Parts for your 2012 Mitsubishi Outlander-Rack boots

2012 Mitsubishi Outlander Rack Boots: What They Do and When to Replace Them

Yes, the 2012 Mitsubishi Outlander uses steering rack boots. Technical sources including the Mitsubishi Motors Workshop Manual (2007–2013 Outlander, Group 37: Steering), the Mitsubishi ASA electronic parts catalogue for CW-series Outlander, and general repair guides such as the Haynes Outlander manual all depict a rack-and-pinion steering gear fitted with bellows-type rack boots (also known as steering rack gaiters).

On this Outlander, the rack boots sit at each end of the steering rack and act like flexible bellows. Their job is to keep grit, water, and road splash away from the rack bar and inner tie rods, while holding the correct lubrication and allowing full steering travel. If a boot splits, contaminants can chew out the inner tie rod and rack bearings, and on hydraulic systems it can even hide power-steering fluid leaks inside the boot.

As part of regular servicing, it’s smart to inspect the boots at every service interval (or roughly every 10,000–15,000 km). Age, UV, and off‑road use can crack the rubber. Once a boot shows tears or goes hard and brittle, replacement is the go. Many techs replace them in pairs to keep both sides in step.

• Common signs: visible cracking or splits, grease fling on the control arm, dampness from fluid inside the boot, a light knock on bumps, or uneven tyre wear from inner tie rod wear.
• Replacement tips: use quality boots and proper ear or screw clamps (not cable ties), lightly grease the inner lip, and make sure the boot isn’t twisted at full lock. If fluid pours out of a boot, the rack may need overhaul, not just a new boot.
• Alignment: removing the outer tie rod end is usually required, so a wheel alignment afterwards is recommended even if the threads were counted on removal.

A competent DIYer can handle rack boot replacement with the right tools, but for a daily driver heading to a WOF/regulatory inspection, getting a workshop to fit, torque to spec, and align the front end is a tidy option. Keeping the rack boots healthy is cheap insurance for steering feel, tyre life, and long-term rack longevity on a 2012 Outlander.

Does the 2012 Mitsubishi Outlander have rack boots?

Yes. It uses a rack-and-pinion steering gear with bellows-style rack boots (steering gaiters), as shown in the Mitsubishi Workshop Manual and ASA parts catalogue for CW-series Outlander.

How often should the rack boots be checked or replaced?

Check them at every service or 10,000–15,000 km. Replace if there are cracks, splits, or contamination inside. Many boots last 6–10 years, but harsh conditions can shorten that.

Do you need a wheel alignment after replacing rack boots?

Usually yes. Even if the tie rod end turns are counted, toe can still shift. A post-job alignment keeps steering straight and protects tyre wear.
