TL;DR
05 Neon, deep thumps/thuds over bumps
replaced upper, lower and driver-side tranny/motor mount (which seems to have stopped the thump/thuds) with AutoZone mounts now causing crazy vibrations which seems to be isolated to driver-side grill and through the steering wheel depending on the position of it
Supposedly Mopar parts, while expensive as all heck are filled with fluid instead of solid rubber
Some/good chunk of people tend to have the exact problem with AM mounts on the Neon
Bad idea to just see if the mechanic can bump up the idle?
Ok, so I have an 05 Neon SXT and just replaced my upper, lower and tranny (driver side, under battery plate) motor mount today due to deep thumps and thuds when going over bumps at ~15mph. Needless to say the upper was definitely bad, nowhere near as bad as the lower (literally was able to push the metal piece that the bolt goes through right out once I got it off) as well as doing the driver-side mount and now it seems like the deep thud/thump is gone when hitting bump but AT IDLE, which I never had a complaint about before, the grill on the driver-side shakes like a bastard, as well as in gear, at idle, depending on the position of the steering wheel that vibrates and shakes like a bastard. Almost as if I let it sit like that for too long something in the steering column will vibrate loose, literally.
I don’t know if having the shop bump up my idle would be the right way to go about it, but it does seem like it idles (as the dodgeforum.com group seems to have an ogoing issue with AM mounts causing the exact problem) real low considering if I turn the wheel all the way to the left the shaking gets almost unbearable, as if I feel like I kept it there the engine would fall through and/or possible stall. Basically just gets really rough.
From what I gathered there it seems like most motor mounts (well, the tranny-side one seems to definitely be the culprit in my case) from AutoZone seem to be a big problem? I should have done a search around before buying them all because with no way to remedy the problem outside of having the shop buy a (Mopar, supposedly the rubber isn’t as stiff and it’s POSSIBLY filled with oil or something since the old mounts definitely were hollow?) mount would suck. AFAIK, AutoZone will only return parts if not installed.
Honestly though, the crazy ass vibrating in the grill wouldn’t bother me (it’s literally the plastic, the radiator, air filter housing, nothing really seemed to be going crazy, putting some pressure on the grill made it stop completely. I could come up with SOMETHING to make that stop but as I said that doesn’t bother me anywhere near as much as leaving it go and having the steering wheel or linkage or SOMETHING in there vibrate loose and/or break.
Would it be a bad idea to have a mechanic up the idle a bit to alleviate the problem compared to eating $35+35+108 that I spent on the 3 mounts? :-/
I’m sure if any of you mechanics and DIYers replaced motor mounts, especially on a Neon with non-OEM ones you’ll most likely know what I’m talking about.

Update: Fixed the alignment of the mounts tonight, vibration is still there. Almost as if (as I suspected, as much as it still needed to be done) it did nothing at all to be honest. Same vibrations are present, etc. Made sure everything was tightened properly, etc.
At this point, I have no idea what else to check. A few different mechanic (not DIY mechanics) literally say “golly gee, never heard of mounts causing that. seems like it’s performance related since it’s at idle/sub 700 rpms. I’d check plugs, plug cables, tune-up basically”. Arg. lol
Hey “Pugtor”, did you ever find out what the problem was? I have the exact same symptoms after having my motor mounts replaced. My mechanic swore he used OEM mounts but prior to the repair there was no vibrations. Now it vibrates exactly like yours. Took it to a few shops but they can’t 100% guarantee it’s the motor mounts or not. They mentioned realigning the mounts but as that didn’t do much for you, just wondering if any progress was made with your vehicle.
Welcome to the forum aww5007.
I strongly doubt you will get a reply from the OP.
He hasn’t visited the forum since June of 2014.
Start your own new thread, add all the necessary details such as the year, the make and model, which engine, transmission–automatic or manual, 2wd or 4wd
Adding which country the car was sold in is also helpful.
