When aligning a rear axle so it's perpendicular with the car, what is generally accepted as the maximum amount of thrust? Would being within 1/8" from side to side at the ends of the axle be acceptable?

AKA known as centerline thrust.
1/8 should be WAY fine, and they were much farther off than that right out of the box.
Personally I try to pay more attention to weather the car tracks straight, instead of looking like it's going down the road sideways.
That's sort of what I was thinking. How much does it need to be off for it to look like it's tracking sideways? I have no frame of reference. Thanks again.
RRR is right. I made mine perfect w/ an 1/8" shim, can`t tell the diff.!Thrust angle is a comparison of the angles of the center line of the axle to the center line of the vehicle, from front to rear, so the sides of the axle really have nothing to do with it. 1/8" is plenty acceptable for a street car, but of course, like everything else, if you are building a race only badass, you want it as perfect as possible.
Like Greg said though, a LOT of cars are riding around with way more thrust angle than 1//8".
Kimmer,someone did it right...Put it on a 4 wheel alignment machine and it will tell u where it is at and if it is acceptable. I had a d60 shortened and welded ends on it and the thrust angle is 0,when checked on the alignment machine. Kim
