rubbing/ vibration while accelerating at 2100rpms

[tomkurtziv]

Hi guys. I've been having this rubbing noise and vibration while I'm accelerating. The noise starts at 2000rpms and when i get to about 2100 to 2200 I get a really bad clunking in the passenger side floor and I feel it really good in my pedal. After about 2400 the knocking sound goes away and it just the vibration and it smooths out at 3 and drives fine. I noticed it's the worst when I'm turning to the right and accelerating. It all started after I replaced my front torque mount. I replaced my passenger cv axel, thinking it was the culprit. All my ball joints/ tie rod ends are all good. No play in any of them nor in the wheel bearing. I'm sure my rear motor mount is bad. But would this make a difference at the same rpms every time? I've done a little research and have a hunch that it might be the differential bearings in the transmission. Note: I do have play where the cv axel goes into the transmission. I had it before I replaced the cv and I still have it now. The axel is all the way in. I used a dead blow to make sure. Thanks ahead of time guys. This is my daily so I'm trying to diagnose it as soon as possible.
