Parts for your 1999 Suzuki Jimny-Wheel studs nuts

1999 Suzuki Jimny wheel studs and nuts

Based on Suzuki’s workshop literature for the JB33/JB43 series and the Suzuki Electronic Parts Catalogue for the 1999 model year, the 1999 Suzuki Jimny uses wheel studs with separate wheel nuts (not wheel bolts). The owner’s manual and service data for this generation also specify a wheel nut tightening torque in the typical range of 100 N·m, confirming the stud-and-nut arrangement is standard fitment.

On a 1999 Jimny, the wheel studs and nuts do the heavy lifting of clamping the wheel securely to the hub. Five studs per corner, a 5×139.7 mm PCD, and M12 × 1.25-thread conical-seat nuts are commonly specified for OEM wheels. That clamping force is what keeps the wheel true through corrugations, beach runs, and city commuting alike. It also makes wheel changes straightforward on trips, which is exactly what a light 4x4 like a Jimny is built for.

As part of regular servicing or any tyre rotation, it pays to give the studs and nuts a once-over. Clean the mating faces of the hub and wheel, run the nuts on by hand to ensure the threads feel smooth, and tighten in a star pattern with a torque wrench to the factory spec (typically around 100 N·m—check the Jimny’s handbook for your market’s figure). Avoid lubricating threads or using anti-seize on the seats unless the service manual explicitly calls for it, as it can distort clamp load.

Signs it’s time to replace include: damaged or stretched threads, a nut that won’t hold torque, visible rust pitting at the seat, or a bent/broken stud. If replacing, press the old stud out from the rear of the hub and draw the new one in square using a suitable spacer and nut, or a press. On the front, this may involve removing the brake calliper and disc, on the rear, the drum or disc needs to come off. Replace any suspect nuts at the same time, and if multiple studs show damage, consider renewing the set on that hub.

After any wheel-off work, re‑torque the nuts after 50–100 km of driving. For off‑roaders who do water crossings or beach work, a periodic inspection for corrosion is smart preventative maintenance.

• Typical fitment: 5×139.7 PCD, M12 × 1.25 thread, 60° taper-seat nuts
• Tightening: star pattern with a calibrated torque wrench
• Service tip: re‑torque after 50–100 km and never rely on a rattle gun for final tightening

What is the correct wheel nut torque for a 1999 Suzuki Jimny?
Factory literature for this generation Jimny lists a wheel nut torque around 100 N·m. Always check the specific figure in the owner’s handbook or service manual for your market. Use a torque wrench and tighten in a star pattern, then re‑torque after 50–100 km whenever the wheels have been off.

What size are the wheel studs and nuts on a 1999 Jimny?
The OEM setup is commonly M12 × 1.25 studs with 60° taper-seat nuts on a 5×139.7 mm bolt pattern. Many factory nuts take a 19 mm socket, but aftermarket nuts can vary. Match the thread pitch and seat style to your wheels to ensure proper clamping.

How do you replace a broken wheel stud on a Jimny?
Safely support the vehicle, remove the wheel, brake calliper and rotor (or drum) as needed, then press or drive the damaged stud out from the rear of the hub. Draw the new stud in square using a suitable spacer and a sacrificial nut, or a press. Reassemble, torque the wheel nuts to spec, and re‑torque after 50–100 km. If one stud failed, inspect the rest for damage or stretch.
