I just had a full service from my local dealer. In the process of changing the rear Dif oil, they stripped the plug (not the threads, but the plug itself) and had to order a new one.

When I got the Grizzly back, it ran perfect as usual, but I noticed that it wouldn’t hold on a hill in Park. As a matter of fact, it would roll forward or backward (depending on which way it was pointing) with a clicking sound.

So now I’m wondering is there’s anything the dealer could have done to cause this. Is there any linkage that they would have had to remove in order to do their service work, like adjusting the valves?

Thanks for any help!
