Front Drive Shaft Becomes Too Short!

The front drive shaft on my 1996 Grand Cherokee Limited with 5.2L engine has done just that – became too short! 1 ˝” too short! No lifting, no collisions, no off-roading. This drive shaft is the type that has a CV joint on the front and double cardan joint on the rear. I discovered this while diagnosing a klunking noise coming from the driver’s floorpan area. The end of the drive shaft was just hanging loose in the rubber boot of the cv joint! I thought at first the cv joint wore out, but after installing a new one on the drive shaft and when I proceeded to reinstall the drive shaft, that’s when I discovered it was too short! The drive shaft appears to be adjustable, but the factory manual says once it has been installed it isn’t adjustable. I can’t understand how it became short as I have not been able to get it to adjust even after hours of soaking it with penetrating oils and even tried using heat. Anyone out there ever experienced this? Anyone have any idea of what could possibly cause this drive shaft to become too short?

that part that looks like it's for adjustment can't be freed up without destroying the plastic bushing that is used to lock it in place. don't know of any source for that.

it does sound like the cv just plain failed on you. i've seen a few people here complain that the new replacement joints aren't long enough and don't have enough slip in them.

Thanks for the comments Ratmonkey. I realize the best solution is to get a new drive shaft with double cardan joints on both ends but I don't want to put that kind of money into a car I plan to sell soon.

Ok, I dont have this specific issue. What I would like help on is are there any instructions on changing the CV boot? I snagged a DS off of a 4.0 witch I understand is longer then the one on my 5.9. I really just want to boot for now. Any help or links would be greatly appreciated. Thanks.

You don't just change the boot. If its torn. That joint is already on its way out.

Isn't the spline joint by the big nut the slip joint? I suspect that the shaft compressed and got stuck.

CV shaft does not have a slip joint. There is a collar in there that is fused from the the factory.
