Parts for your 2003 Mitsubishi Lancer-Steering bushes

2003 Mitsubishi Lancer steering bushes — what they do and when to replace them

Steering bushes are absolutely used on the 2003 Mitsubishi Lancer. Technical references including the Mitsubishi Lancer Workshop Manual (2002–2007, Group 37 – Steering), the Mitsubishi ASA electronic parts catalogue for CG/CH models, and mainstream repair guides such as the Haynes Lancer manual all show the steering rack mounted to the front crossmember via rubber insulator/bushes. These components isolate vibration, control steering rack movement, and help maintain consistent steering geometry.

On this Lancer, the key “steering bushes” are the rack-and-pinion mounting bushes. They’re designed to cushion the rack, cut down noise and harshness, and stop the rack shifting under load. When they age, harden, or split, the rack can move slightly on the subframe, which shows up as vague on-centre feel, a knock over sharp bumps, or a clunk as the wheel’s turned at low speed. Drivers may also notice tramlining or a need for frequent small corrections on the motorway. While control-arm bushes affect handling too, they’re suspension items—steering rack bushes specifically manage the rack’s location.

As part of regular servicing, it’s smart to visually check the rack bushes for cracks, oil swelling (from power steering leaks), and excessive movement while a helper turns the wheel. Any play or perished rubber is a cue to replace. Many owners choose OEM-style rubber for comfort, others go for quality polyurethane for sharper response and durability—especially if the car runs wider tyres or sees spirited driving. Either way, replacing tired bushes and then getting a proper wheel alignment will tidy up steering feel nicely.

Replacement is straightforward for a competent technician: safely support the car, mark the rack position, support the rack body, swap the bushes, and torque all fasteners to spec from the workshop manual. It’s also worth inspecting tie rod ends and the lower column joint at the same time, plus addressing any power steering fluid leaks that could attack new rubber. Most daily-driven Lancers benefit from bush inspection at service intervals and replacement somewhere in the mid to high six-figure kilometre range, depending on road conditions and tyre load.

• Typical signs: clunk/knock over bumps, vague steering, rack “shift” sensation
• Good practice: replace in pairs, use quality bushes, finish with a wheel alignment
• Comfort vs performance: OEM rubber for NVH, polyurethane for precision and longevity

Popular questions about 2003 Mitsubishi Lancer steering bushes

How can someone tell if their Lancer’s steering rack bushes are worn?
They’ll often feel looseness on-centre, a thud or knock turning at low speeds or over potholes, and a small “kick” through the wheel as the rack shifts. A technician can confirm by watching the rack while the wheel’s turned—any visible rack movement on the subframe suggests the bushes are past it. Also check for power steering fluid leaks that may have degraded the rubber.

Is it worth upgrading to polyurethane steering rack bushes?
For a daily commute chasing comfort, fresh OEM-style rubber is spot on. If sharper steering feel and longevity are the goals—especially with bigger wheels/tyres—quality polyurethane bushes offer firmer location and better resistance to oil and heat. Expect a touch more road feel through the wheel with poly, which many enthusiasts actually prefer.

Do steering rack bushes need wheel alignment afterwards?
Yes. Any time the rack is disturbed or mounting hardware is loosened, a wheel alignment is recommended. It ensures toe settings are bang on and the steering wheel sits straight, making the most of the new bushes.
