Parts for your 1999 Mitsubishi Pajero-Coil springs

1999 Mitsubishi Pajero coil springs — what they do and when to replace them

Based on the Mitsubishi Pajero NL (1997–1999) Workshop Manual and Gregory’s Service & Repair Manual (1991–1999), the 1999 Pajero uses rear coil springs with a five-link live axle, while the front runs double wishbones with torsion bars. Monroe and KYB suspension catalogues back this layout. In some markets a late-1999 third‑gen (NM) Pajero arrived with independent suspension and coil springs at both ends, but for most Australian and New Zealand 1999 models, rear coils are the go. So yes—coil springs are very much relevant on a 1999 Pajero.

On this Pajero, the rear coil springs carry the vehicle’s weight, set ride height, and keep things level under load. They work with the shocks to maintain tyre contact and comfort, whether it’s corrugations in the Outback or a wet gravel road in the Waikato. Healthy coils help stability when towing or with gear in the back, and they preserve ground clearance and approach/departure angles off‑road.

As part of regular servicing, it’s smart to inspect the rear coils every 20,000–30,000 km for rust pitting, cracked paint, broken ends, and rubber isolators that have perished. Watch for a tail‑down stance, a lean to one side, or a harsher, bouncy feel—classic signs of sagging or a cracked spring. Uneven rear ride height, bottoming out over speed humps, or new scrape marks on the bump stops are other tell‑tales.

Replacement tips for a 1999 Pajero:

• Replace coils in axle pairs to keep ride height and handling even.
• Choose springs to match use: OE‑equivalent for daily duty, or quality heavy‑duty/progressive‑rate coils for towing, touring, or drawer systems.
• Match spring rate with compatible shocks, a heavier spring on tired shocks won’t ride well.
• Renew rubber isolators/seats and check bump stops while you’re in there.
• Tighten suspension arm bolts at normal ride height to avoid bush preload.
• Get a wheel alignment after any suspension change.

If chasing a lift, stick to compliant heights and components accepted in Australia and New Zealand. A spring upgrade won’t increase legal GVM on its own—certification may be required.

Look after the Pajero’s rear coils and it’ll sit level, ride nicely, and keep traction where it counts.

Popular questions about 1999 Mitsubishi Pajero coil springs

Do all 1999 Pajeros have coil springs at the front?
Most 1999 AU/NZ models (NL) run front torsion bars and rear coil springs. Some late‑1999 third‑gen (NM) Pajeros in other markets switched to coils front and rear. Check the VIN/build plate and front lower control arm setup to confirm which you’ve got.

How long do Pajero rear coil springs last?
There’s no fixed expiry, but many last well past 200,000 km if not overloaded or corroded. Replace if ride height sags, a coil is cracked, it leans side‑to‑side, or it bottoms out. Frequent towing or corrugations can bring replacement forward.

Will heavy‑duty coils fix a saggy rear when towing?
They help maintain ride height and control with ball weight or cargo. For big loads, consider matched shocks and possibly load‑assist options. Note that heavier coils don’t increase legal GVM, follow local certification rules if uprating capacity.
