We are running out of what to check.
My T/A have vibration. It occures only on coasting. In drive or in neutral. It Vibrate at really any speed over 20 or 30mph. It might be doing it at low speed too, but its definatelly more noticeble at higher speed.Its definately comming from floor. I think steering is shaking bit. But not sure if its coresponding with vibration on the car. At higher speed, it almost sound like small rock is hitting floorboard spraticaly.
I haven't check to see if driveshaft is out of balance. I really didn't think about it, as I thought if thats the case, it would vibrate no matter what i'm doing. Coasting or on gas.
Its shaking at the speed. Just vibration's frequency is not constant. i guess best way to discribe it is "tummbling". just not constant.
It all goes away as soon as I hit the gas.
Carrier(new carrier bearing, New Aubern LSD)
Bushing(trans, TQ arm, LCA)
None helped. What else can it possibly be????

Maybe you need to balance your driveshaft? My bro had to balance his on his 97

rear end maybe, check your tranny mounts and anything and everything to do with the driveshaft, it seems like it has to be related to your driveshaft

But funny thing is that backrash was perfect.
When i had the new carrier bearing installed along with new diffrential, ring and pinion was retained. So i have no idea whats that all about, as if it was new gear, would explain metal shaving
pinion gear is loose as well. when car is in air, and in Park, u can turn wheel alot as there is alot of play in it.
they are suggesting i should just get new rear end(used one i mean off of SS with shigher gear or something) as its much cheaper then trying to figure out what is going on with this rear end....
Its going back to shop that installed Aubern and carrier bearing 5 weeks ago next Monday, and they are going to figure out what they screwed up
