rear end making tons of noise after 4:10 install
 

I just had some 4:10s put into my 5.0 and there's tons of noise coming from the diff. There's use to be a slight whine from the 3:73s I had before but now with the 4:10s, there still a slight whine but tons of grinding noises...

The tech that did the work said he put in a new bearing. What else could it be...

Should I have gotten the whole rebuild kit.

That is not normal or good. Maybe the guy didnt shim it right for the new gears. I would have another shop listen to it and see what they think. If they say the other shop screwed up then I would see about having that shop fix it and send the original shop the bill. More than likely though they are going to make you take it back to who did the work and let them fix it. Good luck.

Yeah, I'm bringing the car back tonight for them to look at.

Thanks,

Tony
