Can someone suggest what I should do about this. I took it to dealer when it was in warranty and got this fixed and now it's shuddering again. Where is a good type of place to get this fixed? No more warranty. Should I get a different design?
+3 on the Eaton. I have an Eaton TrueTrac installed in my 2008 Screw and it is great! Silent, smooth, and imperceptible when it locks up. No clutch packs to change, in fact, no maintainance at all. I'm going to install one in the front diff soon.
When I started having problems with the clutch pack on my truck it was after they had replaced some bearings in the rear-end (could be coincidence?). I was 600 miles from home when the clutches started to act up.
I took my truck to the local Ford dealer where I was, the mechanic checked it out and told me it was the clutch pack, when he found out I had just had the bearings replaced he suggested adding some additional (I don't remember what he called it) conditioner required for this rear-end. I felt he was looking out for my pocket and I appreciated it.
He said if too little of the conditioner was added it could cause this to happen and he had seen the problem go away when the proper amount was added. When I told him it was still under warranty, he said he would replace the pack.
When I picked up my truck, he told me according to the warranty repair sheet when the bearings were replaced they had not added the proper amount.
If you can, check to see how much of this conditioner was added at the last repair, how much should have been added and if you can add any more. It might work and save you some $$$.
If you allowed the rear-end to be serviced by one of the quick oil change shops, you probably don't have any in it.
Sorry for so long of a post. For what it is worth Graham Ford in Mansfield, Ohio was the dealer and they were great.
If the rear is an 8.8 you can buy the clutch pack from Summit for about $50 and they take about half an hour to change if the preload spring doesn't screw you to badly. If it's a 9.75, it is worth your money to have someone do it. The Eaton is a great upgrade, but once I put the clutches in mine the right way (Ford does it wierd) it has given me no further trouble.

Confuscious say "Man who have no use for jackstand have promising career as jackstand".
I had my clutch pack, bearings, ring and pinion replaced under warranty at 35K. I now have 74K and the only problem I have is when I let off and give it gas it gives a jolt when they lock up. I have the 9.75. Is there a replacment TrueTrac for this or is it the Eaton limited slip? Also, does Eaton make a ring and pinion set for the 9.75?
Eaton makes both a True Trac and a limited slip for the 9.75. I feel the True Trac, though a bit more expensive, is a much better alternative. There are no clutch packs in the True Trac. It is a gear drive affair which is silent and seamless. I have one in my rear diff and will soon be putting one in the front.
