Default Setting Pinion Angle on a slanted driveway

I am installing my adjustable torque arm today. I have the angle tool and a decent understanding on how to use it (thanks BMR).
Unfortunately, I do not have access to a lift, nor do I have a second person with me.
The info I have read says to have the vehicle resting on all 4 wheels and level, but I don't have that capability. If I raised the vehicle by the pumpkin so the wheels were level with each other, would this be sufficient?
Any other ideas are certainly welcome.

You have a jack, now go get some 2"x8" lumber and some wood shims.

Start off by chopping the 2"x8" into 2' long chunks and get the car up on at least 2 peices per wheel, this will allow you to crawl under the car (barely).

Now start adding wood under the back wheels until they are close to being level with the front, use the shims to make the final adjustments... do this on all four wheels if needed, it's important to get the car leveled out (front to back and side to side).

Now chop a few small 4" long peices off a fresh 2x8 and nail (or screw) them down in front and behind, each front tire... keeps the car in place and holds the shims in the proper location, do the same with the rear tires.

*Shims should be wedged under the top 2x8, the one directly under the tire.*

Adjust your suspension, per normal instructions.

Hope this helps.

Pull that bitch into the street and jack her up if you can.

I live in a neighborhood so my neighbors didn't mind much.

I used to do that, but then she divorced me. But you're right, the neighbors enjoyed the show while it lasted.
Thanks for the ideas, guys. It's a bitch doing this kind of stuff in your driveway.

if u are setting the car up 4 the street
take the angle of your drive shaft and then put the rear end 1/2-1 deg. more angled down

You raise a valid point. It is an A4, stock ride height, for the street. The articles I have read claim -2 degrees for autos. Could this be misinformation?

You make a valid point. IIRC, the pinion angle compares the driveshaft angle to the rear angle. No need to make it more difficult than it is.
Thanks.
