Parts for your 1998 Mitsubishi Pajero-Coil springs

1998 Mitsubishi Pajero coil springs — fitment, purpose and service advice

Coil springs are relevant to the 1998 Mitsubishi Pajero (NL series). Technical sources confirm the model uses a coil‑sprung live rear axle with trailing arms and a Panhard rod, while the front runs double‑wishbone suspension with torsion bars. This layout is documented in the Mitsubishi Pajero NL (1997–1999) workshop manual, chassis/suspension sections, the Gregory’s 518 Pajero NG–NL manual (1991–1999), the Haynes Mitsubishi Pajero/Montero 1983–1999 manual, and AU/NZ parts catalogues (e.g., Mitsubishi ASA/CAPS and major spring/shock catalogues) that list rear coil springs for NL Pajero variants.

On the 1998 Pajero, the rear coil springs carry the vehicle’s weight, set ride height and keep the back end settled over corrugations, towing loads and off‑road ruts. Paired with the shocks, they let the axle move while keeping the tyres in contact with the road or track. That’s the difference between a planted, predictable wagon and a wallowy one that chews out tyres and feels skittish on gravel.

Because they’re just steel, coil springs don’t “wear out” like a rubber bush, but they do sag, lose rate over big kilometres, and can crack from corrosion or overload. Owners who tour, tow a boat or camper, or carry drawers and a fridge will often notice a tail‑low stance, more body roll or a thump over bumps — all signs it’s time to refresh the coils.

Good practice is to inspect the rear coils at each service interval: look for chipped paint, rust pitting, broken pigtails, and shiny “coil bind” marks. Measure ride height side‑to‑side, uneven numbers suggest a weak spring. If replacement’s on the cards, swap coils in pairs, choose a spring rate that matches typical load (standard, constant‑load, or heavy‑duty), and fit new insulators/isolators. It’s smart to assess the shocks at the same time, as tired dampers can make good coils feel ordinary.

A quality spring compressor and safe support of the axle are critical. Many Pajero specialists can do the job quickly, set rear ride height properly and check related items — bump stops, Panhard rod bushes and trailing arm bushes. After fitting, confirm headlight aim, brake bias operation and that the vehicle sits level. Keeping the springs clean and salt‑free, and avoiding chronic overloading, helps them last the distance and keeps the Pajero feeling tight on a long Kiwi or Aussie road trip.

• Replace if: rear sits low, cracks/corrosion are visible, or handling becomes floaty.
• Reassess springs when adding accessories (towbar, drawers, long‑range tank).
• Expect long service life, but 200,000–300,000 km vehicles often benefit from fresh coils.

Popular questions about 1998 Mitsubishi Pajero coil springs

Does a 1998 Pajero have rear coil springs or leaf springs?
It uses rear coil springs on a live axle with trailing arms and a Panhard rod. The front end is independent with torsion bars, not front coils. This combo delivers a good blend of comfort and durability for touring and light‑to‑medium off‑road work.

When should the rear coil springs be replaced?
There’s no fixed interval, but many high‑kilometre NLs benefit from new coils, especially if they tow or carry constant load. Replace when the rear sags, the ride gets bouncy or uneven, or any coil damage is found during inspection. Always replace in pairs.

Will heavy‑duty coils help with towing?
Yes — matched heavy‑duty or constant‑load coils better support ball weight and gear, keeping the Pajero level and stable. Pair them with suitable shocks and stay within legal ride‑height and GVM limits. Air‑assist bags inside standard‑rate coils can also help fine‑tune height under varying loads.
