2015 Mitsubishi Lancer rack boots — what they do and when to replace them
Technical sources confirm the 2015 Mitsubishi Lancer uses steering rack boots (also called steering gear bellows or gaiters). The Mitsubishi Lancer (CJ/CF) Service Manual, Group 37 Steering, details inspection and replacement of the steering gear bellows, the Mitsubishi ASA electronic parts catalogue lists “bellows, steering gear” for 2015 Lancer variants, and the Haynes Repair Manual for Mitsubishi Lancer 2007–2017 likewise identifies rack-and-pinion bellows on these models. Whether fitted with electric power steering or hydraulic assist (market and trim dependent), the Lancer’s rack-and-pinion assembly uses protective boots over the inner tie rods and rack ends.
On a 2015 Lancer, the rack boots keep dust, water and road grit out of the inner tie rod joints and the rack shaft, helping preserve the rack seals and the smooth feel through the wheel. They also retain a dab of grease around the inner joints and allow the rack to move freely without contamination. If a boot splits or perishes, moisture and debris can chew out the inner tie rods and eventually the rack, turning a simple boot replacement into a pricey steering repair.
Rack boots aren’t a scheduled replacement item, but they’re worth inspecting at every service or WOF/reg/roadworthy check. Look for cracks, splits, loose or missing clamps, and any oil or fluid inside the boot (which can hint at a leaking rack seal on hydraulic systems). If a boot is damaged, it should be replaced promptly. Replacing a boot typically involves removing the outer tie rod end, sliding off the old boot, lightly greasing the inner joint per the service manual, then fitting the new boot with proper band clamps. Because the outer tie rod position is disturbed, a wheel alignment is strongly recommended to keep tyre wear even and steering true.
Good quality boots—OEM or reputable aftermarket—use ozone- and oil-resistant materials and proper ear or band clamps rather than generic cable ties. Fitted correctly, a fresh pair of rack boots is cheap insurance for the Lancer’s steering gear, especially if the car sees plenty of wet weather or unsealed roads across Australia or New Zealand.
- Inspect at each service (10,000–15,000 km): cracks, splits, loose clamps, fluid inside.
- Replace in pairs if one is perished, align the wheels afterwards.
- Avoid twisting the boot on install, use correct clamps and light approved grease.
Popular questions about 2015 Mitsubishi Lancer rack boots
Do all 2015 Lancers have rack boots?
Yes. All 2015 Lancer variants with rack-and-pinion steering (including models with electric or hydraulic assist) use protective bellows over the rack ends and inner tie rods. These are standard components noted in Mitsubishi’s factory service information and parts catalogues.
How can someone tell if a rack boot needs replacing?
Common signs include visible splits or cracks, a boot that’s loose on its clamp, or grease and grime packed inside. On hydraulic racks, fluid collecting in the boot can indicate a leaking internal seal. If any of these appear, plan a replacement and a follow-up wheel alignment.
Is it safe to drive with a torn rack boot?
It’s not ideal. While the car may still steer, a torn boot lets in water and grit that can quickly wear the inner tie rod and rack, leading to play in the wheel and uneven tyre wear. Replacing the boot early is far cheaper than a rack overhaul later.
