Default Re: U-joint special washer

Yes, you need it. It's actually a type of spring that has a specific type of name that I'd assume was name after the inventor. When you look, it's slightly concaved and this allows for some slight movement while still being substantial enough to hold the input shaft while also taking the force of the drive shaft wanting to push the U-joint forward and aft.
