OMIX-ADA Fan Speed Control Knob Reviews
It would not go on with the metal retainer inside the knob. So I pulled out the metal retainer, slid the retainer over the shaft first, then pressed the knob on. Worked great. This was for my 1997 TJ.
There's a metal sleeve inside of this knob which made it impossible to slip on. Once that was removed it slid on (very tightly). My only gripe is the indicator line doesn't match to the fan speed circle. Other than that, it works just fine.
Very tight fit but works just fine.
