ok so typical vibration at 63ish to about 80 almost violent at times and gets worse under light braking, then under heavy braking it vanishes. mostly feel it in the seat and not so much the wheel. new rotors and pads all around, ill check the wheel balance tomorrow but it doesnt feel like that, just put a new guibo in the rear shaft and with the car on a lift at 60 theres no noticeable movement besides the passenger rear axle moving slightly. u joint seems to be ok but not ruled out yet. my next suspect is rtabs and or subframe mounts. anyone else have any other ideas?

Is it wheel speed or driveshaft speed? -
Feels like shaft speed but when I pulled the old guibo and found that it was well cracked I would have thought that it would at least change with the new guibo but not at all and I can't feel it at all in the shifter (I understand they aren't directly connected but thought I'd feel it at least a little )Comment

left rear wheel 20gm out of balance still small vibration, guessing its the imbalance in the rest of the wheels. guess it just goes to show how a wheel unbalance can manifest itself into a vibrationComment
