my car is about to hit the 60k mark and i need to do a tune-up. I plan to drain and change all fluids (except brake fluid as i just changed brake pads and fluid about 3 months ago), new pcv valve, clean throttle body and mass-air, new spark plugs and wires, and new air filter.
also i just recently noticed that my differential has no drain and fill holes in it.
i'm planning on drilling and threading a couple of holes in it (after the cover is off of course). any suggestions on how high/low the holes should be? also i plan on using synthetic oils. either redline oil or royalpurple. which do ya'll suggest? anything i missed that ya'll can think of. thanks.
p.s. sorry about the "ya'll" but hey, i'm from texas
