I was talking to one of my customers today and we were talking about our trucks. Steve has a 3/4 98 QC v10 4x4. I was saying that my truck was squealing when it was cold and I thought a pulley or pump was going. Steve laughed and said he had replaced his tension pulley and the squeal went away for a few weeks. He said to spray WD-40 on the pulley and the noise would probably stop, this will last for about 2 weeks. So I went home and started her up. She was squeaking a little as usual, and of course my WD-40 can was missing the top so I turned the truck off and put a few drops of 3 in 1 oil on it. I started it back up and she's been perfectly quiet. Is this common for 98s or can we use tension pulleys from newer models or ?
