The left one needs to be "tighter" (more CW) to get it level. Should I have anything checked out before welding in torque boxes/subframe connetors? The car does ride and drive pretty well. Thanks, John

Did you know that one bar will carry the front end? Although you would have to take one wheel off to accomplish this.

I had to redo my roadrunner bacause of the same problem.. one tight bar will hold up the entire front end. They should be adjusted pretty even side to side.. Two or three turns maybe but 10 is wrong.. Video Little Red Wagon Indy Nats,BurnoutContest

Thanks, John there's a few possible reasons for this. 1. Torsion bars have different rates- either mis matched pair or one is just weaker 2. One hex in the trans crossmember was welded in slighted different clocking than the other 3. Rear springs are mismatched rates. The torsion bars can be adjusted to level a car with one weak rear spring. 4. Car unibody is twisted. This would be obvious though, usually with a very wide fender to door gap at the rocker. Overall not unusual really.
