I have the same year model Sidekick and have experienced this problem-TWICE! And good luck finding an alternative. The problem is the permanent magnets used for the motor field detach from the motor housing and shift around, typically breaking up and binding the rotating element, a.k.a. the armature, producing that irritating screeching sound. Eventually it will become so bound up that it will not operate at all. If you know how it is possible to replace the magnets but in my experience this is only a temporary fix but the two times I did the replacement, it bought me 4 or 5 months to save up the money for a new starter I just recently purchased the newer part number starter but have yet to install it. Hopefully Kubota has corrected the problem, hence the new part number
