Parts for your 1999 Nissan Navara-Cv boots

1999 Nissan Navara CV Boots — What they are and when to sort them

Technical references confirm that CV boots are applicable to the 1999 Nissan Navara D22 when it’s a 4WD: the Nissan Navara D22 Factory Service Manual (Front Axle/Front Suspension sections) shows front drive shafts with inner and outer constant velocity joints protected by rubber boots, and the Nissan FAST electronic parts catalogue lists CV boot components for D22 4x4 variants. By contrast, the 2WD D22 front end has no front drive shafts, so there are no front CV boots to service. General repair guides (e.g., Gregory’s/Haynes for D22/Frontier) also detail CV joint and boot service only for the 4WD models.

For 4WD owners, the CV boots on a 1999 Navara do a deceptively simple but vital job: they keep thick moly grease in the CV joints and keep water, mud, and grit out. That protection is what stops clicking joints on lock, vibration under load, and ultimately expensive axle replacements. Off-road use, coastal sand, and big temperature swings in Aus and NZ are tough on rubber, so ageing and splits happen.

It pays to give the boots a look every service. A quick torch check for fine cracks, missing clamps, or a sling of grey grease on the inside of the wheel or control arm will catch issues early. If a boot is torn, replacing it promptly—before the joint runs dry or swallows grit—can save the CV. Use quality neoprene or TPE boots, fresh moly CV grease, and stainless clamps. Where a joint already clicks or has heavy play, a complete shaft assembly is often better value than just a boot.

Typical workshop time to replace a single boot is around an hour or two depending on side and tooling, but timelines stretch if the axle is seized in the hub or the bash plates and guards fight you. Torque specs and hub nut staking should follow the Nissan FSM. After deep mud or water crossings, a quick clean and re-check of the boots and clamps is smart. Lifted suspensions can alter CV angles and stress boots, so more frequent inspections make sense on kitted rigs.

• Check at each service or 10,000–15,000 km, sooner after off-road trips.
• Replace at the first sign of cracking, grease weep, or loose clamps.
• Consider full shaft replacement if there’s clicking on full lock or blueing/pitting inside the joint.

Note for 2WD D22 owners: there aren’t front CV boots to maintain. Focus instead on tie-rod and ball joint dust boots, and the rear prop shaft universal joints.

Popular questions about 1999 Nissan Navara CV boots

Does my 1999 Navara actually have CV boots?
Yes if it’s a 4WD (D22 IFS front end with drive shafts). If it’s a 2WD, there are no front CV boots. A quick glance behind the front wheels will tell the story: see a shaft running from the diff to the hub with rubber bellows at each end? That’s a CV with boots.

How often should CV boots be checked or replaced?
Have them checked at every service or roughly every 10,000–15,000 km, and straight after heavy off-road or water work. Replace boots as soon as cracks or grease leaks appear. There’s no fixed kilometre replacement interval—condition and use case rule the decision.

Can someone keep driving with a torn CV boot?
It’s not recommended. Grease will fling out and water and grit will get in, which turns a simple boot job into a noisy, worn-out CV joint. If a tear’s just happened, a prompt boot replacement can save the joint, if there’s clicking on lock, the joint is likely already damaged.
