Yes, pressure checking is the way to go.

Be sure to flush all fluids and change all filters for a baseline. Check steering rack bushings, anti-sway bar bushings and links, and upper links per the FSM. I am sure you know how to check ball joints.

Extracting the R134a and lubricant, replacing the drier, and refilling per FSM is good too if you have the technology and expertise. Adding a B&M 70268 or 70264 ATF cooler is highly recommended for longer ATF life. www.summitracing.com

Call Infiniti of Scottsdale for OEM parts. Great service and you will save a ton or at least a little if you get trade discount from dealer as most charge over recommended list.
