has anyone in this thread tried replacing the torque converter to solve this problem?
I think the right one ( its hydromount=mount with liquid inside) and rear one is most important, which one did you replace with OEM ?I've thrown a few parts at it including new OEM motor mounts, wires, plugs but nothing I've done has made any improvement.
well, to this comment i should say I've 04 Touareg V6 with auto tranny and there is nothing wrong with keeping car on D + stop light, no low RPMs, no vibes, a missfire is common problem but still no shaking or soi know that the transmission is what is causing it to happen, but i dont know if its the source of the vibration
the vibration clearly comes from putting a load on the engine at low RPM
jrb98391, in the thread about installing a 3.8L throttle body to a 3.3L i had posted some and gotten a few answers about adjusting idle rpm, because it feels like the vibration would be a lot better if the engine was just running a little higher
you might want to look into that and try it to see if it helps
750 rpm is for P and N, but with D or R, 3, L rpms are 600-700 (most typically)I replaced all 4 of the mounts. The rear one was the hardest to do.
The van idles at about a steady 750 rpm. And yes if I step on the gas to increase the rpm, the vibration does decrease. Other than the vibration issue the van runs, shifts great. MPG around 20 in the city, 28 on the highway.
my problem is completely solved after having all four mounts replaced2002 GC 3.8, exact same problem. Ours has been doing this for quite a few years now. Steering wheel and the dash vibrate stopped in D, vibration smooths out when shifting to N or P.
I replaced the easy front motor/trans mount a few months ago. Today I almost ordered the other 3 mounts from rockauto (anchor brand), until I started reading this thread. Now I'm wondering if that would be a waste of money and effort.
I salute jrb98391 for taking the time/effort to document his ordeal, and also a little disappointed in him for not finding the solution! (um just kidding of course for those of you lacking sense of humor).
So I'm happy if I've done nothing more, than at least keeping this thread alive. I'm surprised this issue is not more prevalent.
would this also be seen in the vans hesitation or inability to lurch in drive?I've found that idle speed drops a bit as the throttle stop wears. A low idle speed can produce noticeable vibrations.
Your power steering 'vibration' does the power steering 'groan' at idle?I believe I'm having the same problem as the original poster. 04 caravan se with the 2.4 L 4 cyl. Put car thru maryland inspection. Had to replace front motor mount, both front sway bar links, new brake pads on front, and was asked to clean my rack and pinion cause it was wet and he wasn't sure if it was leaking or just oil leak from engine that ran down. While cleaning R&P I briefly heard a buzzing sound. After I finished I started the van and had a vibration in the steering wheel. No vibration in motor or chassis only steering wheel. Vibration goes away as soon as I start driving then returns when I stop. I'm convinced the problem is coming from my steering system after I cleaned the R&P. I've replaced those parts on other vehicles and never had the problem before. But I've never had to mess with the R&P. Is there something that can be accidentally adjusted in the rack and pinion system or a sensor that could be affecting it? Can't find anything in the Haynes manual about it. Didn't have vibration in steering wheel before the repairs.
