We all seem to have a problem with bad shaking and/or vibrations at idle after we have replaced our engine mount with a non-OEM mount. There have been people who have tried to figure out a work-around and a fix. Yet, there never seems to be a tried and true solution. Perhaps this is why?

I PM'ed user DodgeCares on here, and he looked something up for me.

Now, here is the reply I received from Anchor, who I believe most of us get our replacement mounts from:
I guess the question now is, what's the deal? I'll be sending an e-mail back to Anchor with the part number to see what they say. I have a feeling I already know, but it couldn't hurt. I will also post this up as a sticky so everyone can take a look at it.

The answer seems it may be: we need an expensive factory mount.

 

Looking forward to seeing if in fact this is the solution to this problem . I guess it's a wait and see? Who is giving it a try? I for one have changed all 4 mounts and still has the same rough idle and shaking. Also adjusted the torque struts to 4.7 inch.

 

No idea who is going to try it out. My mount was just changed 30,000 miles ago, but I will give a factory mount a go when it's time. However, the only people with this problem seem to use an aftermarket mount. It's not too often someone with a good factory mount says they have bad vibrations and such.

 

Wish I had known that before doing the motor mounts . But then again I'm thinking how we gonna know? What are the chances people have changed both? I'm first in line to see what in fact the solution to this problem is. I've been at it for awhile and it's the only bad part of this car so far, besides the battery cables being cheap too.

 

I can say, that in 70,000 miles, I'll know because I'll be buying a Mopar mount unless I hear otherwise about the real problem. I just keep going back to it though. The cars don't have the problem until the [factory] mount goes out, we replace it with the aftermarket mount that is almost 1/3 the price of the OEM one, and we still have the problem. I know you have tried things to fix it. I've messed with things here and there. We are still at 0 on the successful attempts, lol. This is the one big thing that I absolutely hate about the Neon.

 

Darth,

If you want to continue investigating this seeing as how I won't be using these mounts or this paticular style much longer you can try mine out.

I have both OEM chrysler AA and AB part numbers both in excellent condition that I could lend you to experiment with.

 

I'm just curious at this point if an actual OEM filled motor mount (not the torque strut mounts, as those are just rubber) is the solution to this problem. It's understandable that people have bought the $40 aftermarket mount in place of the $120 OEM one, but apparently the aftermarket mounts aren't the same. I'm not looking to change mine out at this time though, thanks. I'm dealing with a heater core issue on another car at present, lol. Curious though, does the motor mount seem like it might be filled? Not just like a chunk of solid rubber?

 

It does appear to be somewhat different.

See if i can get a hold of a decent camera and snap some shots.

 

+1 on the waiting list on the solution to this. Replaced my timing belt recently and did motor mounts at the same time. Now I have a bad vibration and I'm not sure if the timing is off or if I was off by .0001 mm on my realignment of the mounts.

 

What brand mount did you use, out of curiosity?
