Hi, I drive a 97 eclipse rs. the problem is that the car is squeeking from the pulleys. I checked and figured out that it was the the belt tensioner pulley. That thing cost a lot at the dealership so I just put on some grease on the tensioner. That helped for a couple minutes then it starts squeeking again. I also tried the belt spray thing but that didn't help. So I was wondering if there is a way to fix this problem? I don't want to buy a new one cause it cost around $116.

any suggestion will be gratefull.
