Yes I know, this a dead horse. 2004 Titan LE 4x4 Crew Cab. My right front is popping only when accelerating from a stop. It's clearly metal and only front right, and I can feel it in the floor board. I have made and installed the spacers for the lower control arm, new sway bar bushings, new links, new struts. I have checked motor mounts and trans mount all are newer and look fine, I highly doubt it is those since I can jack the truck up and drop it and feel the pop in various parts on the right side which is making me scratch my head. My next move is replacing the lower ball joints and the sway bar links again, though they both seem solid when using a pry bar today when putting the spacers on the control arm in. I am also planning on new upper control arms shortly, then maybe the CV axle, I already replaced the drivers side CV axle. Has anyone found an oddity that could be causing this? I have not found any witness marks of anything hitting or anything loose or flexing out of the ordinary. The transfer case is out of question also as it is in 4x2 when it pops.
