Parts for your 1999 Mitsubishi Lancer-Rack boots

1999 Mitsubishi Lancer rack boots: what they do, why they’re fitted, and when to replace them

Yes, the 1999 Mitsubishi Lancer uses rack boots. Technical references including the Mitsubishi factory workshop manual for CJ/CK/CE Lancer models (Steering: Rack and Pinion section), the Mitsubishi ASA/CAPS electronic parts catalogue (listing steering gear bellows/boots for these chassis), and common aftermarket fitment catalogues for the 1996–2003 Lancer all show rubber bellows fitted at each end of the steering rack to cover the inner tie rods. That means rack boots are relevant, standard equipment on the 1999 Lancer, and part of its regular steering service items.

On a ’99 Lancer, rack boots (also called steering rack bellows) are the flexible rubber sleeves that seal the ends of the rack-and-pinion housing. Their job is simple but crucial: keep grit, water, and road splash away from the polished rack bar and inner tie rod joints, while trapping a bit of grease inside so the joint can move freely. When the boots split, grime and moisture get in, the inner tie rod wears fast, and the rack can start to rust or bind. If the boot is torn and there’s oily residue inside, that can also hint at a leaking power-steering rack seal.

As part of routine servicing, it’s smart to eyeball both rack boots for cracks, splits, loose clamps, and signs of rubbing. On older CE/CK Lancers the rubber can harden with heat and age, so even small surface cracks are a cue to plan replacement. Boots are inexpensive compared to a steering rack, and replacing them early helps avoid a bigger bill down the track.

• Common signs it’s time: visible tears, grease flung around the subframe, uneven steering feel, or a WOF/RWC note about steering dust covers.
• Good practice when replacing: fit quality boots with new clamps, clean the rack bar, regrease the inner joint, and check inner and outer tie rod play.
• After any steering work: set toe and get a proper wheel alignment to protect your tyres and steering feel.

DIY-savvy owners can tackle rack boots with stands, a tie-rod tool, and patience, but seized locknuts are common on Lancers of this age, so a workshop may save time. Whether it’s a daily runabout in Aussie heat or a Kiwi city car clocking up the kilometres, fresh rack boots help the Lancer steer smoothly and keep it onside for WOF or RWC checks.

Popular questions about 1999 Mitsubishi Lancer rack boots

How often should rack boots be replaced on a 1999 Lancer?

There’s no fixed interval, they’re replaced on condition. Have them inspected at every service. If the rubber shows cracking, if a clamp is loose, or if there’s any tearing, replace them straight away. Many last years, but age, heat, and road grime can shorten their life.

Can torn rack boots cause a WOF/RWC fail?

Yes. In both NZ and Australia, damaged steering dust covers (rack boots) can lead to WOF or RWC failure. They’re considered protective components for a safety-critical system. A quick boot replacement and alignment usually sorts it.

Do both sides need replacing if only one boot is torn?

It’s common to replace boots in pairs, especially on older Lancers. If one has perished, the other is often close behind. Doing both sides at once saves repeat labour and keeps the steering protection consistent.
