For those of you wanting to eliminate the uneccessary turning of the front differential components on your WC/PW/M37 to prevent wear and increase gas mpg, these are an excellent value. They have no splines therefore will not turn the front axle. The only down side is that you will have to switch these with your splined flanges to go four wheeling, about a 10 min. You can't get a unit that will do this any cheaper unless you want to use excessed steel bean cans. Highly recommended!
