Time for a new power steering pump.
I have a 1956 Chrysler "HEMI" 354. After replacing one hose on the power-
steering system, a loud moaning and groaning developed. It's a steady noise
while the motor is running and the car is in Park. While I am driving, the
noise disappears. Any suggestions, please! -- Ed
RAY: Well, Ed. Any time I hear a moaning and groaning noise, it's usually
one of my passengers. And it's usually due to my driving.
TOM: I think it's your power-steering pump, Ed. You probably replaced the
power-steering hose because it sprang a leak. And while the system was low
on fluid, my guess is that the pump got damaged.
RAY: And the only reason it "disappears" while you're driving is because
you can't hear it over all the other road noise and the roar of that HEMI
engine! It's probably still there.
TOM: Start searching around for a power-steering pump, Ed. By the time you
find one, this one should be good and ready for retirement.
