Having some issues with the 4WD on this truck. 4WD works only if I manually lock the hubs which I see is discussed elsewhere in the forums. One particular post details how to replace the stock hubs with a fully manual set.
I am debating what to do about the hubs. Is is worth trying to repair the stock hubs? What is a likely solution? Vacuum line? Dirty mechanism?
I have driven all winter with the hubs manually locked and have had no issue activating 4WD when needed. Are there recommendations or a procedure to clean and maintain the OEM hubs or are manual hub replacements the way to go?
Any advise or links to related forum threads would be greatly appreciated.
