Something has been chirping similar to a cricket sounding like its at the rear originally thought it was up front, once i start going around 30 mph it will stop. I have checked breaks, clearance around calipers, axles, brake pads and rotors. I have had the u-joints changed, front and back, new upper and lower control arms and bushings in rear, changed both front hubs/bearings, new rotors, calipers, break pads and made sure there is clearance between front dust plates. I have changed every serpentine bearing, ac clutch and bearing, clutch, pressure plate, throwout bearing and fork. Spider gears are shot in differential and it needs rear axle bearings only because of too much end play on drivers side, could this be the reason or am i missing something?

I usually associate the chirp with front ball joints. If your new upper and lower rear control arms came with polyurethane bushings, they may need to have some marine or bearing grease applied to quiet them down.
