Do I need a spring compressor to remove...

.... the lower ball joint and lower control arm bushings? Based on my limited knowledge, I think it's; ball joint:no, LCA bushing: yes.

Not only do you need a spring compressor, but you need a safety chain to keep it from killing you if it gets loose.

Exclamation From personal experiences.....


Although I have not yet even seen the MB Spring Compressor......I have done the entire front end of my current 300D, and a previous 240D......I will rent the proper tool the next time I tackle this job.

I used a couple of different spring compressors, and they all had "issues" in compressing the springs evenly due to the layout of the front end components and the screws that do the compressing.

Speaking of "safety chains".....I had to actually cut the NAPA spring compressor screw with a torch to remove it from the spring (spring out of car) after the compressor slipped and bent itself. I use 600# ratchet straps as safety chains. In fact that's how I got the damn spring back into the car the last time I did Guide Rod Bushings and Joints.

If you intend removing the springs for any reason, I strongly advise doing everything that you even think might need replacing in the next 2 - 5 years......I did every joint and bushing in the 300D's front end....then took it to MB Dealer for investment in an ol' Benz that I have ever made......seriously.

Bottom line....if the spring does get loose while under compression, it can do serious damage to anything nearby, including you and your fingers....!!!

For my '83, it was: LCA bushing, yes, Lower Ball, no (according to the FSM).. but it was easier to remove the spring and LCA and do both at the same time -- it made it easier to R&R the old bushings with a vise.

Its a lotta bolts, and doing them in the right order makes the job go tons faster. As long as the spring is out, do the guide rod bushing too if it needs it.
