L400 lower control arm = mud trap

Sorry for no pix, but bear with me...

So the end of this last Whipsaw trip coincided with an oil change for me, and as I finished up I was congratulating myself on clearing out all of the mud underneath my skid plates, etc.

I was getting ready to put it all back together when I glanced at the lower surface of my driver's side lower control arm.

Turns out, the bottom-side-forward-end of the control arm has an opening about the size of a matchbook (where the welded end of the lower plate ends just shy of the front of the arm). The *entire* interior of the control arm was *completely* impacted and filled with dirt from sloshing thru the mud. I felt like John Wayne's autopsy doctor :shock:

I cleared out nearly a kilo (!!) of dirt that never would have gotten cleaned out on its own from rain, etc.

Just a little heads up if you go playing in the mud; this kind of dirt trap is a real killer for starting corrosion once things get cool and damp.

Another point about removing mud is that it helps to use soap. I power washed the underside and body 3 times and I can still see dirt residue. It really gets caked onto small area's like radiators ect.
