Hey guys, I have a 2003 mustang gt (manual 5 speed) with a little under 44k on the engine. I went to a texaco express lube and was informed that the synthetic rear differential fluid needed to be changed. They advised that the previous owner before had not changed it soon after he bought it and that since I havent had any problems its a good indicator that he didnt drive it much (only had 26k on the motor when I bought it). They advised they could do it for $80 and I got the feeling that they were trying to con me into paying them more money. My question is, do you guys think it would be necessary for me to have this fluid changed out or should I get a second opinion?
Another quick question is this. I got 2 conflicting answers in regards to power steering fluids from autozone and advanced auto parts. One said that I use Mercon V auto transmission fluid and the other said I use regular power steering fluid. Unfortunately I do not have access to my haynes book (another state) and the owner of the car previous to me lost the owners manual. Could you guys help me clarify which is the correct power steering fluid to use and whether you think I should change my rear differential fluid? Thank you very much in advance.
