Is it from a dealer or the land of almost right? Coat both inside and outside threads with blue lock locktite. Screw knob on as far as you can. Drape a rag over the knob and use a pair of Channelocks to tighten another half turn. Let sit for 24 hours.

Best to take the steering wheel off and remove the lever assembly, then you can put vise grips on the opposite end and tighten the knob.
