i have a 1993 f150 4x4 and this weekend/week im going to be replacing both front u joints at the wheels, passeneger side upper and lower ball joints with moog replacments and then front and rear shocks. as far as replacing ball joints, i know its best to do upper and lower at the same time, but should i do my drivers side at the same time even though they are bad? just as a precautionary kind of thing? thanks guys!!

 

If yer gonna change half if them...do all of them. They may not be bad now but they won't be far behind.
