I have a 2008 Dodge Charger, almost 125k miles on it. I've noticed in the last month or so that when I accelerate, usually between 60-75mph, my car feels like it's dragging and shaking. My whole car vibrates and feels like it doesn't want to go. It stops once I get up to speed, typically. It also feels like it's occurring on the passenger side, rear.

I've also noticed it does this same thing sometimes when I'm backing up. Sounds like a bad grinding sound.

I had my tie rods replaced and an alignment done, my back brake pads have been replaced and I just bought a whole set of tires. I thought this would solve the problem, but it hasn't.

I also took it to Auto Zone to have them run diagnostics and it showed nothing.

Any ideas?

 

Did you check your rear suspension or axle?

 

Yes, I had it completely aligned and inspected. We believe it may be the carrier bearing for the driveshaft

 

Diagnostics, eh? Ok.






Those rear differentials require attention like any other maintenance. The axle seal may have lost all your fluid.
