So i recently bought this 07 1500 and I'm coming over from Ford. Looking for specs on U joints as I have a metal clacking sound going low speeds (under 10mph) in drive only. Ive been trying to find the u joint(s) that I need and if I need more than 1. Any help would be great.

Silly me forgot the Specs.
07 1500 140k+ miles
Quad Cab Laramine
2WD
Single drive shaft no carrier bearing

 

If you have a single drive shaft, you have 2 u-joints.

 

Thanks
