Steering gear box popping, cracking, sqeaking noise
I am a new owner of a good old 99 f250 PSD. This truck has about 170k and a 4 inch lift and 35 inch tires. I just finished rebuilding the front ball joints, spidle bearing, and replacing 1 axle stub and both hub seals. I have now noticed noise coming from inside my steering gear box i.e; popping, cracking, and sqeaking. While I was investigating where the noise was coming from I noticed that the nut that holds the extended pitman arm was loose, I tightened it in hopes that was my problem but its not, I was wondering if anyone else has had this problem and if it is as simple as replacing the box or something else? Thanks for the help.......
