I’ve got a 13’ Brutus. Absolutely love it and have had it for a little over a year. I’ve noticed over the last several months it won’t come out of 4wd into 2wd unless I go in reverse. It also seems to accelerate slower (notblije they aren’t already slow enough). There is also a slight squeak in the front axles somewhere. It also seems to struggle going up inclines unless I turn the rpms up all the way. I did some googling and it looks like front diffs on the 13’ aren’t all that reliable. Thanks for any input.
