[8swbk10]

yup theyre 10 bolts with 3.08 gears. it only makes the noise when i let off the the gas and then if i push in the clutch it goes away so thats what had me thinking it might be something in the tranny or tcase. but i still need to check the rear and front diffs out anyway. 2 nights ago was the first time the truck was driven on the road since like 2001 so im just finding more things out now. the last thing i wanna do is pull the engine and tranny again and if its the rears my friend has a set of 8lugs with 4.10 gears that ill pick up. thanks for the answers ill check out the rears tommarow when i do the brakes
