Part of the issue may be that there could be 2 issues at work here, and the OP is unable to differentiate them.
Another observation as well. On my 3800'*, the harmonic balancer face isn't perfectly uniform. If I stare at the face of it while running, it does appear to be wobbling. However when I watch the outside of it, that runs the belt path, it is perfectly smooth. The old unit was like this before it failed, and so is the new unit.
1013jesse, what exactly are you looking for help diagnosing in this thread? The groaning while turning? Was the 'wobble' simply intended as an observation to try and help diagnose the issue?
