Last month, a shop fixed my leaky engine gaskets; As I was leaving they informed me my driveshaft u-joints were bad, I was backing out of the work-bay and my F-150 was going squeak-squeak-squeak; this noise reminded the tech to tell me about the driveshaft.The truck had been squeaking every time I went in reverse for the last year, never made the noise going forward.Got my u-joints replaced today and the mech showed me the old u-joints, the front u-joint had one seized bearing and the needle bearings inside it were crumbled and there was a considerable amount of rust-dust.
The bearings made it 133,881 miles, although they were due for a change last year at about 121,000miles. So listen carefully to that old truck next time you're backing out.Don't ignore the truck when it's talking to you, a good sounding truck should be quiet.
