The suspension is IFS and was replaced with known good A-arms with brand new ball joints and minimally used bushings. The popping happened when I test drove it before purchasing the truck. All replacements and rebuilds came post purchase.
Tie rods were brand new, shocks, and everything else that was rebuilt or replaced. I do have a sway bar to install, so it's on the patio. The only items I haven't replaced are the front cross member bolts, engine mount bracket bolts, and rear trailing arm bushings and bolts.
I respectfully doubt it is IFS related because it only happens under high torque, slow speed conditions. I can drive twisty mountain roads at 50 mph (depending on conditions) and the truck handles great. Steering is tight for a stock manual box, and the stock springs handle great for their age.
I wiil find it.
While talking with Pop today, he told me about a new car that was sold at our little Chevy dealer. Had to be 60s or 70s. There was a rattle that could be heard but not readily replicated. Many mechanics looked and tried to find the cause of the noise to no avail. Someone hit the car and when Pop's boss was removing the rear fender he found a can with a note inside it, "You finally found it".
I know this is not from some assembly line worker on his last day, as this truck has lived, it has not been a garage dweller or a trailer queen, it worked and still does. It's a survivor that needs some attention to an ailment that I am trying to locate.
