I've searched constantly on this site and many others with no luck. I just rebuilt and installed a 6 bolt engine into my 2g. Everything was good and fine until last week when I started to get an awful vibration around 3k rpms. Motor has just under 1k makes on it. Everything I've found on this matter has been related to the balance shafts. I've eliminated that possibility since I installed a bs elimination kit on the rebuild. It'll start around 3k rpms and go away above about 4500rpms. Out does this in all gears and sitting still in neutral. I've checked the motor mounts, transfer case and transmission for looseness, and I have run out of ideas. I read one response from someone who claimed to have had this problem and they said they redlined it to 7500 through 1st and 2nd and it went away. That'll be my last resort as I'd rather fix it correctly and not chance something catastrophic. Thanks inn advance for any and all help. Below is a little info about the build.
