Does anyone have any suggestions on where I should start to repair the E-starter on my 03 WR450? Right now it will clunk and spin and while hitting the e-button. Sometimes it engages and turns over, but doesn't seem like that is very often anymore. I am guessing I will have to replace some parts, I just would like to know if this is a common problem with the 03 and if maybe I should go with 04 or 05 parts. I haven't even ripped it apart yet, so I really have no idea what I am up against just yet. Thanks in advance.
