Default bent driveshaft?

recently, it seems like a pretty decent "shake" has struck the rear of my car

at around 40-45 mph, the back of the car will start to "bounce" more or less, causing the hatch to rattle and even make the shifter jump up and down pretty noticeably

does this sound like a bent driveshaft? the car also has a double adj. panhard bar, lca's/reloc. brackets, bmr springs and adj. drag shocks

any input is appreciated!

Wouldn't a tire problem be something noticeable in a speed range while a drive shaft issue would happen at a certain RPM? If the drive shaft was bent I'm sure it would vibrate worse and worse the higher rpm's you pull.

If you still have the factory torque arm, take a look at it to make sure it isn't bending on you. I have seen the oem torque arms bend approx six inches ahead of the rear, and will cause the front of the rear to angle up. This will cause a lot of vibration from the u-joints. Bob
