Mine bought at a discount at tractor supply due to mice chewing the insulator off lots of wire at that feed store. Anyway I’m not even sure 4WD worx but I change the battery because it didn’t have the amps for the EPS or my fan to run all the time or the electronic fuel management system that will run badly with low voltage. So far it’s fine but it’s still flashing codes that don’t show up in the book. Steering is fine. With a 100$ battery that has almost twice the amps of the original. Lots of unique problems with mine due to exposed wires still I’d say.
