As many have commented, accessing and removing the OEM cap was a challenge. We have the FP/Fox leveling kit which provided enough clearance to work underneath laying on my low profile creeper. I was unable to break the OEM cap loose. Not enough room to comfortably swing a hammer attempting to hit a wrench on the OEM cap.
To go in from the top, I would need to buy long extensions that would likely never be used again.
I turned the wheels full left, removed the liner, then easily removed the OEM cap with a 12" long 3/8 inch drive flex handle breaker bar, 3/4" deep well socket, and 24 inch section of 1/2" steel pipe for reach. My tool collection does not contain a 19mm deep well socket. I used 3/4" deep well. NOTE: 3/4" = 19.05mm
This method provided the best torque angle with plenty of clearance for swinging the bar to the right and easily removing the OEM cap.
For more wire bundle clearance, I did remove the light colored christmas tree fastener below the stick, pushed the harness below the metal attachment tab, then secured with a plastic tie.
