Starting at $53.95, AutoBuffy stocks 1 CV joint repair kits from Detroit Axle to fit the Ford Explorer. A CV joint repair kit restores the constant-velocity joint that transfers engine power to the wheels at a consistent speed through suspension travel. When the protective boot cracks and grease escapes, the joint wears rapidly, leading to vibration, noise, and eventual loss of drive.
The most important decision is whether you need a boot-only kit — used when the joint itself is still serviceable and only the boot has failed — or a complete joint-and-boot kit for a joint that has already run dry and worn. Position (inner vs. outer) and axle side (driver vs. passenger) also determine fitment, so confirm both before ordering.
| Option | Best for | What you get |
|---|---|---|
| Outer CV Boot Kit | Early catch — boot torn but joint is smooth and quiet with adequate grease | Replacement rubber or thermoplastic boot, clamps, fresh grease packet, and installation hardware |
| Inner CV Boot Kit | Boot failure at the transmission-side joint, which is often larger in diameter and uses a different boot profile | Oversized accordion-style boot sized for the inner tripod or double-offset joint, clamps, grease, and retaining clips |
| Complete Outer CV Joint & Boot Kit | Joint that has been clicking or running without grease long enough to show wear on the ball tracks or cage | Fully assembled or rebuildable outer joint, replacement boot, clamps, grease, and snap rings — no separate core needed |
| Full Axle Rebuild / CV Repair Kit | High-mileage axles with worn joints at both ends or damaged axle shaft splines, or when cost of separate kits approaches a full axle price | Inner and outer joints, both boots, all clamps and hardware, and grease — everything needed to restore one complete halfshaft |
Raise and support the vehicle safely, remove the wheel, and disconnect the axle from the hub and transmission according to the service procedure for the Ford Explorer. Disassemble the joint, clean all old grease from the joint internals, inspect races and balls for pitting or scoring, pack generously with the included grease, and seat the new boot securely before torquing all fasteners to the manufacturer's specification. Incorrect boot clamping or under-packing with grease are the two most common causes of premature failure after a DIY repair.
