I broke my trucks front wheel drive and he smashed the back of it too.The 2000 gmc crew cab dually.It is the same body style of a 98 GM.it must have a broke pinion shaft because it drives down the road spinning to front axles with just a little rattle I just can hear.I think if it was broke anywhere else it would get bad quick.I'll have to get a manual on this front end.When I was young I just tore what ever I broke apart and learn fixing it but I need this truck everyday so I need to see what i'm getting into.lol <img src="/forums/images/graemlins/smile.gif" alt="" />
