Yea that could defenitly be the problem.
I would go new, toyota OEM are pricy ($100) but worth it. Are you planning to go to Dual Tcases any time soon? If so I would recomend a set of the rockstomper engine mounts. I could tear up a set of stock mounts without trying in my truck before doing them. Yes you do get more vibes in the truck, but the peace of mind is MUCH better.
