Ok I need some help...

I have a 64 Impala I put hydros in. I'm using the stock rear end, stock upper and lower rear control arms (reinforced not lengthen), stock pan hard bar.

I put a TH350 transmission in it. But I had to cut the front section of the driveshaft to fit 'cause the transmission tail is longer than the powerglide.

So the front section of the driveshaft is cut and balanced b4 the center bearing. The second half of the drive shaft which is from the center bearing to the rear diff is stock.

Now I hit the switch for the fist time in this car since all this work has been done and the driver rear wheel moves forward closer to the front of the car than thee passenger side is this normal?

AND I ripped the center bearing out from its location....Actual the rear driveshaft pushed forward and the center bearing support ripped out from the frame...If I used a heavy duty center bearing would that help?

To my understanding the center bearing is bolted to the frame and it’s not supposed to move. Now because the rear piece driveshaft is stock...this shouldn't happen?


What could be the problem here?

:thumbsup: :thumbsup: :thumbsup: :thumbsup:

when the rear lifts there is fast motion on the driveshaft from hydro's. The drive shaft gets pulled from the rear since its moving unlike the front section attached to the stationary transmission.. The rear needs a slip joint to allow the motion from the pull. The reason the rear moved is because of the stress on the all metal carrier. On the old rubber carrier the rubber would give way and pull the bearing out of the rubber and slap around. If there is no rubber to give then the driveshaft will pull on the rear axle and movement will give way to your bushings on your trailer arms for your axle. It is a simple fix and most driveline shops can do it or contact Big Rich on here. Don't get stressed, its an easy fix for around a couple hundered. :cool:

And. Notch the bottom of the tunnel out
:yes: :yes:

Without notching, you will still have problems, even with a slip yoke. The axle moving side-side is not a huge problem, just be careful raising the ass while driving. The stock setup on the Impalas causes this. Wishbone would fix it if you are concerned.

The telescoping part of the shaft is the rear shaft.

In this picture, the front is to the left, rear to the right. In the middle, from left to right, you can see the center bearing, U-joint and telescoping section.
