If you don't put the bolt in the wheel or don't tighten it per spec it will come loose. The wheel is soft aluminum the shaft is steel. After a few weeks driving you will notice a "clicking" sound in the steering. That is the wheel getting a little sloppy. After a few more weeks it will feel downright loose. Not knowing what this strange sound and feel is you will overthink the problem and require additional support and eventually stop by RacingRobs house for a beer and ask him his valued opinion.Originally posted by Aaron SIlidker:
Even without a bolt the steering wheel will not come off, the hub is pressed onto the shaft.
