[66AC]

This happened once on my ERA six pin front with knockoffs. Doug at ERA suggested putting the spinner on loose, and turning the steering wheel left to right and back again while the car was stationary and on the ground. The left and right torque on the tire and wheel will pop it loose. Also I sprayed the inside of the hub and wheel with a product called KROIL, which is like PB Blaster but this stuff really seems to creep well. Well after about 5 or 6 left and rights, the wheel came loose. Your mileage may vary. Hope this helps.
