Last year my front drive shaft started squealing. After a frustrating time trying to get it fixed by the dealership under warranty, I eventually pulled the drive shaft and replaced the u-joints and centering ball myself. As you can tell from the pictures taken shortly after my last trip to the dealership, they were rather destroyed.. It’s actually a pretty simple process, and a cheap u-joint tool from Princes Auto helped a lot… If only getting a dealership to do a proper warranty repair was this easy….
So, if you hear the angry sparrows a calling from your drive shaft, and lubricating does not help, replace those u-joints!
