[fastandlow03]

so i got a 03 silverado with what im guessing to be 373 rear gears haven't taken it apart part yet but it's clicking every time i turn. I just replaced my tranny 3rd gear went a month ago. about 2 years ago i decided to do a 4grand neutral drop i figured 4.8 V-8 that can't do a burn out well needless to say there went the first rear end. now this one is make that same horrible noise and no i didn't neutral drop . but i'm getting married next month, a little low on money, former body man got tools a garage and need to fix it if anyone has some great advise it would very much be appreciated.

junk yard G80 if you are broke. other wise a tru trac would be the wise decision. The are pretty straight forward install.

Well you will have to see what you broke 1st then go from there. Ron's machine on here has all you need for your rear end. (lol)
