Finally, inspect the drive axle boots for tears, cracks, and loose clamps, as they are important in preventing dirt, water, and foreign material from damaging the constant velocity (CV) joints. If there is evidence of cracks or leaking lubricant, the boots must be replaced.

Inspection includes cleaning the components with solvent to remove all grease residues and scrutinizing the cage and races for wear, damage, pitting, score marks, or cracks. Shiny, polished spots are generally considered normal. During reassembly, insert the inner race into the cage, ensuring matchmarks align, and press the balls into the cage windows. Protect the axleshaft splines, slide the small boot clamp and boot onto the axleshaft, and position the inner race and cage assembly on the axleshaft. Insert the snap-ring, fill the boot with CV joint grease, manually pack grease into the inner race and cage assembly, and complete the assembly process.
