drivetrain vibration opinions
Well I have been chaseing down this problem for awhile.Heres my suspension mods I have adjustable tq arm adjustable panhard non-adjustable lower control arms and qa1 shocks with stock springs.My tq arm is adjusted to -2.The vibration I'm having is ever since I installed my 9inch this vibration happens on the decel.It vibrates the hell out of my center console.Know I'm thinking it my be my driveshaft not in the trans far enough.I noticed when I installed my rear the rear seats back further about a inch or so.Is there a possibility that I need adj lower control arms to move the rear forward and that would put the driveshaft further into the trans and that could solve my vibration.I also have a stock length spohn driveshaft and its a 6speed car.

Is the rear centered in the rear wheelwells? If it is to the rear, which a lot of them are from the factory by .5, then moving it forward by using adjustable lower control arms should certainly help out with your vibration. If the rear is centered, then the next step would indeed be a one inch longer driveshaft. Bob

You're welcome! I have seen a lot of stock 10 bolt cars with the rear towards the back. Normally it wouldn't be noticed unless a pair of larger 28" diameter tires are installed. Bob
