Parts for your 2008 Mitsubishi Outlander-Rack boots

2008 Mitsubishi Outlander rack-boots — purpose, care and when to replace

Based on technical references — the Mitsubishi Outlander 2007–2012 Factory Service Manual (Group 37: Steering) and the Mitsubishi ASA electronic parts catalogue for the CW-series — the 2008 Outlander runs a hydraulic rack-and-pinion steering gear that uses bellows-style rack-boots on both sides of the steering rack. So yes, rack-boots are fitted and absolutely relevant to this model.

On the 2008 Mitsubishi Outlander, rack-boots (also called steering rack gaiters) are tough rubber bellows that seal the inner tie rods and the rack ends from dust, water and grit. They help keep grease where it belongs and protect the rack’s inner seals, bushings and the joint on the inner tie rod. In Aussie and Kiwi conditions — heat, gravel, corrugations and the odd water crossing — intact boots are a quiet hero for steering longevity.

As part of regular servicing of a 2008 Outlander’s rack-boots, a quick inspection every service or 10,000–15,000 kilometres is smart. If a boot is cracked, perished, torn or looks wet with oil, it’s time to act. A torn boot lets in grit that can chew out inner tie rods and rack seals, if a boot is pooling with fluid, that can indicate an internal rack leak that needs further diagnosis.

When replacing, most workshops recommend doing both sides at once. A quality EPDM boot with proper stainless ear clamps is preferred over generic cable ties. During fitment, the outer tie-rod end is removed, the threads or length are marked to keep toe close, the new boot is slid on, seated in its grooves and clamped. A light smear of compatible grease at the inner lip can help seal and reduce chafe — avoid petroleum products if the boot is EPDM.

• Common signs it’s time: splits, accordion folds going shiny or hard, tyre toe wear, steering feel going notchy, oily residue inside the boot.
• Good practice after replacement: book a wheel alignment, as toe can shift even with careful marking.
• Care tips: avoid jacking by or grabbing the tie rods, rinse road salt or beach sand from underbody areas, and check boots after off-road trips.

Popular questions about 2008 Mitsubishi Outlander rack-boots

How long do rack-boots last on a 2008 Outlander?
With normal city and highway use, quality rack-boots can last many years. In hotter climates, on gravel, or with frequent lock-to-lock parking manoeuvres, rubber ages faster. Inspect at each service and plan replacement at the first sign of cracking rather than waiting for a tear.

Can they drive with a torn rack-boot?
They can, but it’s risky. A torn boot lets grit into the inner tie rod and rack, which can quickly lead to play, noise and seal damage. If fluid is collecting in the boot, it may point to a leaking rack that needs attention soon to avoid bigger bills.

Do they need a wheel alignment after replacing rack-boots?
Yes, a wheel alignment is recommended. Even when counting threads and marking positions, the toe setting can shift slightly when the outer tie-rod end is removed and refitted.
