Still looking for this tool to rent or purchase for a cheaper price. Any ideas?

I guess I have no choice but to pay the money for the tool. Please can some one help me rent one or purchase one of these things less then a hundred bucks. A one time use item for me. Thanks.

Performance Products use to rent tools. You might give them a call.

I am curious to know where you set your rear toe and how you created a square box with your strings.

Inner tire wear, assuming good suspension pieces, is the result of camber AND toe. If you have zero toe and still have inner tire wear you have more camber than you need or are not driving hard enough.

Rotating tires often can mask alignment problems. If you are aligned well for your driving style, you should not need to rotate tires unless you want to go front to rear because your drive tires are wearing faster.

i had the exact same tire wear, untill i realized it was my rear alignment, my toe was off! get the alignment done right!

I used a 5" piece of all-thread, a 41mm socket, a shorted 35mm socket, and various washers and nuts to remove my LCAs. I picked up everything at my local Theisen's for under $75. The hardest part was not realizing the bushings press into the hub carrier from the rear. I snapped two pieces of all-thread trying to push it out of the front side of the hub carrier. Live and learn.

I have align my vehicle for years using string. Its very simple old school way of alignments. A lot of guys who build and race cars use the string to align the vehicle. My inside tire wear is due to issues with my Camber. I have a camber gauge that I use to adjust the angle if possible. My E420 camber is fixed on the rear but the problem is that the LCA outer bushing is worn and will not allow the vehicle to have the proper camber while there is weight on the suspension. If the vehicle is up in the air and suspension has the weight the wheel angle is perfect with not alignment problems. Once there is any weight put on the suspension the toe is correct but the camber becomes off. As a result the LCA out bushing forces the wheel to tilt inward and cause tire to wear uneven. Removing the bushing and replacing it with stock new bushing will correct the camber. I have read in the past that some people W124 correct there Camber problem by installing a shorter LCA like the BMW E36. Usually they had to get a shorter LCA because of modification to suspension such as lowering the vehicle. I have not modified and only upgraded my wheels to 18" about 11 years ago. I had no where issue until about 2 years ago.

Finally did it!
 

The tool make the bushing removal super easy. Once I applied the tool it was no more then 3 minutes and the bushing was out. I strongly recommend this tool, it is worth every penny.:)

I put a little grease where the bushing would be install and use the tool to press it into place. That is the grease you see around the newly install bushing once put into place. The bushing tool is a must have for this job. I only wish I had it sooner. No lie, it takes less then 5 min with the tool.

You should have used the OE Lemforder brand of bushing, not the cheap junk Meyle brand.

I'm not aware of any "adjustment" method for a stock rear suspension other than strut or bushing replacement (unless you buy eccentric bushings). Have seen very favorable results by replacing worn "stuff".

Gerry, good to hear from you!

Gerryvz & Hanno, Thanks for the tips. I was not aware that Meyle was a junk brand. I will keep my ears and eyes on the bushing.

Are you saying that Lemforder manufactures the OE bushing for Mercedes?

I need to replace both my outer and inner bushings on my rear lower control arm. I was able to locate the inner bushing in Peachparts' online catalog, but not the outer. Can someone please help direct me to the outer bushings.

Thanks.

Just take a look at the photos I posted. The bushing is located on the rear wheel's knuckle at the bottom which connect to the LCA.
