I have replaced my rear wheel barring 2 times in the past 3 months and cant figure out why they keep going out? My front sprocket for my chain moves back and forth could that be causing my problem, or is the sprocket suppose to move? I ride doubles could that be adding to my problem???

 

Would help to know what you have?? Scrambler ,Trail Blazer,Trail Boss?? You may have answered your own question on your last sentence! Plus having the chain too tight or too loose, worn swing arm bearings,etc could be a problem.

 

Sorry, I have a 01 Polaris Scrambler 500.

 

The front sprocket will slide a little back and forth on the shaft. If teeth are worn,I'd replace the sprockets and chain, plus I'd check the swing arm bushings and bolts to see if swing arm is tight. These bolts can loosen along with bushing wear. Just jack the machine up at the rear of the gear case and see if the swing arm has any side to side play. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
