Record by record
7 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.
Component named as the cause
How it is said to have ended
- result not stated2
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesGrease seen at front hub bearing seals (normal purge, do not replace)1
Manufacturer communication2004–2006 GMC YUKON DENALI ・ 2017-08-15
Front hub bearing grease leakage preliminary information
1Fault
- Grease may move radially outward from the bearing seal area onto adjoining components.
2Finding the cause
Possible causes
- The factory grease fill of the front bearing/hub assembly is more than the bearing needs for lubrication over the life of the vehicle.
- Part of the grease purges through the self-venting bearing seals during the initial drive period (a few thousand miles/kilometers) and helps form an extra barrier against contamination.
Steps to confirm (in the document’s order)
- Replace the bearing if its endplay is greater than 0.005" or 0.13mm.
- Replace the bearing if the seals show visible damage.
- Replace the bearing if it rotates roughly.
- Replace the bearing if it makes abnormal noise.
3Correction
Repair
- 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, and do not clean the purged grease on or right next to the seals, because it gives additional protection.

- Remedy
- This Preliminary Information communication provides information to the technician about vehicles that have grease leaking from front hub bearings. Technician should not replace the bearing for grease purge. Technician should be advised to not clean the purged grease from the area immediately on or adjacent to the seals because this grease provides additional protection.
