power steering/brakes
 

think my pump went out. plenty of fluid. looks to me the pump assist steering and power brakes. the higher rpms the better they work pump or another trick?

may just be air locked, they are capable of that and its tough to get the air out

start it up and at idle with the cap of the pump just turn the wheel full lock both ways, i found when ya get up against the stop just bump it on there a few times

worth a try

if your needing a pump or any other steering components checkout psc motorsports. they specialize in high performance pumps and steering boxes as weel as other parts. they make some upgraded high flow units for the cummins. and they are really nice products. they are the only company out there also that offers a completely new steering box.
