I thought about just up and replacing them as well. Didn't want to spend 200 dollars or so on both sets of wheel bearings that I really didn't need. The bearings on there were in good condition. Just needed to be re-greased I believe. It fixed the noise coming from the back so Id assume that the bearings are in good shape. But if it comes back or they break, Ill just replace them then. I will admit it was a lot of work and a lot of mess for all of that. But thats ok with me. Thanks for the input.
