Diff problem.

Well I took my diff down to the diff specialist and said that i put a feeler guage between pinion and crown and it came to 15 on the feeler guage. He said that 12 is usually what it is, then reconmended i look at the wheel bearings.

So whilst i have the diff out, i had put another one in and got the same noise, i think i will rebuild the back axle assembley all in one hit. Will change the front bearings and check out the diff. fix the oil leaks, and uni joints all in a hit.
