About a month ago I replaced the driver side hub with another brand. It broke during installation and I ordered the original mounting sleeve but the panel did not fit on the passenger side. So I decided to order this set and I was very impressed with the quality and finish of these hubs. The design of the finger rests is very nice (I can literally rotate them with one finger). The bearings turn perfectly. There is no plastic cage like the OEM part and other brands I've tried. In fact, there is no plastic. The kit includes grease, anti-seize and new screws. The warranty lasts for the lifetime of your truck (provided you were the original purchaser of the hubs). I wish I wasn't such a curmudgeon and wasted money on it.
