Power steering whining
Hi,
I just replaced the power steering gear box on my truck. When I have the wheel turned all the way in either direction it starts squeezing/whining. The pump has new fluid and is filled to the right level, does any know why this is happening?
Thanks

If you have it against the stop there will be noise as the pump is being over loaded such as if it was low on fluid. Rule of thumb don't do it.
If the pump doesn't make this noise in normal driving and steering but only does it at the steering stops that is normal.

It is. Whats happening is the pump is trying to apply pressure but it cant as the steering stops are stopping it, thus the pump loads up and groans. Its the same as if you had air in the line or low fluid level the pump is loading up so it groans and whines.

1988 Ford IDI I replaced the power steering pump and gearbox about two years ago. It worked fine for about six months. It then started whining again when I am turning into a tight area. I am not turning against the wheel stops. Any suggestions as to why this is happening?

Some people say it quiets right down if you add a half tube of limited slip additive.
(You are using the proper ATF in b your steering pump, right?)
Type F is called for, but Mercon V has superceded.
