While that flexibility helps isolate NVH from the cabin, the stock bushing is extremely prone to failure — especially in harsher climates and on higher-powered vehicles. When the bushing fails, excessive vibrations and clunking follow, placing the transmission and rear differential at serious risk of damage. Compounding the problem, the stock carrier is molded directly onto a non-serviceable center support bearing, meaning failure typically results in costly full driveshaft replacement rather than a simple bushing swap.\u003c\/div\u003e\n\u003cdiv class=\"tgk-p\"\u003eThis upgraded carrier keeps the driveshaft firmly centered at all times. Its polyurethane construction ensures the bushings will never wear out, maintaining consistent driveshaft alignment across all driving conditions.
