Yep, Momo hub to the NRG QR which is in great working order. The connection at the QR is confirmed solid by putting vice grips on the steering shaft under the dash and measuring sweep as much as the steering wheel turns in degrees.
Its beyond the rubber insulator boot at the firewall where the shaft motion and rack output do not match. to the best of my knowledge there are 3 points of inspection:
-The u-joint in a rubber boot outside the firewall
-the clamp to splined pinion shaft of the rack
-lastly the mythical "pinion adjustment" in the rack that looks like a giant hex socket. Removal is described in the rack rebuild wiki in step 13 linked below.
