My magnun had some issues last nite...I was driving & slowed down to turn & the rear end locked up.. then would not move.. the 4X4 locked in without the switch on .. the speedo stays at 30-40 mph even when stopped..It bounces back & forth...I can put the bike on a lift &the rear wheels wiil turn but not fast & I can see the rear end is working..it looks like the axel is slipping.....when put back on the ground it sounds like the rear end is slipping...sometimes it will catch & pull the bike...Any ideas would be great...THanks
