ok guys I have another question . I though I had a loose belt issue so I checked it all out and found the pulleys were wobbly on the bearings and the belt seemed a bit loose so I bought new pulleys and bearings and belt and low an behold its not the belt . I just serviced the diffs last week cleaned em out put new fluid in them and reassembled them the main reason I serviced them was because I thought the noise I heard was a bad tranny gear or something and once I looked at the gears in the front and rear everything looked really good I figured it just has to be the belt well I think I was wrong because if I hold one of the back wheels and goose the throttle it makes a crunching sound from what I believe to be is the rear diff . My question is have any of you had any tranny or diff issues with your truck ? Im alittle upset im going to have to pull the whole back of the truck apart again .lol. I spoke with Chris at AE and he says its probably the idler gear which I wont argue with it just seems like its the diff to me what do you gurus think i value the opinions of you guys and any tid bit of info always helps . thanks
