Parts for your 1987 Suzuki Jimny-Universal joints

1987 Suzuki Jimny universal-joints (U-joints)

Universal-joints are absolutely relevant to a 1987 Suzuki Jimny (SJ413/Samurai). Technical sources that confirm this include the Suzuki SJ413/Samurai Factory Service Manual (Driveline/Propeller Shaft sections covering universal joint inspection and replacement), the Suzuki Electronic Parts Catalogue listing a “Universal Joint, Propeller Shaft” for SJ410/SJ413 models, and aftermarket workshop texts such as the Haynes Repair Manual for Suzuki Samurai/SJ410/SJ413 (driveshaft and U-joint service procedures). These documents describe the front and rear propeller shafts fitted with cardan-type U-joints and detail service steps and specs.

On the 1987 Jimny, U-joints sit at each end of the front and rear prop shafts, letting the shafts transmit torque while the suspension articulates. Without them, the solid axles would bind as the vehicle moves over bumps and through angles. They’re small, but they cop a hard life—especially on lifted rigs or those that see plenty of corrugations, mud, and water crossings.

Servicing is straightforward. Many Jimnys of this era run greasable U-joints, if yours has grease nipples, give them a quality lithium-moly or EP grease every oil change or 10,000 km, and after any deep-water or muddy trips. If the joints are sealed, inspect them regularly and replace at the first sign of wear. Symptoms to watch for include:

• A light chirp or squeak at low speed that comes and goes with road speed.
• A clunk when taking off or shifting from drive to coast.
• Vibration through the floor at certain speeds, often worse under load.
• Red-brown dust around bearing caps, or any play when twisting the shaft by hand.

Replacement is a DIY job for a careful home mechanic with circlip pliers, a vice or press, and a torque wrench. Mark the flanges and yoke positions before removal so the shaft goes back in phase and stays balanced. Press the old caps out gently, clean the yokes, seat the new caps square, and make sure the snap rings sit flush in their grooves. Refit the shaft, aligning your marks, and tighten flange fasteners to the factory torque. Aftermarket heavy-duty, greasable joints are popular for off-road use, sticking with known brands helps longevity.

Worth noting: the front axle outer joints on a Jimny are constant-velocity (Birfield) joints, not U-joints—different parts with different service procedures. For the prop shafts though, a well-greased, correctly phased U-joint keeps the little Suzuki smooth, quiet, and ready for the next track.

Popular questions about 1987 Suzuki Jimny universal-joints

Do 1987 Jimnys use U-joints or CVs?
They use cardan U-joints on the front and rear propeller shafts. At the front steering knuckles, the Jimny uses CV (Birfield) joints. So, U-joints handle driveline angles in the props, while CVs handle steering angles at the hubs.

How often should the U-joints be serviced?
If the joints are greasable, service them every 10,000 km or at each engine oil change, and immediately after water or mud work. Sealed joints don’t get greased, so inspect them routinely for noise, vibration, or play and replace when wear shows up.

What are the classic signs a U-joint is failing?
A chirp that speeds up with road speed, a take-off clunk, and a mid-speed vibration are the big three. Rusty dust around the caps or any free play when twisting the shaft by hand are also red flags. Don’t leave it—replace the joint to protect the transfer case and diffs.
