If your JK Wrangler’s CV joint is damaged or worn out, it’s time for a Crown Automotive CV Joint Repair Kit. Driving on a worn out or damaged CV joint, whether due to a busted boot or prolonged driving on demanding terrain, can cause damage to other parts of the drive train. These joints are located at the transfer case end of the front drive shaft and axle end of the rear drive shaft. No need to replace the entire shaft, this kit will ensure your JK continues to drive safely both on the pavement and on challenging trails. In fact, the kit even comes with grease to keep the joint functioning perfectly on your toughest drives.
