still knocking

[Rockhound]

ok, a week ago i started feeling an almost rotating vibe coming through the floor. it happened mostly at initial acceleration and when i hit small, sharp bumps. i checked my tranny mount and it looked like it was quite possibly the bad guy so i had rusty ship me a new one and i put it on. well its still there ( the vibe. ) but i just felt it when i started up an hour ago and i felt it again when i turned the truck off. i just checked my engine mounts and my driver side mount does not look too happy. i'm going to try to get my air box out and take a pic with my digital and post that. if in fact that is the culprit, what is involved in changing them out? it appears to be relatively easy and straight forward, but so do most women. Thanks Guys!!

The motor mounts are not difficult to replace, I've done it several times. I believe I used a floor jack with block of wood against the oil pan to take some tension off of the bolts to get them out and support the engine. I wouldn't recommend the poly. style ones, I tried'em once and it felt like my seat was bolted to the engine! I swapped them out for OEM ones the next day!
