Parts for your 1987 Suzuki Jimny-Cv joint

1987 Suzuki Jimny CV joint — what’s fitted and how to look after it

Yes, a CV joint is relevant to the 1987 Suzuki Jimny. Technical references including the Suzuki SJ413/Samurai Factory Service Manual (front axle and steering knuckle sections), the Haynes Suzuki SJ410 & SJ413 manual, and Suzuki parts catalogues identify a Birfield-type constant-velocity joint at each front axle end inside the swivel hubs. That means the 1987 Jimny (SJ413/Samurai era) runs CV joints up front, the rear live axle does not.

The Birfield CV joint lets the Jimny send drive to the front wheels while they steer and cycle over bumps, keeping power delivery smooth at big steering angles. On-road it’s about vibration-free motoring, off-road it’s about getting torque down when the wheels are turned and loaded on rough tracks. Unlike many IFS 4x4s, there’s no external rubber “CV boot” here—these joints live inside the swivel hub and bathe in grease behind the knuckle wiper seals.

As part of routine servicing, owners should keep an eye on a few tell-tales. Grease flung around the back of the knuckle or onto the inside of the rim points to tired knuckle wiper seals. Clicking or knocking on full lock in 4WD under throttle, shudder under load, or glittery metal in the knuckle grease are classic early warnings that a Birfield is wearing. Water crossings and beach work accelerate wear, so shorter service intervals make sense for Kiwi and Aussie conditions.

Good practice is to inspect every 10,000 km and plan a swivel hub/knuckle service at sensible intervals or when seals start weeping. That job typically includes: strip the free-wheeling hub and wheel bearings, pull the axle, clean the Birfield, check for pitting or brinelling, repack with quality moly CV grease, and renew the inner axle oil seal plus the felt/rubber knuckle wipers. While it’s open, check kingpin bearings and wheel bearing preload—cheap insurance.

Replacement is straightforward for a competent DIYer with stands and the right sockets, but a press and a torque wrench help. If the splines are clean and the bell race isn’t pitted, a clean-and-repack can buy plenty more kilometres. If there’s visible damage or persistent clicking, fit new Birfields or quality chromoly upgrades and you’re back to reliable low-range fun.

• Watch for grease leaks at the knuckle wipers
• Use high-moly CV grease and keep contaminants out
• Service sooner after deep water or sand work

Popular questions about 1987 Suzuki Jimny CV joints

Does a 1987 Jimny have CV boots?
Not in the usual IFS sense. The Birfield CV sits inside the swivel hub and is sealed by felt/rubber knuckle wipers. If those wipers leak, you’ll see grease around the back of the knuckle or on the wheel. Treat leaking wipers as a prompt to open, clean, and repack the joint.

How can someone tell a Birfield is failing?
Common signs are clicking on full lock in 4WD under throttle, vibration under load, binding while turning, or metallic flakes in the knuckle grease. Excess play felt at the drive flange with the hub unlocked can also hint at internal wear. If in doubt, pull it down and inspect the races and cage.

What grease and service interval suits Aussie/NZ use?
A quality molybdenum disulphide CV grease is the go. Inspect every service (around 10,000 km), do a full swivel hub clean, repack and seal refresh at sensible intervals, and sooner if there’s mud, water, or sand use. After river crossings, don’t delay—contaminants kill Birfields fast.
