I was helping my son change the u joints in his 06 Ram. I beat up the part that bolts to the pinion. I went to our local Ram dealer and they wanted $200 for it. It had a Spicer number on it. There happened to be a mechanic at the counter. He told me to take it to a Spicer dealer and ask them. That was very good advice. They had it in stock for $40. They sold me 2 Spicer u joints and put the whole thing together for $125 out the door.
