@gunrunnerjohn posted:I don't think it's likely that the drivers are out of quarter, but I will say that you can see problems in one direction if they are. I have a JLC Allegheny, I see no issues in either direction, so it's certainly not universal.
My suspicion would be looking at the driveshaft dogbone, those are sometimes an issue.
I plan on doing a bunch of testing and experimenting this weekend. I know I kind of hijacked this thread but hopefully it helps with future searches having it all in one place. Didn’t seem worth it to start over with a new thread.
