I am about to replace my driveshaft carrier bearing for the second time with only 112,000 miles on my truck and I'm not happy about it. The dealer charges $95 for the part. Has any one else had problems with these? The symptom is a clunk when casually driving away from a stop. It's as if a load shifts. The rubber around the bearing gets soft, allowing the driveshaft yolk to bang against the steel mounting bracket. Maybe someone knows of an aftermarket polly version which is more durable.
