Tranny serviced, oil and filter by GM dealer recently (20k). Transfer case oil changed at same time.
Noise is not nioticeable in 4x4 operation.
New u-joints last year (and regreased this spring)
Tranny mount checked and solid.
I did change rear diff oil and add GM addative, and 50% of niose is gone. Rear end was good, took back off, no metal filings, clean and new gasket added. Changed front diff oil at same time.
Added GM replacement kit rubbers to the leaf springs (kit) and noise is gone. GM said these sometimes when worn permit 'slip' in the springs and that is the noise. Been only two days now driving, noise is 99% gone, just normal from what I can tell.
Anyone else every have a similar experience?
