November 2012: When I jacked my truck to investigate a gouge in the backside of the rotor, the tire flopped when it went up. Having just done ball joints, it was the bearing. This was the ONLY indication that the bearing was shot. No pulling to the left, no pulsations from the axle, no funky tire wear. So, with a quick trip to Circle K auto parts, $200 later, I have a Precision wheel hub assembly installed. YAYYYY!!!!
At 45 - 55 mph, there was a pulsation, and it got worse.....BOOOO!!!
Jan 2013: Removed "new" bearing and it was pushing grease out around 180* of the backside. Exchange it at Circle K auto parts and the new one pulsates in the same mph range. GRRRRR
Before I go back there and have a Donald Duck fit, what are OTHER items that could cause this? Like I said, the bad OEM bearing didn't pulsate. The axle seal was good, I installed the flat grey "washer" smooth side to the seal and I ensured the snap ring seated. This ISN'T rocket science, there has to be a simple reason for this.
Or do I just need to get my money back and buy one from Tousley Ford?
