88 comanche 4.0 belt screech
Sounds like a bearing screech the mechanic said it was my a/c eliminator bearing and the water pump bearing so I replaced that pulley and the water pump. Still have the same screech but when I put oil on the belt it goes away for a minute. Could it be a bearing if it goes away when I put oil on the belt?
I also have a '88 Comanche 4.0L and when I first bought it did was doing the same thing. Guy told me he thought it was the water pump but he had just replaced the idler and belt. I also noticed that it went away when you hit the belt with grease or even water. So I left it and drove it. The noise disappeared about a week or week and a half later (about 1000 miles). That was at 185,XXX. I'm now at 190,XXX and I just switched my truck over to a open radiator design like the '92 and later Cherokees had. In doing so I replaced the water pump while I was at it. Now the squeal is back. I think that it is due to the belt just re-breaking in because if I splash some water on the belt it disappears. Plus after a 3 days of driving and 500 miles later the squeal is noticeably quieter but still present. I know its annoying but I'd say based on my experience just drive it.
