Parts for your 1986 Suzuki Jimny-Control arms

1986 Suzuki Jimny: Are control arms used, and what to check instead

For the 1986 Suzuki Jimny (also known locally as the Sierra, and overseas as the SJ410/SJ413/Samurai), control arms aren’t part of the factory suspension. Technical sources including the Suzuki SJ413/Samurai Factory Service Manual (1986, Suspension section), Gregory’s Service and Repair Manual No. 505: Suzuki Sierra 1.0 & 1.3 (1982–1998), and the Haynes Suzuki SJ410 & SJ413 manual all describe solid front and rear live axles located by semi‑elliptic leaf springs and shackles. No upper, lower, radius, or trailing control arms are specified for this model year. Suzuki’s published Jimny model history also notes the shift to coil-sprung, multi-link control-arm layouts didn’t arrive until the later coil-sprung Jimny generation in the late 1990s.

Why no control arms? On a leaf-sprung solid axle, the leaf springs themselves handle axle location fore–aft and, with the spring clamps and chassis mounts, help with lateral control. That means separate control arms (the bits you’d see on coil-sprung or double-wishbone setups) simply aren’t required on the 1986 truck.

If someone’s chasing “1986 Suzuki Jimny control-arms” today, they’re usually dealing with ride quality, wandering, clunks, or uneven tyre wear that’s actually tied to the leaf-spring hardware. On a stock 1986 Jimny/Sierra, it’s smart servicing to focus on:

• Leaf spring eye and shackle bushes (rubber or polyurethane), shackle pins, and hanger brackets
• U-bolts and spring plates (check torque and corrosion)
• Spring packs for cracked leaves, sag, or broken centre bolts
• Shock absorbers and bump stops
• Steering gear and damper, and front axle kingpin bearings for wander or shimmy

Typical signs it’s time for attention include steering wander, a harsh or bouncy ride, clunks over corrugations, rear-axle tramp under throttle, and uneven tyre wear. Fresh bushes and correctly torqued U-bolts can transform how these little rigs drive on Kiwi and Aussie roads and tracks. If control arms are a must-have, there are specialist coil-spring conversion kits that add radius/leading arms and a panhard rod—but that’s a full engineering job and usually needs certification for road use in Australia and New Zealand.

• Does a 1986 Suzuki Jimny have control arms?
  No. The 1986 model uses leaf-sprung solid axles, so there are no factory control arms. This is outlined in the Suzuki SJ413/Samurai Factory Service Manual (1986) and mainstream repair manuals for the SJ/Sierra.
• What should be serviced instead of control arms on a 1986 Jimny?
  Focus on leaf spring eye and shackle bushes, shackle pins, U-bolts, spring packs, shocks, and the steering damper. These are the usual culprits behind play, noise, and poor handling.
• Can control arms be fitted to a 1986 Jimny?
  Only with a coil-spring conversion that adds arms and a panhard rod. It’s a major modification and will typically require engineering approval/compliance in AU/NZ.
