I am new here, but not new to these rigs, or the automotive world. Let me brief you in on my ride and what I have done to it so far, then on what the prob seems to be.
I drive on 05 Ram 3500 diesel, and wanted something for the wife to drive so I purchased an 05 Rango 2wd 4.7 with a bad transmission for her. I replaced the 545RFE with an almost new unit, put new brakes on it, drilled and slotted rotors, ceramic pads, air-raid intake, full tune up, and synthetic fluid in every single lubricated part. I also installed 3" eibach progressive lowering springs in the back, coupled with air-lift 1000 bags in the rear. Lowered the front about 1" via backing the torsion bars off. Painted lids on headlights, ditched the 17's and threw on some 20" rockstars wrapped in brand new NEXEN sport 275's.
WOW what a different machine now! It went from handling like a lifted jeep to a Supra(well not quite, but close
That brings me to my problem. Ever since I bought it, it has had a fairly violent shake that occurs every time I hit a decent size bump, going nearly any speed. It has progressively gotten worse, either due to wearing out more, or my mods, not sure which. I think the 20" wheels dont dampen it like the 17s did. The vehicle is aligned PERFECTLY for the ride height it sits at, and all suspension components have been checked. Everything except the lower ball joints are in A-1 condition. The lower ball joints have zero lateral movement, but about 3/16" vertical play. I am ordering some and am going to replace them, but I would really like to know if any of you have experienced similar problems caused by ball joints? I know that I should start with what I know if bad, but the way it shakes, I have my doubts that it is caused by the ball joints. Any thoughts anyone?....
