Are Lemforder Engine Mounts Crap?
I bought two Lemforder engine mounts and just over a year later they're less 1/2 way down.
That seems awfully soon.
I went back to FCP Euro where I bought them from and they are no longer listed.
Corteco is the OE and almost twice as much. So much for trying to save money....

At 101,422 miles they were replaced. I have 122,000 now.
I emailed them. Still sucks because I'll have to pay $350 to $400 in labor. They should last for at least 100K right?

Yes for sure. And back when I had the CLK, I replaced the OEM engine and transmission mounts at 100k km with Lemforder ones and by the time I sold the car at 200,000k they were still fine and performing well.
I've never had any problem with a Lemforder part.

Lemförder is about the best you get, besides MB OEM parts. How long motor and tranny mounts last, is very much a matter of how you drive, but only getting 22K miles out of them, is not enough. Even an aggressive driver should expect 50K miles, and the average driver could expect 70K miles.
The best way to check if they are damaged is to open the hood fully, look at the engine from inside the car, put tranny in D, hold down the brake firm, tap the throttle and watch the movement of the engine. The left side should not lift more than 1". Some worn out motor mounts can make the engine lift as much as 4 "
Repeat in reverse. If you can't see from inside the car, you watch from the side, and have a helper behind the wheel. DON'T stand in front of the car.
This video show bad motor mounts, at 1min.35s.
I changed mine 4k ago, took me 4 hours.

Well I did replace a lot of suspension stuff within the past year or so.
Engine Mount Replacement - May 3, 2018
Stabilizer Bar Links Replacement - August 10, 2018
Front struts - August 8, 2019
Rear Rotors (warped), Pads - August 8, 2019.
Rear shocks ordered - TBD
All of which were well past service. I've been driving on bouncy struts for a few months.
Q. Could it be, that combined, this put added stress on the engine mounts? I suppose the parts could be be bad.
I do take corners on the more aggressive side but not like Steve McQueen.

The bouncy struts could contribute to motor mounts wear out. The engine represent some 400 lbs, and the bouncing up and down, would stress the motor mounts, shortening life.
