Steering wheel off center after box replacement

Seems weird, because I was under the impression that there was only one way the column adapter could go on the worm gear shaft on these, though I don't know anything about how Steer and Gear and what shafts they use. Typically there is a raised portion of the worm gear in the center where the pitch is a little tighter, you would think that would still need to be in the center, so maybe Steer&Gear worm shafts don't have the master tooth and allow you to put the pot connector on in any position.

Quick question,.... when your tires are centered and straight ahead, are you sure you are in the center of your gearbox travel. In other words, start with the tires pointing straight forward and turn the wheel to full lock in both directions and see if the amount of turns is the same. I'm thinking that maybe Steer & Gear shafts don't have the master key and can be put on anywhere and they didn't have it centered when you installed it.

If there is no master tooth on the splined worm gear shaft, you can just pop the coupler off, center the wheel, and put it back on. I would still find center of the gear box travel though and make sure your tires are straight forward when the gearbox is centered. Obviously when the gearbox is at center position and steering wheel is centered, your tires should be pointing straight forward. If not, you will have to adjust each tie rod adjuster equally to bring them back to center, then off to alignment shop for final adjustment. I don't know any other way to center up the steering wheel on these cars.

Hope that helps
