Just saw some pictures on ol' Le Reddit's /r/justrolledintotheshop. Grease was slung all around the inside of a wheel. The poster states, "Jeep Grand Cherokee recall, 'Some vehicles may not have had CV joint clamps installed in the factory.'"
I know we have had our fair share of recalls, with another one just rolled out for something that's already been recalled, but for the most part it's been shortcomings in design (and vehicle design, if you actually take a look at all the parts and shapes and contours, isn't simple anymore!) while this is just a plain old screw-up on the assembly line. Wow!
