Rear Vibration - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 2002 Corolla. The rear end starts to shake my teeth out at around 55mpg and continues until I reach 70/75mph; it gets worst the faster I accelerate.
I have:
Replaced the tires
Rotated the rims/tires
Replaced/swooped out/borrowed the tires/rims from a 2001 corolla (sisters car)
Check the rear bearings (seem good no play, spins free)
Replaced the rear struts.
Check the rear bushings (seem ok)

Any advice would be welcomed

Thanks

Ya finally got it fixed

In the process this problem forced me to replace 4 extremely bad (not working any longer) struts/shocks.

I Thoroughly check out my bushings (look good so far)

I ended up doing a full service, in short: tranny, plugs, coolant, stat, hoses, belt among other things.

i hate trying to find the source of vibration issues almost as bad as finding water leaks

Anyway here are the pics to the right side axel replacement.

Once i had the axel out i found the joint had worn. i am doing an educated guess but i believe due to the worn joint the axel was out of balance causing the car to shake.
once i took the car for a test drive i found that all the shaking in the steering wheel went away .

Here are the pics

have you checked the front ball joints? or the tie rod ends? are you 100% sure that its coming from the rear? does the steering wheel shake when the vibration occurs? if so it is more than likely in the front end.

Milky thanks for the input, the vibration is/seems in the set, the steering wheel is not shacking.
At this point i am open to just about anything. i have started to think i need to look at the front end a lot closer i.e. bearings, struts, bushings, CV joint, or i pay a real mechanic to locate the problem.

Can the rear end suspension be aligned in the corolla/prizm?

yes. in fact during an alignment it is common to start with the rear first if it is out of spec. this is because the rear alignment spec (in or out) has a direct effect on the front end alignment and a bigger impact on how the car will drive. if the rear end is not trailing perfectly or close to it, behind the front end, then you can create a serious problem depending on how bad it is. the worst being a car that is unstable in the straights and corners. having too much under-steer (resistance to turn / pushes the front end) or having too much over-steer (wants to keep turning / rear end swinging out) can be dangerous even with experienced drivers.
