Hi,

I just took delivery of some K-Mac adjustable rear trailing arm bushes for my W126.

I Emailed K Mac to discuss the fitting of these, and they reckon I need to pull the entire arm from the car to push out the old bushings.
The WSM shows a tool being used to pull them out, which looks like it could be done with the arm still on the car.

Has anybody attempted using a 'clone' of this tool, i.e. a couple of pieces of tube, some washers and a long bolt?

Any other tips for removing these while still on the car?

Cheers,
Ben.

That is how it is done. A deep socket OR piece of pipe and a STRONG bolt, nut & large washer.

Thanks,

So it can be done on the car then? I dont want the extra hassle of messing with driveshafts, brake lines and cables etc

Do I need to compress the spring slightly?

Ben.

K mac supplies a tool to remove your trailing arm bushings, you can remove the bushings on the trailing arm by dropping the arm down... I will tell you to check the bushings in the kit for fit.. I had to trim them to fit I used a table saw to cut some of the bushing material they were to long.. I can tell you once you get them installed you now align the rear wheels to track straight via tow adjustment an camber will help in tire wear.. Bob

you will have to move the drive shaft at the rear to one side to remove one of the trailing arm bolts.. there is two ways you can move the rear drive shaft. one is to remove the exhaust system an then splash pan to get access to drive shaft. this mean you will have to loosen nuts so you can force the drive shaft of the centering pin an move to one side.. the second choice would be to drop the front of the drive shaft first there is enough play in shaft you can remove it from the centering pin an let it drop down.. all you need to remove is three bolts to remove the flange an leave the flex disc bolted to the trans.
now move to the rear flange an unbolt it from the disc now you can force it off the center pin do to the play in the shaft created by removing the front first.. Its little work but you will not be able to remove one of the trailing arm bolts if you don't do this..You do not have to mess with springs if you do this under the car.. I will tell setting the car up on jack stands at the proper place they should go which is right by the rubber bumpers used for lifting the car. If you put a jack stand there an you should it will hinder removing the bolt on the trailing arm.. you will have to drop the subframe front bolts in order to remove two of the trailing arm bolts. You should do this first set the rear of the car on jack stands an then lower the subframe down to access the trailing arms.. If you have a lift it will be an easier job but it can be done using jack stands Bob

Thanks Bob, I was planning on doing this job over this easter weekend.

They did supply a tool, well if you can call it that. It was just 2 different sized pieces of tube.

I really need to do this job soon, My last set of tires only lasted 6000 miles on the back.
I currently have -2 degrees of camber and 0.5 degrees of toe on each wheel.

Cheers,
Ben
