If your CV joint is starting to go bad, this can result in a clicking sound coming from the joint. If you found a ruptured boot, there's a chance debris has gotten into your CV joint. To check it, pull and disassemble the joint. Look for galling, pitting, or signs of discoloration due to excessive heat. Our new CV joints will fit the first time with no issues - at a great price. This joint includes the gasket as shown. Another note - there's a rumor that these will also work on a Thing. They will physically fit, but the axle travel is different, so we suggest leaving these for the busses.
