Because the steering wheel had about 1/4 turn play and everything else is tight, we took the steering box apart and found some sideways play of the rollers as well as play between the rollers and the worm gear. Is there supposed to be some play or should we aim for tightening as much as possible? So far, we have tightened the rollers and took out two of the thick shims of the sector shaft. The latter removed the play between the rollers and worm gear. Right now, we don't have a means to measure whether the rollers are centered, any suggestions? Also, does someone know what the pre-load on the sector shaft should be? Thanks in advance, Claudia
