:fragez:Ok here we go, I have a 04 500 HO sportsman I took in in the shop to have all 4 struts replaced and tune up oils etc. $1800.00 now they told me the mechanic instaled the left frt shaft wrong when he changed the strut and destroyed it, so they gave me a new one free. Ok now the bike runs fine exept for a noise in the left frt when in 4wd it only does it on severe hills with deep holes like when the wheel is all the way down, it sounds like the gear in the shaft is comming out and skipping one tooth it only does it once each time. I took the wheel off and checked the hub it looks fine nice and tight. My question is could the dealer have put the wrong shaft in (to short) and it is pulling out of the diff on thoes extreme down wheel situations ? Dealer has told me that could not happen that the shaft is the right one. It is strange cause it sounds like it only skips one tooth ? Seems to me if the shaft was comming out it would not just skip one tooth and would not go back in that easy, off the ground jacked up it seems fine but there is no resistance on it, could it be the spring ? shock ? It is not possible to look at wheel on the trail hell I have to hold on LOL. I have not taken the shaft out of the diff as it seems like a lot of work is it possible that it could be pulling out ? Any help would be greatly appricated !!!
