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.

Clean the old grease from the outer race and tripod bearing assembly and disassemble each section of the tripod assembly one at a time to clean the needle bearings with solvent.
