My truck has 108k miles (had 103K when I got it) and has had a fifth wheel in the bed at some point. Being a Laramie SLT (top of the line in its day), I figure it has probably pulled a camper or something big and fancy like that. The turbo was making a shrill growling noise, so it's probably been shut down hot and baked the oil and bearings. I had been contemplating getting a new or reman turbo for my truck, but the cheapest ones are almost $800. I found a rebuild kit for $90 and decided to give that a try first. My friend and I rebuilt the turbo last Saturday and it sounds a lot better. It whistles instead of growling. I snapped a couple pictures of the engine without the turbo and of the turbo sitting on the table. The rebuild went well and I consider it a good $90 and 3 hours spent. We found out that the wastegate is frozen shut, but that's not a problem--it'll actually build a couple more pounds of boost. There is still a noise that doesn't sound quite right, but my friend and I think it may be a charge air leak somewhere (hopefully not the intercooler). The next thing I'll do is replace the rubber boots that connect the turbo tubing to the intercooler and the intercooler to the intake tube. That'll be about another $100 and a few hours. Sorry if the pictures are a little dark.
