Thats
impressive!
I wouldn’t mind listening to you list what your concept of
preventative maintenance is, because it sure seems to be working for you.
My followup question would be, do you have a lift? I surely would, if I did that kind of maintenance.
According to my wife, it's not really impressive being OCD. Most kids growing up had TV's, something we didn't have in our rural area. So growing up, I spent a lot of time in my Grandfathers shop (blacksmith), my Dad's shop (engine rebuild) and the hired foreman's shop (Farm Equipment Repair). He was a ratrod builder in his spare time. A great teacher of all things mechanical, hydraulic and working with anything with rotating parts (a lot of old farm equipment).
For several years after high school I was an electronic tech and a tune-up scope repairman/salesman, automotive hoist salesman and installer. Had the opportunity to train mechanics how to read the scope and utilize the diagnostic routines. I learned even more from the mechanics than they were really learning from me, so it was a good trade.
In the process of taking trades on automotive shop equipment I ended up with what most would call a complete shop. It wasn't though.
I had a Hunter alignment rack, a 9000lb offset two post Western Hoist. Two tune-up scopes, Accu-turn brake lathe, refrigerant recovery station, etc. etc. Most of this equipment is now at a trade school in Ensenada, Mexico
Preventative Maintenance.. About every 70 to 100 thousand miles I would pretty much go through the suspension, and final drive, replacing u-joints and would re-balance the drive shaft, wheel bearing repack/replacement. I would also rebuild the differential. In between scheduled maintenance there were always small semi-annoying things to work on.
I considered this recreational time.
