Hate to ask, but my LC was in for a tire rotation and check front knock noise (over ruts and washboard roads). The shop told me the front hub has sealed bearings and the entire front hub needs to be replaced because of excessive wear and side to side play. I was under the impression the hub was rebuildable. Am I wrong? 144,000 miles and I purchased 9 months and 12,000 miles ago. If they are right, it this time for an upgrade of equipment? If so, what hubs are recommended? Thanks and I did try to research before posting the question. I have 33" tires and a 2.5 OME suspension kit.
