More vibration issues.....

I'd wager on it being in the trans. Maybe the output shaft had a bad bearing? Anybody around with a Tbird you could borrow the d/s from to rule it out?


If the tires/wheels check out, I feel that it's in the tranny...

Tires were balanced yesterday....no change.I know nothing of the T-5.I wonder how hard it would be to replace that bearing.

It can't be the tranny-it was doing the same thing with the aod. Look I'll come pick the car up and bring it back to you at the end of the summer-that should be enough time for me to diagnose your problem.:D

LOL.....but NO !!! Thanks though.LOL  I'm wondering if it's maybe the bearings in the differential.How hard are those to change? The axle bearings I've done,the carrier,I haven't done.

But youve changed the rear 3 times- bearings would make noise all the time. I'm stumped bro.

Swapped the rear completely out of the car for another one, you say?

How about the axle shafts....did you reuse those, or different ones.

(a little process of elimination here lol)

How about brake drums or rotors on the rear (front too..), are they anything new, or have they been on the car for some time?

Something rotational is causing...don't rule out something in the front.

Thanks Kitz.I'm going to focus on the driveshaft first,then i'll go from there.

I swapped the axle shafts and still a vibration.I also picked up a Crown Vic aluminum shaft today.Now to find somewhere to shorten and balance it.

It would be cheaper for me to do it.I'm going to call around in Durant Ok. (about an hour away) and see if they have a driveshaft place.

are you sure it will slip into the back of your T5? if it came out of a 4r70w, chances are it has the larger yoke and u-joints. meaning your stock t-bird yoke won't work.

The driveshaft came from an AOD car.

Oh,the Crown Vic drive shaft.....I'm sure they are different,but,they have adapter u-joints for such a swap.We did the same thing putting an Explorer driveshaft with the same rear and tranny combo.

The machine shop you know should be able to balance that.

I'll check into the angle. As far as driveline shops,we have one,but they can straighten a driveshaft,but nor balance....so,what good is that?


I have adjustable CHE upper control arms and have adjusted the pinion angle perfectly and still have the vibration (although it helped).  The way it sounds, I think we are having the same issue...

I also totally rebuilt the 8.8 after I swapped it in because of this vibration.  I installed a new carrier and all new bearings and still vibrates.  I am leaning towards 1.) driveshaft 2.) bent axle
