Lubrication of U-Joints & Driveshafts on Your UAZ
A well-lubricated drivetrain is essential to keep your UAZ in top condition. The U-joints and splines on the driveshafts take a beating during off-road driving. Regular greasing prevents wear, slack, rust, and vibration issues.
Why Grease?
U-joints contain needle bearings that rely on proper lubrication to avoid metal-on-metal contact. Without grease, they wear rapidly, leading to play, noises, or even seized joints.
For vehicles driven through water, mud, or sand, greasing is even more critical. Fresh grease pushes out dirt and moisture, keeping the bearings protected.
Grease Point Overview – UAZ 4x4 (Bukhanka, 469, Hunter)
| # | Location | Component |
|---|---|---|
| 1–3 | Door hinges & stops | Prevents squeaks and wear |
| 4–7 | Steering rods + ball joints | Maintains steering precision |
| 8–10 | Front axle U-joints | Prevents play and vibrations |
| 11–13 | Rear axle U-joints | Protects against overloading and wear |
| 14 | Center bearing (if fitted) | May include grease nipple |
| 15 | Driveshaft slip yoke/spline | Prevents sticking or knocking |
| 16–18 | Handbrake levers | Inside cabin and underbody |
| 19–21 | Gear shift linkages | Improves shifting feel |
| 22 | Clutch linkage rod | Between pedal and fork lever |
| 23–25 | Pedal linkages | Brake, clutch, accelerator |
| 26 | Steering box and joints | Affects steering response |
| 27 | Transfer case selector linkage | Often neglected, prone to stiffness |
Total: 20–25 grease fittings on a typical UAZ depending on version and transfer linkage.
How to Grease Properly
- Use a quality grease gun with EP2 lithium- or calcium-based bearing grease
- Needle adapters help with tight spots and flush-mounted zerks
- Grease until fresh grease oozes out of seals or joints
- Clean the fittings with a cloth before attaching the gun (dirt + grease = lapping paste!)
- Move the vehicle slightly to access hidden nipples if needed
Recommended Greasing Intervals
- Normal use: every 10,000 km or once a year
- Off-road, wet, or dusty conditions: every 3,000–5,000 km or after each major trip
