How many of the 4 holes inside the hub should have the small springs?
You need the rotation for the breakout, you can have the same issue with the wrong grease in cold weather.

What brands of grease did you try?
I have used Exxon-Mobile SCH-100 (Airframe's preferred lube-synthetic), Aeroshell 22-synthetic, and Lubriplate Low Temp-mineral. Mechanics often use Aeroshell 5-mineral or 7-synthetic year round in the shop in my experience. The problem is grease shouldn't be mixed (mineral versus synthetic base oil for example) as it can cause separation of the thickener and lube bases and other issues. So can sitting under pressure in the grease gun or load in the tailwheel.
Pick one and stick with it.
