djeady, Don't ya' mean Not difficult Nor expensive to fix, Normally.
usmc13, Usually one just needs to remove the front wheel. Remove the drive unit from the wheel, it just pulls off. There is a winged tab attached to a ring gear, it will usually fall out of the drive unit if held vertical. One just needs to Re-Flatten the tabs so they will engage the slots in the wheel hub.
Re-grease the ring gear teeth and center bearing area.
DO NOT wash out the old grease in the drive unit. Because one can NOT re-grease the pinion shaft, which is Pinned into place. If the pinion seizes, it locks the ring gear, which holds the winged tab washer, which will shear the aluminum drive flange off of the wheel hub.
It is possible that this has already happened and then it does get expensive. (Replacement wheel assy and speedo drive unit.)
Modify at "YOUR OWN RISK"!
