Hey guys I just took a trip to ga. n I checked the oil before I left n the oil wasn't even on the dipstick, I put in two quarts in it came up bout half way in the safe zone. When I got back I took it to the dodge dealer for a oil change n a 23 point inspection, this is wat they found,

My truck is a 02 quad cab 1500 4.7 2wd:
Front crankshaft seal is leaking
Valve cover gasket is sepping oil out
All four ball joints need replaced
N the water pump needs to be replaced

The truck has 215000 miles on it so is there anything else I should do or replace with I'm working on it. Also how long should it take me to repair these things n is there anything I should watch for.
Thanks
