97 honda accord hard steering. power steering pump and rack have been replaced but still have hard steering

is their pressure to rack---also new doesnt mean free from defects can have a failed seal in rack ---air bound

Air in system or damage rack

If you installed a new steering rack, then you
have bad strut bearings, ball joints, & such

The steering is controlled by the steering rack,
& they get stiff because no one changes the fluid
every 3 years

The upper strut bearings fail & make steering stiff

Doubt the pump was a problem at all

Your problem is not the pump it is the steering rack unit, replace it.

Is the fluid low?

Did you replace it with an aftermarket pump?

Aftermarket pumps are notorious for making noise. Your nest bet is to get a good used part or get one from the dealer.

If there is a lot of foam in the fluid it will cause the same noise also. You can add an ounce of seafoam motor tune (available at any good parts store) to the power steering fluid. This will help reduce the faoming fluid.

The last thing I can think of is did you use Honda powersteering fluid? If not your going to want to flush the powersteering system ASAP so you don't ruin the parts you just replaced.

power steering fluid does NOT go anywhere near the boot.but when you fitted a new rack did you turn steering wheel fully left and right several times to prime the rack and then check the fluid.....half a quart is a lot of fluid to add to the system (change your mechanic ASAP)MY BICHON COULD DO BETTER....

hard to steer is not the pump in most cases, it is the power steering rack and pinion steering gear.

Possible the power steering rack is leaking or the hoses going to it.

sadly it sounds like the rack and pinion is going bad..rebuilt units are available ...you'll need a 4 wheel alignment after replacement.  Get this fixed as it very dangerous and will only get worse
