Have you ever had a bad day at work? Of course you have. Even the coolest jobs have sucky days, like when we have to leave the test cars parked in the garage to get some admin done.
Did you put that on your resume when you went job hunting after being fired so the next employee knew you may be accident prone?That’s too funny lol. We had someone at my work drop one off a Jack and onto the lift arm so it crushed the side skirts, the floor pan, and damaged a little of the fender if I remember correctly. They fired him for that it was his second day on the job too.
I have been in auto repair nearly 40 years and did not know the things you mentioned.You have to strap the front of C5, C6, & C7 Corvettes to the front lift arms when removing the engine/subframe. And the Lift Arms have to LOCK in position when raised!
Same goes for pulling the Transmission/Torque Tube/Differential/Subframe from the rear!
Cheapskate shop owner buying cheap equipment & hiring cheap/unexperienced employees. I worked at a GM dealer when the C5 came out.....If you wanted to do more than basic maintenance on them.....You had to go to training, My dealer flew 2 of us to Detroit. Not that-that would be required today.
We have a Land Cruiser specialist down the street. My cousin told me yesterday that his buddy brought them his 100 series for an oil change. Dude drained the oil and never refilled it and blew the engineAnd people wonder why I change my own oil.
