I HAVE A CUSTOMER WHO EXPERIENCES A HITCH OR LUMP IN THE STEERING. IT ONLY DOES IT WHEN TURNING FROM CENTER (BOTH DIRECTIONS). THE CUSTOMER HAD THE RACK & PINION REBUILT. HE STILL HAS THE SAME PROBLEM. THE REBUILDER SAID THE INTERNAL SURFACES LOOKED GOOD AND THE SEALS WENT IN FINE. HE ALSO TOLD THE CUSTOMER THAT IT WAS TESTED ON A SIMULATOR AND THERE WAS NO HITCH DISCOVERED. IS THERE SOMETHING ELSE THAT COULD CAUSE THIS CONDITION, MY CUSTOMER IS BAFFLED. THANK YOU VERY MUCH FOR YOUR HELP.

The only other thing I could think of besides a bad rebuild on the rack is a bad axle.
