Download this info. This is the problem,and how to repair it.The parts on page two should have been replaced the first time.What was the length of the warranty,it should have been covered the first time it was replaced.Read your warranty.Second, the parts and a new metal tag would have been put on the axle,to show the repair was preformed.,and a new 75W-140 gear oil should be used instead of 75W- 90.Plus a friction modifier.If the dealership did there home work,they should have repaired it right the first time.If I where you I would look at the rear axle to see if the metal tag is there.If the tag is not there then the same original parts where installed.Let me know if you have any questions.
I see you have been waiting some time online and you have not gotten a reply, So I will help. You are going to have one or both rear axle concerns. At speeds around 45-60 do you notice any whinning or howling on accel or coast. Do you feel a vibration binding sensation when accelerating from a stop turning pretty sharp?

The modifer is the problem. Modifer used to be made with whale fat, now that is illegal so it is made synthetic which does not hold up.
In 04 they dropped your complete rear axle assembly and installed a complete new one.
Will it occur again down the road? I cant say yes or no. I can say the vehicles which I replace the clutches in have not returned yet. I do not know about the ones which took my advice on a service attempted fix.
