A CV joint boot seals grease inside the constant-velocity joint and keeps dirt and water out; once it splits, grease escapes and contamination sets in, quickly wearing down the joint until it fails.
Inner and Outer Drive Shaft Boot Types
A drive shaft boot is not a one-size-fits-all part: the inner boot near the differential and the outer boot near the wheel hub differ in diameter, flexibility, and clamp size, so rubber parts must be matched to the exact joint location, vehicle make, model, and production year.
Signs of a Torn Boot and When to Replace It
A clicking noise on turns, grease flung around the wheel well, or visible cracks and splits in the rubber all signal that the boot needs replacing immediately — delaying the fix risks a far more expensive joint replacement.
