I bought a floor jack, a grease gun and 2 pregreased replacement hubs for a little more than having them serviced once. I’m doing it myself now and carry all that in a tub in my truck bed.
I enjoy mechanical maintenance. I may not be a mechanic but I’ve fixed all kinds of stuff at my house. Refrigerators, garage door openers, lawn mowers, plumbing issues and now service my own trailer. YouTube is a game changer in that regard. Oil changes are too cheap to do it myself anymore.
