I couldn't turn the hubs to LOCK with my hands. Thought I needed new ones. The 24"+ snow that hit us made me think "I need to lock in the hubs." I took a red rag and draped it over the center ridge of the hub. Got a Big set of Channel locks and open up the jaws. Put one jaw on one side of the ridge and the other on the opposite side. with the jaws on the OPEN position it made the handles almost a V configuration. I DID NOT CLAMP DOWN ON THE RIDGE ,I placeDdthe jaws on their side. I turned them by the handles and whamo they broke loose, reversed the position and turned them back to AUTO. Did this a few times and now they are somewhat loose. What a difference with the hubs locked in. Now what do I use to keep them from not sticking. I did the lube recently but eliminated this part.
