I have a 2009 Pilot AWD that has a noisy transfer case bearing(I believe). It has a constant whine at road speeds. I replaced the transfer case with a used unit from a junkyard approximately 10 months ago. The noise remained after replacement but was about half as before replacement. The noise has increased again since the replacement. I see that RockAuto has bearing replacements for the transfer case. Has anybody ever replaced the bearing inside the transfer case? RockAuto also has shaft repair sleeves listed and wondered if anyone has had use those. Is there a bearing on the transmission side next to the transfer case that could be bad? Any info would be appreciated!!!
