The power steering box is a 1969 and pump is likely 1975.
When I turn right or left I get a loud squeal when the steering wheel is close to maximum turn. There is plenty of fluid in the reservoir and the truck steers with little effort. Iv'e read where this could be a loose belt or a hooped pump but am not sure its either. Any suggestions appreciated. | | | | | Joined: Feb 2007 Posts: 230 Shop Shark | | Shop Shark Joined: Feb 2007 Posts: 230 | Could still have air in the line. Try turning the steering wheel lock to lock a bunch of times with the engine running. That will drive out any air. | | | | | Joined: Mar 2004 Posts: 6,214 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,214 | My vote is the belt...

When you reach the maximum left or right, there is a huge load placed on the pump. A misalignment of the pump pulley will cause a squeal even with a tight belt.

That will identify or eliminate it. If squeal does not stop, could be air or some bearing. Does take a while for air to escape. Be sure you recheck fluid level!!!!!!

I had painted my pulleys during the rebuild including the 'V' grooves which I think initiated the slippage.
After sanding out the pulley grooves to bare metal (which would ordinarily happen over time anyway) and replacing the belt with another new one i've never had the problem since.
