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.

Use this skill when the user asks about accident claims management — first-notice-of-loss procedures, working with insurance adjusters, claim severity classification, subrogation, claim closure timelines, and how to influence claim outcomes. Different from accident-investigation-playbook (which covers facts); this covers the insurance + claim side.

Use this skill when the user asks how to investigate a CMV accident — what to do at the scene, the first 24 hours, evidence preservation, who to call, preventability determination, ELD data preservation, dash cam review, witness interviews, working with insurance + attorney, and how to build a learning culture from incidents. Reference 49 CFR 392.7 + insurance industry best practices.
