Front upper suspension squeak - need help

Hello wonderful members,

I’ve got a 2008 E350 Base RWD sport (W211). I started to notice an intolerable squeak recently coming from the front passenger upper suspension(100%where I’ve been able to locate the sound). Can’t tell if it’s coming from the upper wishbone control arm bushings or somewhere in the strut. I’m I need of a few opinions on the noise so I’ve attached a short video of the low pitch squeak. Any advice would be appreciated.

Thanks,
Colin

How many miles on it? The clip is pretty short but its likely the ball joints, there are three per side plus the one for the torsion bar link. Could also be the bushings on the control arms making the squeak. Lemforder makes good suspension parts., check out FCPEURO.COM

I have had to use a grease needle to grease my 03's front end for several years now! I use a floor jack to raise the car slightly & take some weight off the front end & then apply the needle to the boots & grease!
Much cheaper than replacing the parts!

98K miles on it with all ball joints in the front replaced within past 6 months or so(ball joint on upper is new as well). Haven't done the upper control arms yet on either side, which may be the next step for me. I was really looking to rule out the strut/coilover because that fix is way out of my ball park right now.

Might go ahead and try this for now to just get rid of the squeak until I get new parts.

What kind of grease/grease needle do you use?
