This looks like quality stock and we rely on the Timkin name. Time will tell how durable it is and review the rating and (hopefully) adjust it up or down. Pulling off the old bearings wasn't fun but they come out of the mini skids with enough rattle which is a must here in the rust belt as you can see in the photo. Unfortunately this is the second bearing on the pass. The front and the driver's front were also replaced twice. All this at 110,000 per Odo, so I seem to be getting around 45,000 for Motorcraft stock. Enjoy a longer lifespan with the Timken update 15 months: no problems and smooth operation.
