Solve Slip Yoke Noise
The problem with the Slip Yoke noise, It's the KIND of grease that you are using on the yoke splines. I've solved this problem for over 30 years. Use TEFLON grease, sold by FORD, I bought a small can of it about 30 years ago, don't know the part number, but it is teflon base and is light bluish white in color. Back then, it was about 25 bucks for a 8 or 12 oz can. I've only used this stuff for drive shaft slip yokes, as that was the reason I bought it for. I picked up a tip for using this stuff in a transmissions tips book in the 1970's.
