Question Please Help!! Cracked Trans Housing AGAIN!

In the short I was hit and had the rear and ds replaced, there was vibration issue when returned to me and noticed the trans was cracked. Ins replaced trans got DS balanced and trans cracked again. I dont have a clue what could be doing this so any help would be great. BTW, the initial detailed post with pics is in the Trans Section: Inital Thread Here

Is it possible that the frame was warped enough that the rear end is too close to the tranny now, which makes the drive shaft too long? If the shaft is too long, bumps in the road could be causing it to bottom out on the slip joint, which would transfer a lot of energy to the tranny. If that is the case, you should be hearing a fairly audible bang when you hit bumps.

What I think happened was while the DS was 135oz out of balanace the shop that was doing the DS test drove it to fast and the DS vibration popped the trans.

What about damage up front?

Those are some nasty cracks, similar to mine caused by a breaking rear driveshaft. Obviously not the case for you. But what about motor/tranny mounts? A good hit can throw everything off kilter, and if you got hit that hard there's a chance it moved things around towards the front too since its all connected.

Keep spending the insurance companies money until they write it off and buy you a new one.

man that sucks

I don't think any DS should take a ""bunch of weight"" for 1

usually a 3/8's washer is all mine ever get ..

I also would look into the theory of 1 of the DS being a wrong length and jacking the transmission around upon compression.

and verify the cross member and support is holding the weight properly since that is a lot of leverage hanging off of the bell housing

good luck .. keep us posted
