Reminds me of a farmer I use to help part time. He had a number of old farm tractors, and equipment. Could remember one day a u-joint broke on one of the older trucks....it was the one at the differential, yet the front one was nearly as bad. He ended up putting a couple used bearing caps hanging around on the existing battered u-joint, and called it fixed, good to go, instead of replacing both u-joints with new ones.Sorry, I agree with @tacojoel. Its likely played out suspension components.
Also why did you just replace one side? Does the other side have less miles on it? Generally, it is good practice to replace suspension components on Both sides SIMULTANEOUSLY.
FWIW, I just replaced the front wheel bearings on my '06. Easy task using front hub assemblies. The front hub assembly can not be installed backwards.
