Hub Grease Axle

Hub Grease is an offline-first trailer service record built for tow-vehicle owners and tower operators. Maintain one named trailer card at a time and open straight into a fullscreen axle-hub dial—so the next bearing repack or aged tire is obvious before you hitch up. THE HUB DIAL Cold start lands on a steel-grey hub face for the active axle. A rotating grease clock shows service status at a glance. Dual due rings track miles and months together. Tire date-code and pressure badges sit around the rim, with brake and light check pips so pre-tow gaps stand out. A hub temperature and notes chip keeps axle-specific context on the same screen. BEARING REPACK LOG Record grease type, date, and odometer miles towed for every axle. Next-due is calculated from whichever limit you hit first—miles or months—so you are not guessing from a paper log in the toolbox. TIRE STATION Log DOT date codes, size, load range, and cold PSI targets around the dial. Age flags appear when tires pass your configured year limit, helping you catch dry rot and date-code risk before a highway failure. PRE-TOW CHECKLIST Run electric or surge brake checks, breakaway, markers, turn, brake, and reverse lights. Each departure save stays with that trailer card so you can prove the walk-around was done. TOWED-MILES LEDGER Tie trip odometer entries from the tow vehicle to a running total since last repack per axle. Miles driven empty or loaded still count against the grease clock that matters. MULTI-TRAILER SWITCHER Name each trailer—16ft utility, car hauler, boat, and more—with its own axle count and hub positions. Flip cards when you change rigs without mixing service history. DUE BOARD & HISTORY See repacks and tires approaching miles, months, or age limits in a sorted list with color severity that matches the dial rings. Review a plain service timeline per trailer—repacks, tire swaps, brake and light passes—and share a plain-text summary of the latest card when you need a shop or partner copy. OFFLINE BY DESIGN Default repack intervals, tire max age, PSI units, and axle layout live in local preferences. No account required for day-to-day use. A seed dual-axle utility trailer with sample repack history and partially due hubs makes the dial meaningful on first launch. See every axle’s grease clock, tire age, pressures, brakes, lights, and towed miles on one hub dial—and get due flags before a wheel fails on the road.
