Popping sound won't go away!

[fordfan99]

I am trying to diagnose a problem with my 99 AWD exp. From a parked position if I turn the steering wheel completely to the right as I am slowly moving forward I hear a popping sound coming from the left front side of the truck. This also happens when the wheel is turned to the right in reverse. Left and right upper and lower ball joints have been replaced and the sound is still there.

If you are turing the wheel ALL THE WAY, maybe you just need to apply some grease to the steering stops on both spindels....

Hey, thanks for the reply TBIRD430, what dya think about it being the half shafts? ive even been told after replacing the ball joints that it could be the cv joints? I will try your suggestion and let you know

[TBIRD430]

I've never owned a 4X4, so I don't what to mis-inform you. Maybe another 4X4 owner will chim in soon...?

I was going to skip this thread, but figured I would read it and maybe learn something.
Tbird430, I think you hit the nail on the head.

Yes it sounds like a bad CV joint.

CV joints can wear out and still have perfect looking boots.
