poly mounts

So i just installed an s60, poly engine mounts, torque arm, lca's. I already had a poly trans mount and no problems. well after 100 miles of driving to break in the rear end I'm starting to get a vibration in the car between 2,200 and 2,500 rpm in any gear. I'm thinking maybe because I have poly engine mounts and a poly trans mount? Anyone encounter this?

Any chance you clipped a tire or something. Might want to check it out make sure there balanced. Had that problem a while back, very similar only shook between certain rpms. Worth a shot at least.

I'm assuming you went to a S60 from the stock 10 bolt? If so, the S60 has larger axle tubes, and will raise your rear end. You might want to consider the heater hose mod on your rear springs to get it back to where it was. I have a S60 myself and as soon as I installed lowering springs in the rear all my vibrations disappeared.

I'll have to check tire balance and looks, they are new m/t drag radials. Only 180 miles on them along with the rear, but sounds similar! thanks.

And I did do the heater hose mod when I installed the s60. thanks.

I have poly engine mounts and a tranny mount. If I give the throttle a blip, I get a little vibration around that RPM range....

Really? That makes me feel better!! Haven't had a chance to look it over real good yet and going to check a few things to make sure anyway. Trouble is that I changed a bunch of things at one time and noticed this vibe. Had a feeling it was the polys but who knows. The wierd part is that I didn't notice at first and it took 100 miles befoire I noticed. If its normal then I have no problem with it. Hopefully I'll get to it soon
