IM NOT SURE WHERE TO POST MY QUESTION, MAYBE THIS IS IT. I HAVE A 2007 FORD F450, AFTER GETTING IT BACK FROM A NOT SO GOOD SHOP FOR AN ENGINE SWAP, THE POWER STEERING WAS NOT WORKING RIGHT AT A STAND STILL POSITION OR EVEN WHEN ROLLING SLOW, THE WHOLE HYDRO SYSTEM SEEMS TO BE MALFUNCTIONING, INCLUDING THE BRAKES. NOW THIS IS WHAT IVE DONE SO FAR: REPLACED HYDRO BOOST PUMP, REPLACED GEAR BOX, LAST THING LEFT IS TO REPLACE POWER STEERING PUMP, BUT IT IS GENERATING PLENTY OF PRESSURE, WHATS NEXT? ANYONE PLEASE HELP. THANKS!!!!
