Standard Tools Requirements

The installer is assumed to have a complete set of common installation tools including:

#2 Phillips screwdriver
5/32” Allen key
1/4” open wrench
1/4″ wrench
Torque wrench 0 to 20 lbf.in (0 to 2 N.m), for 5/32” hex bit

Vehicle Requirements

Before installing the MDU-G4 system, verify the following items on the vehicle:

The vehicle’s steering system is in good working order. Drive the vehicle to verify this prior to beginning the installation. There should be no play in the steering and the vehicle should turn proportionally the same to the left and right.
The vehicle’s electrical system and battery must be in good working order.
The vehicle should be fully cleaned before installing the MDU-G4 system. A clean vehicle will improve the overall installation and cable routing

If any issues are discovered with the vehicle, they must be repaired prior to beginning the MDU-G4 installation by a qualified service person for the vehicle.Note: This installation manual, vehicle specific installation manuals, and sub-kit manuals contain valuable information for servicing the MDU-G4 system. After the installation is complete, store all these manuals in a safe place for future reference.

Vehicle Inspection

Before installing the MDU-G4 system, confirm that the vehicle and the vehicle’s steering system are in good working order by driving it around. In addition, verify the following items:

Verify that you can turn the steered wheels from lock to lock.
Record the time it takes to turn the vehicle’s steering mechanism (ex. steering axle, articulation point) from full left to full right and then record the time to go from full right to full left as fast as you can manually. This will be used later to ensure steering performance is okay.
Verify the vehicle steers straight and does not pull to one side when driving in a straight line.
Verify that there are no oil leaks.
Check for loose or worn steering components.

If any part of the vehicle is not in working order, have the system serviced by a qualified technician prior to beginning the MDU-G4 installation procedure.
