See the full year list below.

What are signs of a worn front differential bearing?

Whining or growling that changes with speed, oil seeping from the output seals and play at the input or output shafts.

Does it include gears or the AWD components?

No. It is the bearing and seal kit; inspect gears, the output cups and the AWD hub components while the differential is apart.

Is installation difficult?

This is a shop-level job that requires removing and disassembling the front differential with bearing pullers and drivers. All Balls does not publish an install sheet.

Should I replace seals only?

If the bearings are smooth and only the seals leak, seals alone may do. If there is noise or play, replace the bearings too, which is why this kit includes both.
