Not so much that I can't do, but don't have the time to do. I'll probably just stick to doing oil changes for now.
I just purchased this truck, and with 93k miles, I have no idea when all the fluids were changed last. Like to get all the fluids flushed and changed except for the oil. I also don't see myself doing the shocks either.
Without know what has been changed when, I'd rather be safe than sorry with the fluids. With the shocks, it would be nice to have someone reputable look at them and see if they need replaced/rebuilt.
BTW, it is a 2013. Looks like it has been taken care of, but I'm a big believer in preventative maint.
