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?
