Ok guys i need yer help here. My dad used the 4wd in his truck for the first time since winter last weekend and apparently theres a clunking noise whenever he turns to the right in 4wd. He told me that him and his friend think it might be the original 6yr old shocks binding up or something like that, but we do know it could possibly be the u-joints on the front axle. Hmm, thats odd, my uncle replaced those last year. Either its the 6yr old shocks binding up, or the u-joints were either done wrong or cheap. The truck is a 2005 Dodge Ram 3500 Cummins. Its solid axle front and back with coil springs up front. Help me out cause he wont let me take it mud boggin until it gets fixed! lol!
