Could be a number of things. Does it get louder the faster you go? Is it more of a whine than a growl? Does the noise change on decel?

How was your backlash and pattern before and after?

thats what i think it is. i didnt have the tools to measure it. so i think its off. i didnt have any grease to check with either.

Thats something you should aways do because otherwise you have no idea where you start or end up. I am going to take a stab and now your backlash is different.

i beleive it is cause i only could put one shim in. and it wold only fit on the passenger side.

Yup, backlash is screwed...hopefully you didn't drive it far, but usually when you drive something that sounds that screwed for very long at all, you just ate a ring & pinion....

i drove it maybe a football field if that.

Hopefully it didn't damaged the hardened surface of the gears, once that happens, it won't be long for this world....

I have had a number of gm diffs loose the side bearings with about 1/32" play and been able to get a good setup pattern with no fears of anything failing. Then again I have also had a few that I had to replace the r/p.

Yeah, if the hardened surface wasn't damaged, should be ok---done the same myself...Hopefully your gears are ok shrtscrplr...if you see no visible damage, try and get the tools to properly set up the backlash...good luck and I hope you get it squared away!!!:awesomework:
