The CV boots are very important because they prevent dirt, water, and foreign material from entering and damaging the constant velocity (CV) joints. Oil and grease can cause the boot material to deteriorate prematurely, so it's a good idea to wash the boots with soap and water. Because it constantly pivots back and forth following the steering action of the front hub, the outer CV boot wears out sooner and should be inspected regularly. Inspect the boots for tears and cracks as well as loose clamps. Inspect the inner and outer CV boots for loose clamps, cracks, or signs of leaking lubricant. All-wheel drive models have CV boots at the rear too. If there is any evidence of cracks or leaking lubricant, they must be replaced.

If necessary, use a hammer and brass punch to drive the tripod joint from the driveaxle. Slide the boot off the axleshaft for inspection.

The purpose of driveaxle boots is to prevent dirt, water, and foreign material from entering and damaging the constant velocity (CV) joints.

Use a center punch to mark the relationship between the tripod and the axleshaft to ensure proper installation.

Slide the boot into place, position the CV joint mid-way through its travel, equalize boot pressure, and tighten the boot clamps.

If there is evidence of cracks or leaking lubricant in the driveaxle boots, they must be replaced.
