My friend's Grizz was put into locked front-end tonight and then never disengaged. What's the deal? Is it most likely electronics problem or purely a mechanical problem?

 

Goblin,

We have had this problem with both grizzlies we have owned. The problem usually stems from blowing the fuse that runs to the servo motor used to disengage the front differential. The fuse is located under the seat. Check your owner's manual for exact position to ensure you are checking the right fuse. We also had a problem with the servo going completely out on one of the grizzlies. The contact points in the servo with engage/disengage the differential are less than sufficient. We managed to modify the contact points to ensure they would work properly. However, unless you are a very experienced mechanic, I would not recommend disassembling the servo. There are a lot of very small parts which can permanently damage the servo if they were not put together properly.

Check your fuse and let us know what you find.

i hope this isnt a common problem.

 

I have a friend that had a similar problem once. His came out of 4wd, but the brain still thought it was in diff-lock, so it wouldn't go over 22mph. Can't remember how they fixed it, but it involved taking the sensor out of the differential or something.

 

My buddies Grizzly did that onetime also. It was the motor that engages and disengages the 4wd on his grizzly. We were all riding one day and it just went out.
