I just bought a my 89' about a month ago its my first t4r and my first 4x4. I had no sound at all from it all the way home and I even moved it around alot the first month without an issue. The noise happened after me feeling my way through the gears with the truck off. I was also going through the 4wd selector. my dad got in after that and i remember him pushing the Clutch start cancel button after two tries because the battery was too low to start it. Then it started making this aweful scraping noise. it kind of sounded like pigs squealing but more scraping than anything. It only happens when the clutch is Disengaged though. off the clutch and the noise stops, back on and its bad sounding. any suggestions. My dad said it sounded like it was just something that needed some adjustment. ALSO! the guy i bought it from mumbled something about the 4wd selector not working and that when he wanted to use 4wd he had to get under the truck and engage it but left no instructions. He said the top loader tranny was newer. Hope you all can help.
