When I release the throttle at high speeds there is a very loud metal clanking noise as the 4-wheeler slows down. It doesn't make noise any other time. 4-wheel drive works fine. Maybe related to ebs? Also handle bar throbs back and forth. Checked fluid in hubs. Jacked up front and back, spun wheels, found no problem. I'm not sure if both problems started at the same time. Thanks.

 

I would start with the easy stuff first, check all cv an U joints for wear. If that reveals nothing then take the drive and driven clutches apart in the PVT and check for wear also. If your not familiar with the workings of the PVT it might be a good idea to let your P dealer have a look at it.
