To add grease or not to 2023 Micro Minnie 1720FB

[1woodward1]

2023 Micro Minnie 1720fb. Zerk fittings. Purchased in October 2023. 5 trips. Each trip around 300 miles round way. I check tire pressure and loosen lug nuts and tighten with torque wrench each trip.

Next trip is about 800 miles round trip. Should I replace/add to axel grease? I have read that manufacturer skimps on grease. I have also read that it is easy to bust the rear seal by over pumping.

questions

1. How many tubes per axel should i expect to use?
2. How do you know when you are putting to much pressure on the rear seal.
3. What if any brake maintenance should i be doing?

Stop loosening and re-tightening the lug nuts. Every time they are loosened and re-tightened, they require a second re-torquing after 50 miles of driving. After that second re-torquing, lug nuts remain tight.
As to the greasing; are you referring to the zerk fitting on the end of the axle? It should never require adding grease. The axle mfgr, recommends disassembly, cleaning, inspecting wheel bearings annually or at 12,000 miles, whichever comes first.
I had a 5th wheel trailer with the EZ lube axles and never used a grease gun. The annual inspection procedure precluded any other maintenance.
Some axles have automatic adjusting electric brakes, some do not. Both should be manually checked for proper adjustment at 3,000 miles per axle mfgrs, but I only performed the manual adjustment check after the bearing inspection procedure.
