      vibration under hard acceleration

      Idle fine, rev to any rpm, fine, steady cruise fine, light to moderate acceleration fine , WOT I get a vibration, not suspension related it has nothing to do with speed, I can go triple digits no vibration. Only under full throttle starts around 3500 rpm. I'm thinking motor mounts? I already replaced the torque mount. It's coming from the engine bay.

      i get this same vibe under wot sometimes. i thought maybe turbo so i just try to ignore it. but it might be mount related. never touched any of the mounts in the bay.

      Sounds corny but drive with no hood and watch engine movement maybe? Could be mounts I suppose.

      Well,I ordered 2 mounts from IPD, I'll throw them in on Friday. Mounts were my first guess, there are not expensive. I don't really have any other ideas except bad ones, lol.

      I take it aftermarket ones are unavailable? Realistically the lower mount should control the torque of the motor.

      I assume you have the upgraded lower mount (aftermarket or improved factory Volvo) & have already replaced the right upper at least once. You have an 05'... Have you replaced the upper trans mount with the newer hydraulic mount? There were a few posts where I gave the part number for the kit. PM me your email & I'll send the Tech Bulletin.

      Yes I have aftermarket lower mount but have not upgraded the upper mount, I'll see what the motor mounts do first.

      I am having this exact same issue with my 06 2.4i. Only happens under hard acceleration. Is this mostly a motor/trans mount issue? Doesn't seem to be much info floating around about this.

      S40 & V50 customers may complain of a clunking noise during shifting or when applying and releasing the accelerator pedal. It is especially noticeable on cars with manual transmissions during low speed driving and when making a 1-2 shift. The customer may also complain of a slight vibration through the floor or seat at low engine RPMs (approx 1800-2000).
      It's the mount for the transmission. Only applies to early cars, later cars came with the hydraulic mount from the factory. Check your car & compare to the pics below.

      Thanks for posting that! I'm not sure that's my problem, my problem only occurs at WOT and at higher RPM's, right where the meat of the torque curve is. I'm pretty sure the motor mounts are worn and the engine is moving more than normal under heavy load, causing some kind of misalignment, I'll know tomorrow.

      These are factory Volvo parts. Grab from your favorite dealer.
      I can't comment on how effective this will be, just passing along the factory bulletin on a possible vibration source.

      You do know that the lower "torque" mount has been upgraded by Volvo as well? Same old part number, just an improved version with more rubber. Maybe someone could post a side by side picture. I have no idea when the new style lower mount went into production. Anyone?

      ya I think viva or ipd sells the upgraded version. I also recall elevate or soemone carrying there own upgraded version of it using a full silicone mount.

      Your thinking of the upgraded lower mount, which a lot of people have done, the one pictured above is the upper transmission mount.

      Hi all, this is a good topic........i own 2005 v50 t5 fwd auto.
      Experienced the same vibration issue,the only different is the vibe appear during low rpm (between 1500 to 2200 rpm). Have a visit volvo shop, 1st tries they changed both my lower control arm - vibe isuue not solve at all. Next will be the coil spring and the drive shaft change out. For the coilspring i agreed to change it due to the car is too low,suspected previous owner has cut the stock spring. For the drive shaft, feedback from mechanic - theres a minimal freeplay on the drive shaft. Could be this is contributing to my vibe problem?.
      For the transmission mount, Im not sure where is the location of this, can some one here help me by the technical drawing or exactly the picture location? Still much to learn....I am newbie for this volvo ride.

      Clear picture! ! what is on the right one? done check mines, is the same with on the left. I hv changed it a couple of month ago...

      I try to turn the middle drive shaft, heard some 'clurk' sound during initial turn and observed the lower torque vibrated due to the movement of the transmision. It is normal?? How to check the upper tranmision mount? No idea how its look, its below the battery pack...

      Thanks Kova, great picture.
      Mr_V - Yes, it's below the battery pack. Remove with directions found HERE. The right hand mount is an aftermarket unit. Note that it will INCREASE your vibration. The motor & transmission mounts are now both hydraulic to prevent vibration from transferring to the cabin. The "torque" rod has the job of preventing the whole assembly from rolling during acceleration. It's a compromise between preventing moment & not transferring vibration. The original was too soft, too much movement. The aftermarket unit is very stiff, it does a great job of preventing moment in your tuned T5 but it will transfer MORE vibration during "normal operation". The improved Volvo mount will be the best choice for most people.

      Well... both left and right motor mounts are in and problem is totally gone. The upper right was bad, the left hand side looked ok, but I replaced them both anyway. Now I can gun it again without any annoying or possibly destructive vibration.

      The design was slightly different on the new mounts, at a glance the old ones don't look bad, the big rubber pc. attached to the dogbone was intact on the upper right a little tearing on the top , pretty superficial. They looked fine, obviously they were not. I can't post a picture of destroyed motor mounts, because they don't look bad. But rubber gets fatigued under constant movement,
      the bottom left looks new, visual check I would say the old ones look fine. I guess it's something you have to change every so often on the P1.

      Ok thanks for the detail. Are you replacing the mounts at the shop or DIY? Im asking is because of I've worried disconecting power supply from the battery will affectecd ecu or any electronic device.?? Correct me if Im wrong please...
      :facepalm

      i just replaced two mounts a year ago with the new designed mounts. now my car is back in the shop getting all 4 replaced. the tech told me there is a now an even more updated design. so i would suggest replacing all at once.

      Well, I replaced 3 out of 4, to be on the safe side, I'll probably do the upper tranny mount too, although the problem I had is totally gone now.
