1984 300sd ball joints replacement

Hi, I just bought a 1984 300sd w126 and the mechanics told me I have to replace the front ball joints... Since I have repaired the sunroof of my car thanks to mercedessource, I was wondering if I can replace myself the front ball joints. In this case, which kit do I need from mercedessource? I found a front arm bushing replacement kit and manual but I don't know if it s what I need... At low speed, I get some clunking especially when I drive over bumps... Thanks Erwan

I recommend a good front end shop

Hi Erwan, In my humble opinion I do not consider ball joint replacement a do it yourself job. I do not even do it in my own shop (ie shops that do it every day can do it a lot faster!). It can also be very dangerous if you don't have the correct tools. You do not need a Mercedes shop to have this done. Any good front end shop should be able to do it in less than two hours.

From my experience on 126 chassis, front end clunking is almost always the support rod joints. CLICK HERE to view my replacement kit. When ball joints start to go they sqweal when you turn the wheel or front end moves up and down. Email sales@mercedessource.com if you would like a quote on inexpensive ball joints.

Lower ball joint replacement

Lower ball joint replacement requires compressing the coil springs with a special tool. If improper tool is used or something goes wrong, there is enough energy stored in the compressed springs to do cause a serious injury or worse. I agree that this job is better left to a properly equipped shop. I have been quoted about $ 250 for both lower ball joints on my '85 300D.
