Possible causes

Candidate cause (the documents say what to do)

Grease seen at front hub bearing seals (normal purge, do not replace)

The factory grease fill of the front bearing/hub assembly exceeds what is required for bearing lubrication over the life of the vehicle.

Some grease purges through the self-venting seals in the initial drive period and helps form a barrier against contamination.

What to do

  1. Replace the bearing only for visible seal damage, endplay over 0.005 in (0.13 mm), rough rotation or abnormal noise.
  2. If desired, grease that has migrated away from the immediate seal area can be wiped off.

Caution: Do not replace the bearing for grease purge.

  • A portion of the grease will purge through the self-venting bearing seals for the initial drive period (a few thousand miles/kilometers) and helps to form an additional barrier to block contamination of the bearing.
