What do you folks feel is the best way to center your rearend laterally, or side to side? Just because the drive shaft looks straight, isnt good enough for me. How do you guys do it?

On our DW cars they give us a measuremtn from the outside of the frame rail to go by. I will use that to get close but try to keep my left side tires lined up and the RR sucked in a little bit.

if your chassis does not have a set way to do it, like a dw. then i would put my left side in line both wheels, and then have the rr about 2-3 inches or whatever it is 4 inside of the rf.
but i would put my left side in line.

I take a measurement from the front of the drive shaft to a frame tube that runs parallel to the engine/trans centerline.
Then I use this measurement and duplicate it at the rear of the driveshaft. This tells me the shaft is perpendicular to the engine/trans centerline.

Keeping the driveshaft straight in the car isn't that big of a deal. I move the rearend left and right depending on what I want the car to do. And if you think about it the driveshaft never stays straight in the car. It is always moving left to right dependent upon your panhard geometry.

I agree with all of these replys. The main thing i think is making sure both swing arms are angled in the same.

Get you an angle finder and check them. Best way. But as previously posted not a critical issue other than knowing that you have a baseline and what parameters you can adjust with.

I made a tool to center my rear end. I know the manufacturer's measurement to the right frame rail from the bottom center bolt on the 9". I took a washer, to fit over that bolt, and welded on a rod, which I then cut to the exact length. Works great.
