Left Cross Strut Failure.... Again!


Replaced the left cross strut to eliminate the dreaded suspension squeak. All was good for a time. Now less than 10K miles here we are again. Any ideas on how to actually fix this?
Pics below are for the left and right respectively.
Thanks,

also, the bolt can be reused. It's keyed, you'll see threads missing once you get the nut about 1 inch off. Line those up after you remove it.
Also use a lift and I have a wagon, so I put a trans jack on my diff and held it aswell, I had to crank on my broken arm to get it to get pressure off the bolt. You may have to do that. Also Sawzall the bushing is am option.



When I have time I am going to take the OEM part and center the bushing and weld the bushing too the arm it self.
Yes Yes...arm was tighten under load not on a lift. Its a simple installation and if need it will also be a rockauto arm going forward.
2014 E63 5 arms at 60k
2014 E550 0 arms at 110k
2014 E350 0 arms at 15k
Its the AMG TQ of the 5.5

if you look at E550 they have the arm listed but remove it from E63

low voltage.
clean the area.
tack and let cool. rinse and repeat.
I didn't do it completely around, just in five or six spots so the sleeve wouldn't move within the arm. Also, didn't want to ignite the bushing.






I'm academically curious if something else failing/wearing out might be aggravating it, or if it happens to be a case of the engineers who designed the car not taking our fat asses into account when designing the suspension.

I honestly always noticed the 'its failing' squeak when I was getting in and out of the car... 6'5 330lb... lol and it does always fail on the driver side...🤔.

Age alone and sometimes lack of driving it deteriorates these parts
