On your '95 Dodge Ram 1500 the front wheels will not turn in four wheel drive why?

Answer 1

THE FOUR WHEEL DRIVE IN YOU TRUCK IS ENGAGED/DISENGAGED BY VACUUM LINES,START ON THE FRONT AXLE.THERE IS A BOX THAT HAS A LEVER INSDE THAT LOCKS THE FRONT END IN AND OUT.YOU WILL SEE THE VACUUM LINES COMING OUT OF IT,JUST TRACE THESE LINES BACK TO THE TOP OF THE TRANNY,CHECKING THAT ALL SPLICES AND CONNECTIONS ARE GOOD AND THE LINE HAS NO HOLES.I HAD THIS PROBLEM WITH MY Dodge AND FOUND A HOLE RUBBED IN ONE VACUUM LINE WHERE IT GOES ACROSS THE CROSS MEMBER UNDER TRANNY. YOU CAN CHECK FOUR WHEEL DRIVE BY TAKING OFF VACUUM LINE ON FRONT END AND BLOW AIR IN THE LINE COMING OUT OF THAT BOX WITH AN AIR HOSE(20-30 PSI) IF FOUR WHEEL DRIVE ENGAGES THEN YOU HAVE A LEAK OR SOMETHING IN YOUR VACUUM LINES.
