Is it proper to give the landing gear grease at various points throughout the range of motion to disperse it somewhat evenly on the screw gears or does it make a difference? Because of the slope of my pad I run my gear through nearly it's entire range of motion every time I hook/unhook so I'm thinking it's a good idea to be sure I'm getting grease on all of the parts.

The trailer is a 2016 Keystone Hideout with presumably the cheapest landing gear they could find. One motor on the driver's side runs both jacks together.

Also, how frequently and how much lube? I've been doing 4-5 pumps a couple times a year at several locations on the range of motion. I'm always wondering if I'm doing too much or too little or just right?

I only grease the pinion gear on top. Best way is to remove the screw and lube it. But that is easier said than done.

Saw a youtube video where a guy took pvc pipe and cut it in half long way, then fill it with grease before feeding it down the landing gear body, running the screw in and out. Still a lot of work, since I would have to remove the entire unit to accomplish this.

One motor for both is industry standard for these type.

For my FW landing gear, I drilled a 1/2" hole in the square tubing near the top and spray 1/2 a can of lithium grease once a year to both sides.

so inside the landing gear is a LEAD SCREW and BRASS NUT... the lead screw is an acme threaded rod, and the nut has the same threads on it.. ACME threads have the ability to handle lots of load... steel to steel would gall under the load that's why the nut is brass...

It's important that sometime during the life of this landing additional grease is applied to the brass nut... I've noticed that new landing gears now come with 2 grease fittings.... one supplies grease the the bevel gears at the top and the second dumps grease onto the platform that locks the nut into place...

I'd personally give both 6 to 8 pumps of grease semi-annually if I used the RV a lot...

Can I inquire how you prevented the drill shavings from entering the screw assembly? I would think they would mess things up in there.

I find it interesting that they don't provide zerk fittings for this purpose when they make them. Ours is 2 years old and has none.

The drill bit walks the shavings up the drill bit shaft, not many fall into the hole. That said, I drilled the holes 5 years ago and have not had any problems. If shavings are a concern, you could tape a magnet on the drill bit shaft to magnetize it or close to the hole being drilled. A grease zerk wouldn't get grease on the screw shaft unless you pumped a entire tube in there. The Walmart white lithium spray grease works good with the supplied red tube, then the grease just drips down the screw shaft to the screw nut.

If this is a Lippert landing gear, the following link provides Lippert maintenance instructions for their landing gear:
