Question about 2001 Ford Windstar
I took some of the front but the front end off thinking it was a cv joint. But the shaft that goes into trans had alot of slack in it. prob abot 1/8". I hope I am terribly wrong. but any ideas?
Well it could be a worn tire, but if the axle can slide back and forth, it could be a worn hub bearing. Usually when the hub bearing goes it makes more noise when you take an opposite turn. Turning puts extra load on the opposite side of the turn.
The axle has splines to slide into the transmission and into the hub.

SOURCE: CV joint questions
A c/v joint is pretty much just a better universal joint in that it permits more flex range than a simple cross. (like a driveshaft universal) If it were possible to make a universal with eight caps instead of four, it would have similar range but would be impossible to install.
Few suv's used in street applications have a true locking front differential as that makes steering very difficult on turns (outer wheel needs to turn faster than one on inside of turn as the outside "circle" is larger.) Most suv's have an "open" differential that permits easy turning. In reality most 4x4's only have two wheels driving the vehicle at any one time. Most optional setups have a positraction diff ( also known as a limited slip as it allows for slippage so wheels can change speed on turns)at the rear giving you a total of three wheels pushing. Off-road guys will often install a posi at the front, or a more radical approach is a "spool" that is 100% locked all the time, making street driving nearly impossible. Your front differential is "locked" or actually connected to the drivetrain by way of a transfer case that does exactly that...It transfers power to the differentials. On some it does this automatically by way of a viscous coupler inside the unit, or others that are engaged by the driver by either an electric servo or a direct lever.
How far you turn the front wheels determines how much stress you are putting on the c/v joint. Most vehicles have a "stop" bolt somewhere on the suspension that stops the front end from turning further than it should. Most times the steering pump will begin to whine as you near the limit.
C/v joints should last a very long time. Generally they fail because though they are internally designed very well, they are protected by a simple rubber boot. Once that boot is torn, split or otherwise compromised, road dirt enters and quickly destroys the joint.
Once you find a split boot you can almost bet that the joint is in one stage or another of failure. The price of the boot is often about one third the price of a complete joint or even a replacement axle with joints installed. therefore changing just the boot is foolish.
Symptoms of a bad joint are clicking binding or vibration from the area of the joint, but, sometimes vibration can be caused by wheel balance or a failed hub bearing. Making good diagnosis important.

Yes is the short answer. Did you blow the gears in your front differential or you going to put a whole new pumpkin in? If you are replacing the entire pumpkin drain it first. Then make sure to support it with a transmission jack first. Remove the tires. Then remover the CV axles and lower the pumpkin. Your vehicle requires a 75w90 synthetic axle lube for a refill. Good luck.
