Moaning noise from car....?

Something you can check. Raise the rear of the vehicle one side at a time with your jack and block it for safety reasons. Your emerg brake must be off as well. Grab the top of your tire and bottom of your tire and pull in and out to see if there is alot excess movement. Then try to spin it freely. Provided this is a front whl drive, make sure when you check this its on level ground and in gear. Hope this helps...
