whenever i take off from a stop sign/ light a little hard i get a squeek and feel a clunk. at first i thought it was my u-joints but i replaced those and its still there, and now im leaning towards the rearend...anybody got this or know what it is?

 

Mine does it too.. Have yet to find a answere for mine yet.. it's a 2000 silverado. There are some other forums on here where people are discussing the same problem.. I have heard everything from rearend wrap up to transfer case chain slap.. Only words of hope I can give you is that mine has been doing it for the last 25,000 miles .. I am leaning towrad transfer case... Good Luck
