Parts for your 1990 Suzuki Jimny-Rack boots

1990 Suzuki Jimny (Sierra) — rack-boots, used or not?

Short answer: rack-boots aren’t used on the 1990 Suzuki Jimny (known as the Sierra in Australia and New Zealand). The steering on these models is a recirculating-ball steering box with a pitman arm, drag link and tie rods, not a rack-and-pinion setup that would use rack gaiters/boots.

This isn’t guesswork. Technical references including the Suzuki SJ410/SJ413/Samurai Factory Service Manual (Steering section), the Suzuki Electronic Parts Catalogue (EPC) for SJ70/SJ80-era Jimny/Sierra, and general guides such as the Haynes Suzuki SJ/Samurai manual all show a steering gear box arrangement with pitman arm, drag link and two tie rods. There’s no steering rack or rack gaiters listed or illustrated for 1990-production vehicles, which confirms there are no “rack-boots” to replace on this model.

Why no rack-boots? The 1990 Jimny runs a live front axle and was engineered for durability off-road. Recirculating-ball steering tolerates impacts and steering loads well, suits the packaging around a solid axle, and keeps the vulnerable moving bits tucked away from rocks and mud. Because there’s no rack-and-pinion, there’s no rack housing to protect and therefore no rack boots to split or leak.

If someone’s hunting for “steering boots” on a 1990 Jimny, they’re usually chasing one of these instead:

• Tie-rod end dust boots (at all four tie-rod/drag-link ends)
• Steering knuckle/swivel hub seals and wipers
• Steering box input/output shaft seals (not boots, but common leak points)
• Steering damper condition (again, not a boot, but worth a look)

As part of regular servicing, it’s smart to check for split or perished tie-rod end boots, free play in the drag link and tie rods, steering box oil seepage and correct adjustment, and the knuckle/swivel hub seals for weeping—especially if the vehicle sees a lot of beach work or muddy tracks. Keeping these bits in good nick preserves steering feel, helps with WOF/rego inspections, and prevents water or grit from chewing out joints and bearings.

Popular questions

Does a 1990 Suzuki Jimny/Sierra have rack-boots?
No. The 1990 model uses a steering box with pitman arm, drag link and tie rods, so there’s no steering rack and no rack gaiters to replace. Look to the tie-rod end boots and steering knuckle seals instead.

What “steering boots” should be checked on a 1990 Jimny?
Check the dust boots on all tie-rod and drag-link ends, plus the swivel hub/knuckle seals. These keep grease in and grit out, and once they split the joints wear quickly.

Can a rack-and-pinion be retrofitted to a 1990 Jimny?
It’s uncommon and not recommended for road use. The chassis, axle and geometry are designed around a steering box. Conversions require fabrication and engineering approval, and can compromise durability off-road.
