Check the yoke bolt for tightness! And yes you can remove the rear lid and check the range bolt as well however it is a sign the range pack is failing!

Ok ill start there, maybe its not too bad….yet lol 

New here, picked up a 91 ch613 gold dog,  shes old and shes grumpy lol so comin down off from hi range to low range it grinds into position, i was reading something about taking airlines off and sprayin a little wd40 in or something about a nut that comes loose on the forks or something. Common issue from what im reading. Any thoughts???
