Brad850 Posted June 9, 2013 Report Share Posted June 9, 2013 Car vibrates BAD in drive while stopped. Rear view mirror shakes, interior rattles. In idle and park it almost completely goes away. As soon as I begin to accelerate the vibration is gone also. Car is just not pleasant to drive at the moment. Mounts less than 1 year old with maybe 1000 miles : Both hydros, front mount under crank, 4 new subframe bushings. (all oem except front mount which is uro) Older mounts around 5 years old: Upper ipd poly mount, qbm poly firewall mount, original IPD poly trans mount. My guess would either be the shitty uro front mount, or the old ipd trans mount. Before I fixed my rms, the trans mount was usually covered in oil. Are my symptoms pointing towards the trans mount? Only thing is... it shifts nice. No clunks going into drive or reverse, and pretty smooth driving. Link to comment Share on other sites More sharing options...
(n)A-GAME Posted June 9, 2013 Report Share Posted June 9, 2013 Likely the transmission mount...PO installed one of the Poly mounts on my R and it's obnoxious. It's actually embarrassing when others are in the car. I'll be replacing with rubber very soon. Link to comment Share on other sites More sharing options...
Brad850 Posted June 9, 2013 Author Report Share Posted June 9, 2013 Yea my girl doesn't like it my friends talk shit and my mom asked me a few days ago if the car was safe to drive . Been going on for a half year at least and it just recently intensified. So a bad transmission mount is likely to transmit vibration in drive but less in neutral? Not many topics I can find on this.

(n)A-GAME Posted June 9, 2013 Report Share Posted June 9, 2013 It's likely not a failure of the mount itself, that's just how the poly mounts behave. In any event I'd start with that one. Link to comment Share on other sites More sharing options...

rmorse Posted June 10, 2013 Report Share Posted June 10, 2013 Have someone put the car in drive, and keep their foot on the brake. Pop the hood, loosen the top mount and retighten it, all while the car is in drive. Link to comment Share on other sites More sharing options...
Brad850 Posted June 10, 2013 Author Report Share Posted June 10, 2013 Got it.. will do that once it stops pouring Link to comment Share on other sites More sharing options...
Oreo931 Posted June 11, 2013 Report Share Posted June 11, 2013 My guess is the front mount (under the crank). Had the exact same symptoms you describe and it was that mount. Link to comment Share on other sites More sharing options...
Brad850 Posted June 12, 2013 Author Report Share Posted June 12, 2013 Re-did the top mount in drive (did nothing). Shit man. Feel like I just bought it. This was before I knew that uro was trash. But thats my guess too adam... it feels like the motor is sitting on the subframe. Think I'm going to buy it tonight, then if that doesn't fix it...tranny mount. And if that doesn't work... who wants my car? Link to comment Share on other sites More sharing options...

And if that doesn't work... who wants my car? That will fix the vibration, trust me. I forgot to mention in my earlier post that this actually has happened to me on two Volvos. Both times it was the mount under the crank pulley. URO is absolute trash. The fact that the mount went bad so quickly doesn't surprise me. In fact, it's expected. I used URO parts on a PCV replacement a couple years ago. I had to redo the entire job less than 6 months later. Link to comment Share on other sites More sharing options...
Brad850 Posted June 19, 2013 Author Report Share Posted June 19, 2013 Replaced front mount... did nothing. Link to comment Share on other sites More sharing options...
KllewT5 Posted June 20, 2013 Report Share Posted June 20, 2013 I had a nasty vibration too, changed the passenger engine mount by the subframe, now it's smooth as silk. Got mine from FCP: Volvo Mount Front Right (850 S70 V70 C70) - Lemfoerder (OEM) 8631698L After spending almost 7K on this car so far, this has been of the best and most satisfying items ($80) i've done. If they made this mount in polyurethane, it'll probably make the vibrations worse. I'd buy one just to see. Link to comment Share on other sites More sharing options...
DAYWALKER Posted June 20, 2013 Report Share Posted June 20, 2013 if a mount fail then it will sag and hit the subframe. so every car is different. while one mount will fix your vibration it doesn't mean it will fix other car. just check which one is bad and change it. maybe there is more than one that is worn out so don't give up.

Brad850 Posted June 20, 2013 Author Report Share Posted June 20, 2013 Yea the only old mounts left are the trans mount and firewall mount. Although one thing I did notice, my new oem front mount was about half an inch higher than the uro one. Had to jack the engine up a little to line up the holes. I spoke to soon in claiming it fixed nothing, the car does feel a little tighter. Link to comment Share on other sites More sharing options...
KllewT5 Posted June 20, 2013 Report Share Posted June 20, 2013 Here's the firewall mount I think is the culprit: CIRCLED IN RED Link to comment Share on other sites More sharing options...
