Had same thing in my old 2013 with Bilsteins, I just sprayed it as well and it went awayhas anyone experienced upper noise by the bushings like creeking,2014 150 ecoboost platinum,65,000 miles with front level bilstein shocks.i sprayed triflow all over bushings and i think it cured it.are they shot or what.
I’ve never heard a grease fitting called a zert before. Is that real or a typo? Something new everyday.I've had to lube mine once and it was definitely the aftermarket upper control arm bushings. They squeaked like a 20 year old Dodge. Lol
Shot a little grease into the zerts and magically the truck got quite after a few trips down the ¼ mile bumpy road-driveway.
