Whining sound from under neath car.sound begins at 40 mph,whining continues to get louder going faster doesn't matter coasting or in nuetral(automatic transmission)as long as it's not below 35. I'm thinking it's a bearing but at the differential on 2007 2.2L. Upon jacking up tires,no play in tires,both Tires does not spin freely.Both tires are worn too. Also when I rotate back and forth both tires in 9 and 3 oclock position I hear a clicking sound where the axle spindle meets the differential.This happens at both sides .The boots look great. What kind of a repair job is this and is there a online manual that has diagrams and how to repair?
