I still wrench on all my vehicles and a few friends cars at times. I don't know how people can afford to buy new cars and pay for all the maintenance and repairs.
I just did 3 family vehicles last month where all got engine oil and filter change, transmission oil and filter change, air and cabin filters, and steering fluid changed out. All fluids where full synthetic. $400ish for all 3 vehicles, including tax and shipping. 250,000, 130,000, and 80,000 miles. Ready for a hot busy summer of driving now.
I did a rear axle seal and bearing replacement in my Silverado last month too. Which required a differential fluid change and a new cross pin bolt after I found the original had a severe grove worn in it. $100 in parts.
I have fixed water pumps, idler pulleys, thermostat housings, the pentastar oil filter housing, crankshaft harmonic balancer, alternators, batteries, blower motors, blend door actuators, brake pads and calipers, new brake lines, ball joints, steering linkages, u joints, shocks and struts, leaf spring and shackle replacement, window switches, coolant line replacements, radiator flushes.... All to save money to help raise 3 kids. We're at over a million miles on family vehicles since our oldest was born. I've paid for only 5 repairs and 2 deer strikes the last 18 years.
