(in the introductory voice of Rod Serling)*
This all happened probably 20 years ago, but when I detailed my tribulations to a now-defunct Mercedes-Benz internet list, I achieved my Internet 15 minutes of fame. I was known far and wide as “that guy”. I have, for much of my adult life, derived some pleasure and satisfaction in fixing things on my own cars – starting with my 1967 Camaro back in the late 60s.
But lately, with my accrued years, I am seeing the wisdom in letting a pro, with the proper training, tools, and a lift, just do the job.
This attitude started, I think, when I changed the motor mounts of my 1996 Mercedes SL500. The car was on jack stands, I am on my back for a week cursing all the junk I had to get out of the way, just to replace a simple motor mount secured by 2 small bolts on the bottom, and one bolt on the top. And of course, with it all apart, you aren’t going to throw the parts in a box, tow the car with your tail between your legs and plead with a shop to fix your mess! You are committed to finish it one way or another!
I was saving close to $1000 in labor costs! These days I think I’d be glad to let someone with the proper tools do it.
Today’s cautionary tale involves another set of motor mounts on another car. It was a 1986 Mercedes 300E. There was no “junk to get out of the way”, being a simple inline 6 cylinder engine, just a stubborn bolt that would not move.
By the way, the reason these had to be changed is that Mercedes has fluid-filled mounts, to cushion the vibration of the engine and over time and miles, that fluid will dissipate. When you notice a vibration at idle, that is usually a good sign that they need replacing. I can’t speak for the rest of the automotive world, but I believe most of these mounts are solid – rubber?
