WJ Motor Mounts
I'm not sure if I need new motor mounts but when I come to a complete stop and just idling I get a constant vibration throughout my vehicle. Could that be worn out motor mounts or transmission mount? my wj has a 132k miles on it.

It's best to replace all of them at the same time. Look at them and make sure they're bad before you lay out any money.

Old fart with a wrench
Okay, I'm having the same problem and here's what I've done so far. I had my WJ in the tire shop for new rubber and the tech tells me my passengers side motor mount was broken and my steering damper was leaking. There was no vibration at this point. I replaced BOTH motor mounts and the damper myself and I used Anchor mounts and a Monroe damper. Soon after, I started hearing what sounded like the tailpipe rubbing on the body so I replaced the transmission mount and checked the exhaust system. The heat shield for the converter was loose so I removed it. It was quiet for one day. I put it up on the lift to investigate and found nothing wrong but the sound went away for another day. It seems if I let the suspension hang free on the lift, the noise disappears for a while and the cause is driving me nuts!
My mechanic is a long time friend but still won't allow me to stand under my Jeep when it's on the lift because of liability, so I'm working with someone else's eyes. I have found that when the vibration is the loudest, if I turn the steering wheel,the vibration gets very loud. I'm thinking I've got to check my control arm bushings and the trackbar, but it's been so cold lately, I can't even think about it. The power steering fluid is a little dark, so I plan on flushing it but haven't done it yet.
That's what I've done so far and I hope it helps you. Let me and others know what you find. This may be a problem common with all WJs. I have 150K on my rig.
The Anchor engine mounts I got from rockauto.com and the Anchor trans mount I got at partsgeek.com

Update on my noise. I just noticed the outer covering of my muffler is hanging down. This might have something to do with my noise.
