Parts for your 1988 Mitsubishi Pajero-Rack boots

1988 Mitsubishi Pajero rack-boots — are they used?

Short answer: rack-boots aren’t relevant on a 1988 Mitsubishi Pajero. Technical documentation shows the ’88 Pajero (first‑gen L040 series) uses a recirculating ball steering box rather than a rack‑and‑pinion unit, so there’s no steering “rack” to cover with bellows/boots. This is detailed in Mitsubishi’s Factory Service Manual (1982–1991, Group 37: Steering), the Mitsubishi ASA electronic parts catalogue for L040 chassis, and common aftermarket manuals (e.g., Gregory’s/Haynes for 1983–1991 Pajero). Those sources list a steering gearbox with a pitman arm, relay/centre rod, idler arm and tie‑rod assemblies—no rack, no rack‑boots.

Why it’s not used: on a body‑on‑frame 4x4 like the Pajero, the recirculating ball setup is chosen for durability, steering leverage and clearance under the front end. It copes well with off‑road loads and tyre upsizes, and packaging around the diff and crossmembers is easier without a rack. Because there’s no rack‑and‑pinion, there are no rack boots to split, clamp or replace.

What owners should look at instead are the boots and bushings that actually live on the Pajero’s front end. If the goal was to book in “rack‑boots” for a service, swap focus to these items instead:

• Tie‑rod end dust boots and relay/centre rod joints
• Idler arm bush/bearing and pitman arm seals
• Upper and lower ball joint boots
• Front CV boots (IFS models) and steering box sector shaft seal

Good servicing practice in AU/NZ: check these boots at every service or around each 10,000–15,000 km, and before WOF/reg inspections. Torn or perished boots let water and grit in, which quickly kills the joint and can make steering vague or cause a shimmy. Use quality OEM‑equivalent boots, clean the joint seats, and clamp properly. If any steering joint is replaced, get a wheel alignment straight after. Where grease nipples are fitted, a light pump of the correct grease goes a long way. If there’s free play at the wheel, check the idler arm and centre link before blaming tyres or balance.

Bottom line for this model year: a workshop invoice shouldn’t list “rack‑boots” on a 1988 Pajero—if it does, query it. Ask for inspection or replacement of the actual steering and suspension boots listed above for a safe, tidy result.

FAQs

Does a 1988 Mitsubishi Pajero have steering rack boots?
No. The ’88 Pajero runs a recirculating ball steering box, not a rack‑and‑pinion. There’s no steering rack, so there are no rack boots to replace. The manuals and parts catalogues for the L040 series confirm this layout.

What should be checked instead of rack‑boots on a 1988 Pajero?
Focus on tie‑rod end boots, the relay/centre rod joints, idler arm bush/bearing, ball joint boots, and the CV boots. Any tears, grease sling or play means it’s time for parts and an alignment afterwards.

Can universal rack boots be fitted to make it work?
They won’t fit or serve any purpose on this steering system. Spend the coin on the correct steering joint boots and idler arm kit for the Pajero instead—far better outcome and keeps WOF/reg inspectors happy.
