Hey guys, I need some of your opinions on Wynn's flushes. I was at the dealer last week getting some replacement bed rail covers and I was looking through their maintenance "menu." I noticed that they have such things as a differential flush, coolant flush, and other flushes.
I plan on keeping my truck for the long term so my question is, how important are these flushes and are they really necessary?
I'd like to keep my truck in the best condition possible but at the same time not spend money on unnecessary things.
