Replaced ball joints, and axel joints

[87fleetsidedude]

What should I expect my truck to do after These get replaced? should i smell anything. or hear anything? I just got my truck from the shop and i can hear a quiet grinding noise, i can't really tell if it is my axel, or my tires on the pavement, my tires are darn near bald and aren't in good condition so i'm thinking they are the cause of the noise. also when i brake at 55 my truck shakes a little bit, could that be a warped rotor, or out of balance tires?

Thanks for making it through my post haha.
