I do not have the details, but once beneath the car, its quite obvious.

But, its rather dependent on the model of your car, and if the exhaust
gives you trouble of getting the bolt out/in on the upper side.

My M119 (500), was easy after removing a shielding plate (for the
starter or the smog pump, don't remember).

You should also lift the car in a way, that you are able to turn
the wheels freely, to get different clearance to use the wrenches.

You should also make sure, that the idler arm has no slop in its
connection to the tube, so that you do not alter the connection position
when moving the assembly out of its normal position to change the bushings.

All in all, a rather rewarding job.

Edit; And have a look here;

You will have play in the steering system, and when you are moving the wheel back and forth while looking at the idler arm, you will see the arm itself rock back and forth. This will tell you that the rubber is worn out.

I replaced the kit in my 190D recently, and it was fairly straight forward, once I removed the dust shield. The most difficult part was getting a long screwdriver in place through the bottom bushing to tap the top bushing out.

Does the car have to be on to check for this play?
