Re: E4OD worsening problems
The U-joints for your drive shaft are not that expensive. Not more than $45 for all three. And believe me, if you are going to replace one, you might as well do them all at the same time. If your vehicle has seen a lot of wear, then you will need a press or big vise and appropriate sized sockets to press the U-joints out. Then can be a little of a pain. It just takes about an hour at the most to get the job done.
Because if one U-joint went bad, then the others took the abuse, too.
