Problem is in the rear pinion gears on rear axle and the design of the axle itself. I have a 2005 model 20041 had the same problem. I found a Toro dealer that had the fix.The problem is creadted by the fact that there is too much "play" in the rear axle. You have to limit that play by installing shims, or washers First, but the 2 new rear pinion gears for the rear axle. While you're at it, you may as well buy 2 new rear wheels because the "grinding" has worn the sprockets on the reas r wheels.Next, get 2 "fender washers", 1/2" ID and about 1" OD. I found it easier to turn the mower over and set it on saw horses to work on it.( drain the gas and oil first). Remove both rear wheels, pinion gears and all the washers etc. (caution - keep all parts from one side together - do not pile all parts together - keep them seperated by wheel - the reason is I believe there is one more washer/shim on the right side than on the left). Now to put everything back together, find a spot on the axle where the washer will fit in between the standard stuff.Install new pinion gears and replace the rest of the washers/shims just as they came off. INstall new wheels and you'll be good as new!
