Shoutout to the guy who told me to swap my diff fluid at 60k miles
I used to think diff fluid was a 'lifetime' thing, but a mechanic at a gas station in Amarillo told me to change it or risk grinding noises. Sure enough, at 62k miles, my rear diff started whining on the highway, and swapping the fluid fixed it completely. Has anyone else had a mechanic give you advice that felt overkill but ended up saving you money?
