My starter did that since augest when I bought it. It would turn the starter but wouldnt engage. Made a grinding noise. Checked the ring gear it was all good. Finally this last saturday I decided I was gonna change it. Called the dealership they wanted $1075 plus tax canadian. So I called autoelectric and got a reman for $220 +tax with lifetime warranty so I was happy. Replacement was simple disconnect batteries 8mm and 13mm nuts on starter wires. and 2 15mm mounting bolts. One exhaust clamp and starter was out. I'd say it only took 1hr total to R+R it with air tools. Look at aftermarket for a starter they come with warranty and are way less $$.
