Ask if the part I was looking at was correct for my truck Got asked to measure diff centre size Confirmed I had an 1150 rear axle Ordered bearing kit Kit arrived Bearings were too small Tried to contact the person I was dealing with and have had no response After talking with another sales person he informed me that the dually has larger bearings Now I have to order another bearing kit to be sent to Australia and wait another 2 weeks And I still haven’t spoke to anyone about the first bearing kit It seems no one is interested in discussing the wrong parts
