I bought a 01 Ranger with 177K miles on it a few months ago and decided that I should go go through and tune up the truck. Here is what I have done so far:
Canged/Replace: oil, oil filter, air filter, fuel filter, coolent, thermostate, PCV valve, power steering fluid, rear differential fluid, spark plugs (and wires), brake fluid and transmission fluid.
Is there anything else that you guys think that I should do?
Also my power steering is still whining when I turn the wheel, should I try to rebuild the old one for $15 or buy a new one for $40?
