This is a heavy duty, non-greasable replacement u-joint for the front axles of your 2000-2002 Ram HD. Wait....did we say NON-greasable? Yes, we sure did! With a properly sealed u-joint, you truly do not need the ability to service your u-joints, in fact, its merely a weak point in the u-joint because of the grease channels as they are literally hollow tubes that are the weakest point of the joint. These joints from Spicer feature Perma-lube improved seals for a long service life without the need of crawling under the front end of your truck with a grease gun.
