i just had both of my axles replaced. it took them a week, but its a good friend so no biggie. anyway, i had my max back for 2 days and it makes a low groaning/rumbling noise. i have brand new tires so i know its not them. anyway, if someone has any light to shed on this situation it would be greatly appreciated.

One of my axles I had the boots rebuilt. It doesnt make noise like it did before, but I suspect the shop didnt rebuild the joint b/c when turning right, you can feel slight grinding in the axle. When I turn left, there is nothing.
