A: If CV joints show wear, consider rebuilt CV axles or split boots from auto parts stores to save time. ABS-equipped models need ABS sensor rings inspection for any damage. To overhaul, remove the CV axle, then the inner CV joint and boot. Mark the tripod-outer race relationship before disassembling, cleaning, and inspecting the tripod assembly for abnormal wear. Replace if necessary. During reassembly, slide on the clamps and boot, install new stop-ring and bearing retainer clip, repack with CV joint grease, equalize boot pressure, and tighten boot clamps. Reinstall the CV axle.
