Timken: Decided to post new thread in case others may have experienced this. I have complained that the hold back on my wolverine was not doing its job. Before going to Hatfield's this trip I change my oil and both differentials and did nothing else. As we started out riding I put it in 4 wheel drive as usual, and as I started down a steep hill I noticed a distinct difference when I let off the gas it was holding back like never before and continued for the rest of the ride and in low range 4 wheel never had to hit brakes at all, it was great. WHAT COULD OF CHANGED IT??????
