Parts for your 2002 Toyota Land cruiser-Coil springs

2002 Toyota Land Cruiser coil springs — what they do and how to look after them

Coil springs are absolutely relevant on a 2002 Toyota Land Cruiser. Technical references including Toyota’s New Car Features (100/105 Series) and the Toyota Factory Repair Manual for the 100/105 Series document that most 100 Series models use independent front suspension with torsion bars and a live rear axle with coil springs, while the 105 Series runs coil springs on both front and rear solid axles. Australian-market VX and Sahara variants with Adaptive Height Control still retain coil springs alongside the hydraulic system. Gregory’s/Haynes service manuals for 1998–2007 100/105 Series back this up, listing inspection and replacement procedures for the rear (100) and both ends (105) coil springs.

On this Land Cruiser, the coil springs carry vehicle weight, keep ride height where it should be, and team up with the shocks to control body movement over corrugations and rough tracks. A healthy set delivers stable towing, predictable steering, and decent comfort on long Kiwi and Aussie road trips.

Owners should keep an eye out for sagging (tail-down stance when loaded), uneven ride height side to side, bottoming out over speed bumps, clunks, or a choppy/floaty feel. Surface rust, cracked paint, or broken pigtails are all red flags. As part of regular servicing, a quick visual every 20,000 km or 12 months is smart, touring or off-road use may justify more frequent checks.

• Replace coil springs in axle pairs to keep the vehicle level and predictable.
• Choose rate/height to match real-world loads: OE-equivalent for stock touring, constant-load or heavy-duty coils for barwork, drawers, or towing. Avoid mixing heights or brands on the same axle.
• Always support the vehicle safely and use a proper spring compressor where required. Re-torque suspension hardware at normal ride height.
• After any spring change, book a wheel alignment and check shock absorbers, bump stops, upper/lower control arm bushes, and the rear panhard rod bushes.
• For AHC models, inspect the springs and also verify hydraulic height control operation and fluid condition.

There’s no fixed replacement interval, but many see noticeable sag by 150,000–250,000 km depending on load and terrain. If the Cruiser works hard—towing a van across the Nullarbor or hauling gear into the High Country—upgrading spring rate and pairing with quality shocks can restore stance and reduce driver fatigue.

Popular questions about 2002 Toyota Land Cruiser coil springs

Do all 2002 Land Cruisers have coil springs front and rear?
Not exactly. The 105 Series uses coils front and rear. Most 100 Series have torsion bars up front and coil springs at the rear. Both setups still rely on coils somewhere in the suspension, so coil-spring servicing remains relevant. Some higher-spec models with Adaptive Height Control still run coil springs in conjunction with the hydraulic system.

How can someone tell if their Land Cruiser’s coil springs are due for replacement?
Look for a sagging rear, a nose-up or tail-down stance when loaded, uneven ride height, scraping or bottoming on speed humps, and a nervous, bouncy feel. Visual signs include cracked paint, corrosion, or a distorted coil. If fitting accessories or towing frequently, upgrading spring rate can fix stance and stability at the same time.

Is a wheel alignment needed after changing coil springs?
Yes. Ride height affects geometry. After spring changes—front or rear—it’s best practice to get a full alignment and to recheck fastener torque after a short shakedown drive. This keeps tyre wear in check and handling consistent.
