Front Side Shaft Bearing Premature Failure

Drivetrain - Front Axle · severity: Moderate - a real, documented leak/wear point at the front differential rather than a sudden failure risk, but a genuine drivetrain repair, not a minor item. · confidence: 45/100 · 1 cited source
Applies to: 2.8L Duramax diesel - not every engine this model has been sold with
ⓘ Not yet individually classified

Symptoms to watch for

  • Leakage at the point where the front drive shaft enters the front differential
  • Onset documented as 'premature failure' specifically past the 100,000km mark

What To Check

A leak at the front differential may not be visible without a proper inspection from underneath the vehicle - ask for a lift inspection specifically checking this area, particularly on any example past 100,000km.

This is everything documented for this issue - no repair-cost estimate or TSB/recall reference was found for it, so there's nothing further behind a full report for this specific finding.
