So, as everyone knows, MB Service quotes outlandish labor times for everything. I have heard them quote 6 hours for a motor mount replacement, and I bet it would be double that if you have aftermarket headers. Well, today my friend and I replaced my drivers side motor mount, and from start to finish it took us less than an hour and a half. And, we did it with one rolling jack, one jack stand, a couple various wrenches and ratchets, a small pry bar, and a couple light sources. This was very simple and waaay quicker than what MB says. The only issue we had was getting the old mount out of the engine bay, which required us to jack the motor up higher and push the motor gently to the passenger side. This was due to my Kleemann headers getting in the way. The mount was totally effed up, and a collective of people figured this to be the culprit in my vibration under the accelerator during heavy acceleration. Negative, once i pulled out of the garage and gunned it...vibration was there, now it is worse

I will get back under the car this week and check the header clearance again, and this weekend replace the passanger motor mount. Anyone else ever have this problem?
