mitsubishi Outlander steering bushes — what they do and when to replace

Referencing the Mitsubishi Outlander (ZJ/ZK, 2013–2015) Service Manual, Group 37 Steering, and the Mitsubishi ASA parts catalogue, the 2015 Outlander uses rack-and-pinion electric power steering mounted to the front crossmember via insulator bushings (commonly called steering bushes). Aftermarket technical catalogues from brands like Whiteline and SuperPro also list steering rack–mount bush kits for this model. So yes — steering bushes are fitted and relevant on a 2015 Mitsubishi Outlander.

These bushes sit between the steering rack housing and the subframe, isolating noise and vibration while keeping the rack precisely located. Good bushes help the Outlander track straight, give a consistent on-centre feel, and prevent clunks over bumps. They’re small bits of rubber (or polyurethane, if upgraded), but they play a big role in both comfort and steering accuracy.

As part of regular servicing, it’s smart to inspect the bushes every 20,000–30,000 kilometres or annually. A technician will look for cracking, compression set, elongation of the sleeve holes, and any rack movement when the steering is rocked. Oil contamination and harsh road use can speed up wear.

Common signs the steering bushes are tired include:

• Clunks or knocks from the front when turning or hitting potholes
• Vague on-centre steering, tramlining, or wander at highway speeds
• Uneven or accelerated front tyre wear despite correct pressures
• Visible rack shift on the subframe when a helper turns the wheel

Replacement is straightforward for a workshop: the rack is supported, mounting bolts are removed, and the old bushes are pressed out and new ones installed, then everything is torqued to the service manual spec. A wheel alignment is recommended afterwards, and with electric power steering, a steering angle/centering calibration may be required using a scan tool. Owners can choose OEM-style rubber for comfort or polyurethane for a firmer, more direct feel. If the Outlander has higher kilometres, it’s worth checking inner/outer tie rods and lower control arm bushes at the same time to keep the front end tight and WOF-ready. Avoid petroleum-based lubricants on rubber, and have the fasteners rechecked after a few hundred kilometres if polyurethane is fitted.

Popular questions about 2015 Mitsubishi Outlander steering bushes

Do all 2015 Outlanders have steering bushes?
The ZJ/ZK Outlander uses an electric rack-and-pinion assembly mounted with insulator bushings. Whether it’s 2WD or AWD, those rack-mount bushes are part of the front subframe setup. Some OEM bushes are sold with the rack, but quality aftermarket options allow bush-only replacement.

How long do the bushes typically last?
There’s no fixed interval, but many see 80,000–150,000 km depending on roads, loads, and heat. Inspect them at each service. If there’s clunking, vague steering, or a WOF advisory for play, plan a replacement and a follow-up alignment.

Rubber or polyurethane — which is better?
Rubber keeps the Outlander quiet and comfy, ideal for daily driving. Polyurethane sharpens steering response and resists deformation, handy for towing or spirited driving. Expect a touch more road feel with poly. Both are fine when installed and torqued correctly.
