Ive had my moser 12 bolt installed for about 3 weeks now. I noticed lately that when I start and stop I get some squeaking...well I found some loose bolts and helpfully tightening them up will do the trick with the squeak. I also have this grinding sound, kinda sounds like that noise when someone is sharpening a knife...any ideas? I havent had very many incidents with vibration or anything but I get the occasional vibration. I dont really want to take it to a shop, but I might have to...any ideas on what the problems are?
