Wheel-End / Lubricant Inspection

Wheel-ends are a high-risk component. A wheel-off-axle event can be fatal. Inspection and maintenance per § 396.3.

Types of wheel-end design

Oil bath — wheel hub filled with oil, sealed with O-ring
Grease packed — hub packed with grease, sealed with bearing dust shield
Oil-bath with breather — slight ventilation to prevent pressure buildup

What to inspect

Oil level (oil-bath designs) — usually visible through fill hole or sight glass
Visible leaks — oil running down rim or onto tire
Bearing temperature — excessive heat indicates failure
Wheel play — should be minimal
Wheel run-out — wobble indicates imbalance or bearing wear

Lubricant interval

Manufacturer recommendation typically every 50,000-100,000 miles
Different oils have different lifespans
Driver should check oil level at every weekly fuel-and-inspection

Wheel-off cases

A wheel-off-axle event is investigated as:

Manufacturer defect
Maintenance shortfall (bearing failure)
Operator error (overtorque, under-torque on lug nuts)
Overloading

Carrier responsibilities

Maintenance log per § 396.3
Track wheel-end lubricant changes
Lug nut re-torque schedule (typically 50, 200, 500 miles after wheel-off-then-on)
Annual inspection includes wheel-end check (§ 396.17)

Compass tracking

Compass Vehicles module:

Tracks wheel-end maintenance events
Lubricant change scheduling
Bearing inspection records

CFR citations

49 CFR § 393.41
49 CFR § 393.43
49 CFR § 396.3

How Compass surfaces this

Searchable in Compass Ask. Runs against carrier fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.

Install veh-wheel-end-lubricant-inspection and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
