Jim is right on the money....pack the space between the coils on the spring full of grease....and raise/pump it up and down till it quiets...about 7/8 of the way up so you do not have to give it that initial tug every time.
Thanks I'll have to give it a try next Wednesday....dumb question, but what type of grease ? Will the stuff to grease ball joints in my grease gun work fine ?
