Pull exhaust to repair idler arm? Say it ain't so!

It appears that I will have to pull the exhaust system to get the idler arm bolt out on my '88 300E. Does anyone have a trick here? I know full well the answer, but I have to ask the question anyway.

You know, the MB engineers designed this car so that you have to pull the exhaust for a number of commonly wearable items including; clutch, flex discs and idler arm.

These engineers did a very poor job. If they had worked a little harder, they could have made the car so that you had to pull the exhaust to replace the brakes and the spark plugs. I sure hope none of them lost their job for making it too easy to work on.

It appears that without the insane light off converters required by the US Congress in their infinite wisdom, the bolt would clear the exhaust. A German technician never knows that there is a problem.

Thanks for any suggestions you might have. I expect the suggestions will be related to removing the exhaust.

Thanks,

If you take off the nut and pull out the lower bushing, then push out the top bushing with the bolt still in place, it will come right out. Then reinstall in the reverse order, putting the bolt through the bushing before the bushing is pressed into the sleeve.

:p :p

too funny..

Idler Arm bushings

I like the "cut the bolt" idea. That's how a German would do it. Easier than removing exhaust.

Donnie!

You are definitely "THE MAN."

There is absolutely NO substitute for experience. I've said it before and I'll say it again, it's great that you and the other pro's are willing to share this experience with us. We are all most appreciative.

One follow up question. To do it this way, do I need to separate the drag link and tie rod from the arm for this to work?

Have a great day,

From the looks of my car I would say no. I will attempt this weekend. Have nut and heat shield off, will try to pry out bushings and then slide bolt out.

Good luck,
Joel
