1999 Ford Ranger 6 cyl Two Wheel Drive Automatic
Recently my Ranger started making a squealing noise similar to when the belt is worn, loose or slipping. The belt is a single serpentine belt with the spring tensioner. The belt needed replacing due to wear. After replacing the belt the squealing stopped, for a bit. Then occasionally you will hear a small squeak. I since pulled the idler pulley, and the tensioner pulleys and inspected the bearings. They both were dry and dirty and at first I cleaned and lubed the bearings to see if the problem would go away. I ended up replacing both of the pulleys. The noise seemed to get better but again it would occasionally have a small squeal, sometimes for a couple of seconds, sometime just real brief and have to really pay attention. I didn't feel any play in the water pump, and can't feel any real obvious issues from the alternator, or power steering. When the a.C. Compressor switches on and off there is not any link to the noise there either. This has an automatic transmission, but occasionally the noise reminds me of a throw out bearing. Same similar sound, but there has been an obvious improvement in decreasing the amount of noise and amount of time it squeals with the work that has been completed. Any idea what else it could be?
