Need to replace TPMS sensors

I am looking for a step by step process to replace the TPMS sensors on my G35x 2008. Can anyone help?

Thank you

Guy

If you need the transmitter replaced, remove wheels, dismount the tire from the wheel, unscrew the lock/set ring on the TPMS transmitter, remove.

Clean up aluminum surface with scotch-brite pad on inside of wheel, apply silicone grease to sealing o-ring on new TPMS, torque lock/set ring to 66 INCH/lbs.

Re-mount tire to wheel, set bead, test for leaks, road force balance, install wheel to vehicle, torque lug nuts to 80 ft/lbs.

Recalibrate TPMS either manually by following the steps in the FSM and going for a drive, or by using a handheld scan tool which is substantially quicker.

If you just need the receiver replaced it's just a simple matter of unbolt the rX from the wheel hub, unplug the harness on the other end, route the new rX through the same location as the old one, plug in the harness, tighten the bolt on the wheel hub to 10 ft/lbs.

The front wheels use separate harnesses, the rear wheels use a single harness that hits both pickup rings on the rear differential.
