Keep the axle's inner CV joint sealed, greased, and protected with the Mevotech Duraflex CV Joint Boot (DX430). This front inner boot drops in as a direct-fit replacement for the 2002-2008 MINI Cooper and 2013-2018 Nissan Sentra (see the Buyer's Guide tab for the full engine-level fitment). Its job is simple but critical: it wraps the constant-velocity joint to hold lubricating grease in and keep road grit, water, and debris out, so the joint runs smoothly as the axle flexes and turns.
A torn or cracked boot lets grease sling out and contaminants in, which can lead to a clicking or knocking CV joint over time. If a failed boot is the cause, replacing it early helps protect the joint. Inspect the boot whenever it shows cracks, splits, or leaking grease.
