P/S Help

I have a 79 F150 that we just rebuilt power steering gear box on - problem is, with front wheels off the ground , it turns great both ways . On the ground is a different story -works great turning right , feels like manual steering turning left !! Any suggestions ?!?!?

It can be a pain to bleed properly.

This is from another thread/post:

Bleed p/s the FORD way and it works every time!!!
1- Hook everything up
2- Fill with fluid
3- Jack up front of truck off of ground (Both front wheels)
4- Disconnect or Disable coil (So Truck CANNOT start)
5- Turn Steering wheel lock to lock about 5 to 10 times
6- Top off Fluid
7- Repeat Step 5
8- Repeat Step 6 (top off fluid)
9- Crank engine over (Ignition Disabled) and turn steering lock to lock 5 to 10 times
10- Repeat Step 6 (top off fluid)
11- Repeat Step 9
12- Repeat Step 6 (top off fluid)
13- Enable Ignition
14- Start Truck and turn Lock to Lock 5-10 times
15- Turn off Truck
16- Repeat Step 6 (top off fluid)
17- Repeat Step 14
18- Repeat Step 15
19- Repeat Step 6 (top off fluid)
20- Let Truck Down off of Jacks or jack Stands
21- Repeat Step 14
22- Steering should work just fine, have all the air bled out and have a quiet pump to boot!!!

Several people on here have stated that even with this method it may take 2 or more attempts.

Luckily ours was one that took only one. It did puke fluid a time or two though. Be ready for it. (rags and more rags)

I hope RockAuto is not changing there policies because I have shipped back multiple items that were wrong for free. I had to use FedEx though.

They are also the cheapest prices on most items with info about what brands the parts which is nice.

Good luck with your pump.
