If only the pressure sensor needs replacement, do not replace any hoses.
^
Always replace both copper washers (mounted at the power steering pump).
CAUTIONS:
>
Do not allow dirt or contamination to enter the hydraulic system.
>
Always secure the pressure sensor mounting block in a soft jaw vise when removing and installing the pressure sensor. Do not clamp onto the "banjo" end of the hose.

Refer to the appropriate Electronic Service Manual (ESM) for power steering hose removal, installation, and torque specifications.
