Idk maybe. It has started knocking, well more of a tapping lately. I'm 99.9% sure it's the dreaded flex plate issue and not the motor. It does not act/sound like the motor at all. But I haven't had anytime to mess with and doubt I will even bother fixing it. I am considering selling it soon to add to my wrangler fund. If your interested PM me and we can maybe get up after the holiday weekend and discuss it after looking at the jeep. It needs a good cleaning.
