So the damn thing still makes alot of noise, slightly less since i changed to oil but still alot more than it should. I will be pulling the diff and splitting it to change bearings and seals hopefully the gears are ok...... $500+ for the gears... so its not to bad to do? what about setting "backlash"? i heard that not setting that properly could toast the diff. What about manuals? is there any decent service manual for an SS.
I guess this is a lesson i put 10,000 miles on the truck since original owner only changed tranny oil and engine oil, never assume that the person that owned it before changed transfer case or diff oil...... judging by the condition of the drain and fill plugs it has never been done in 84,000 miles........ (still paint on the bolts!)
