Snate is right on. A bar coming out doesn't guarantee a smooth ride on the way back in.
I had some moderate difficulty in getting the old bars out but one of my new ones is bound up going back in, stuck 1/2 way.
I've been away from the garage for a few days and I've been contemplating ways to get out of this jam...for whatever reason, lifting under the k-member to reduce flex didn't occur to me until this thread. So...that will possibly do the trick. :cool:
My only worry now is if the hammering on the bar (progressing from a gloved hand to a rubber mallet to a sledge hammer through a piece of hard wood and finally a few good whacks with the hammer directly) may have deformed the hex-end of the bar at all. It certainly wouldn't take much deformation to cause a problem.
