as mac said the early ones do have problems and my uncle is lucky if he gets 12 out of his on the hwy, he also has had quite a few problems with the 4x4 not working when he needed it most, lets just say in the las 5 years he has had to replace the hubs 3 times. now like we have mentioned if ur gonna lift is just go 97 or earlier it will be alot cheaper since u dont have tortion bars and all that crap which will leave u broke after just the lift and might cost more than u pay for your truck. you know this is the first time i have actually been able to truely help someone on here without screwing info up haha
