decided to tear into the front end, the Sprague was all to pieces, 1 tooth off the ring gear, and NO fluid in the diff, hav'nt figured out the no fluid yet, don't know how it lasted this long.
I ordered an aftermarket Sprague from superatv, and had to get a ring gear from Polaris, 620$ for parts, will be up and running AGAIN fri, thanks for all the suggestions and advise.
