Took the ol" TBSS into get an alignment and of course come back to pick it up and find the alignment wasn"t done because the driver"s side wheel hub needed to be replaced. I politely declined the $500 replacement estimate and did a little research on which hub to purchase. Many have stated the cheaper replacement hubs don"t last more than a year most of the times. Moog and Timken were mentioned as a good replacement. I purchased a Timken replacement (part # 513188). Total time to install was a little over an hour which included taking a few pictures and writing down a few notes. Fairly easy and straightforward installation.

It was really a pretty simple install. With all the tools lined out, I don"t see why someone couldn"t have this done in 45 mins.
