Axle shafts in vehicles employ two types of CV joint. The outer CV joint is a traditional design that delivers power from the axle shaft to the wheel hub, allowing for suspension and steering motion. The inner joint uses a triple roller bearing system to minimize vibration and noise, allowing the axle shaft to adjust for suspension travel. To replace a CV joint or boot, the axle shaft must be removed. The process starts by prying off the center cap on the road wheel and loosening the axle shaft staked collar nut at the wheel hub. Next, raise the vehicle and remove the front wheel, splash shield, front end reinforcement, ABS wheel speed sensor, and front brake caliper (without detaching the brake fluid line). Then, detach the tie rod end, tension strut, bushing, and control arm from the steering knuckle. Remove the axle shaft collared nut and disengage the shaft from the steering knuckle. Using a special tool, force the axle shaft inner CV joint shaft out of the front differential, catching any dripping oil. Replace the differential or bearing pedestal flange seal when the axle shaft is out and replace CV joint boots if necessary. Always replace the inner CV joint locking circlip. During installation, coat the sealing lip of the flange seal with transmission fluid and ensure the inner CV joint shaft locks in place. Use a new collar nut and fasten securely. Check and refill the front differential oil if needed.For front differential flange seal replacement, remove the axle shaft and steering knuckle together. Remove the old seal and install a new one, ensuring the seal's lip is lubricated with transmission fluid before reinserting the axle shaft. When replacing the outer CV boot, obtain a repair kit. Remove the axle shaft, release clamps, and remove the boot. After inspecting the CV joint, place new clamps and the boot over the axle shaft, secure with fresh lubricant, and reinstall.For inner CV boot replacement, again use a repair kit. After removing the axle shaft, detach the inner CV joint housing, remove the triple roller bearing, and replace the boot. Clean off old lubricant, install the new boot, replace the triple roller bearing, pack with grease, and reassemble. Always top off the differential fluid after any work.
