Try this:POR-15 45404 Rust Preventive Coating.it really work for my NV chassis.even after a new York winter.

21mm sure,but the nut material is too soft?some tire shop use incorrect socket and over tight by air gun make it out of shape ,if not too bad try to grind it to fix.

the hole on the rim is enough to rough estimate ,even you go under the vehicle still hard to check it if you don't have experience, if you feel your brake pedal high and firm ,you don't have to worry your brake pads, if rotor is bad you will feel rough or Vibration even you will hear that.

Power stop Z36 is my favorite,much better and durable than oem.

i will direct connect the wire to reverse light socket or the reverse light wire near the socket.

when you replace brake pads,don't forget to service the pin. when you replace rotors, you better clean up the hub and apply some anti-seize on it.

usually brake caliper have two part and 4 bolt. just open up the cover and slide brake pads in.but nv is one piece design and 2 bolt only,so you must take whole caliper off to put pads in, anyway you replace rotors so what matter what design you still have to take it off.

i don't remove the plastic guard ,if your upper body all the way over the filter, you can easy to reach the filter,i put a 2"deep 6"x10" container under the filter to collect the oil,remember don't put the filter in to container,that will no room to take the container out.before you take off the filter,you better find the best way how to put the container in and out.

i use Mobil 1 104361 75W-90 Synthetic Gear Lube LS every 20k because alway heavy load.that need 3 Qt each time.

half time heavy load,half time over load,1000 mile every week,mixed 10.4
