1995 E300D Lower Control arms
 

This car at 225K miles has developed a rather annoying squeeking both at low speed turning and high speed on roads that get the suspension flexing side to side, I got under it yesterday and it seems to be the left side LCA bushings- they are torn and when I move the front end it sounds like thats where the noise comes from.

I did some reading, apparently its more cost effective to get new Lemforder LCA and use a special spring compressor. Anything else I should do while I am doing this besides the sway bar bushings? The ball joints are good, just had it inspected a month ago. Plan on doing both sides.

If the ball joints are good, the boots were available, don't know if they are still.

I think that you can support the LCA, remove the ball-joint locking bolt, then raise the car carefully to let the ball-joint pull out of the wheel carrier, remove/grease/replace the boot (this is how I remember it).

checking the play in w124 balljoints is very misleading, you need to raise the car and rest its weight on the control arms, only then can you lever the hub upwards to check the joint. If you do it with hanging wheels the joint will show itself super tight and perfect.

if the boots are bad, its already game over, replace the joints they are not too expensive either, you just need to make a pressing collar with a grinder or make a whole tool like I did and change them out both. Its not too bad of a job.

its not the balljoint its the bushing where the LCA connects to frame
