Where does the power steering return line/hose connect to on the gear box?

Which power steering system does your vehicle have ? EPS - electric power steering or hydraulic power steering . Do you have a EPS light lit on the instrument cluster ?

Power Steering System Description and Operation (EPS)
The power steering system reduces the amount of effort needed to steer the vehicle. The system uses the powertrain control module (PCM), body control module (BCM), power steering control module (PSCM), discrete battery voltage supply circuit, steering shaft torque sensor, steering wheel position sensor, power steering motor, driver information center (DIC), and the serial data circuit to perform the system functions. The PSCM and the power steering motor are serviced as an assembly and are serviced separately from the steering column assembly. The steering shaft torque sensor and the steering wheel position sensor are not serviced separately from each other or from the steering column assembly. The steering column assembly does not include the power steering motor and module assembly.

Power Steering System Description and Operation (HPS)
The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive, cam-driven.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine
The 2 basic types of power steering gears are listed below:
• A recirculating ball system
• A rack and pinion system
In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft. A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod move the other tie rod.
In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the direction of the vehicle's front wheels.
The power steering pressure hose connects the power steering pump union fitting to the power steering gear and allows pressurized power steering fluid to flow from the pump to the gear.
The power steering return hose returns fluid from the power steering gear back to the power steering fluid reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid cooler.
In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the right and left chambers in order to assist in right and left turns.
Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to one side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or left.

steering rack or gear . 2X2 - 4X4 engine . Depends on steering system .
When you turn the steering wheel, the steering gear rotates the pitman arm which forces the relay rod to one side. The tie rods connect to the relay rod with the ball studs. The tie rods transfer the steering force to the wheels. Use the tie rods in toe adjustments. The tie rods are adjustable. The pitman arm support the relay rod. The idler arm pivots on a support attached to the frame rail and the ball stud attaches to the relay rod.
The 2 tie rod are threaded into the tube and secured with jam nuts. Right and left hand threads are used in order to permit the adjustment of toe.

There may be an issue with a pressure control valve.

The previous owner is an idiot. The air filter may be BELOW the box you are refering to. That hose is the crankcase vent and if thats not connected the engine will pull dirt in through that hose. The box has clips to secure the 2 halves of the box. get a new hose. I would not have bought the van if I saw that hose missing.

REMOVAL

1. Disconnect negative battery cable.
2. Remove sight shield.
3. Remove module bracket.
4. Disconnect No. 6 spark plug wire to prevent damage to wire.
5. Remove radiator fan shroud assembly.
6. Remove top RH isolated radiator mount bracket.
7. Remove remote air cleaner.
8. Remove ignition coil.
9. Disconnect electrical connector on power steering pressure switch at steering gear.
10. Remove pressure switch to allow for tool clearance.
11. Remove screw at pressure switch and return line bracket.
12. Remove anti rattle clips from power steering lines.
13. Remove plastic strap attaching steering gear heat shield to power steering return line.
14. Remove plastic strap attaching lines to transfer tube on the steering gear.
15. Disconnect Electronic Vacuum Regulator (EVR) valve wire.
16. Remove the ground wire from back of engine block.
17. Remove pressure line fitting at power steering pump using a 5/8 inch flare nut wrench.
18. Loosen clamp and remove return line at pump.
19. Loosen clamps and remove return line at power steering oil cooler.
20. Remove pressure line fitting (gold in color) at steering gear, using an 18mm open end wrench.
21. Remove return line fitting (silver in color) at steering gear, using an 18mm open end wrench.
22. Loosen two screws retaining power steering oil cooler to sub frame.

It screws into the port with the nut.

the return line is the one closest to the driver fender and closest to the driver. when box is installed. other one is the high pressure line.

Here is a pic.
