03 cavy with 85k on odometer. New hubs left right, new struts, alignment, wheels rotated, trans fluid/filter changed. Horrible buzzing/growling noise from front end when driving 30mph and up. Sounds like a prop plan throttling up. Speeds up as car speed increases, but rpms have no effect. If car is put in neutral at highway speed, has no effect on noise. Braking has no effect but to slow noise speed down with vehicle speed. Coasting has no effect. Front end is tight, no slop in anything, no popping, no clunking. I am at a loss.
Aparently this is not an uncommon problem with third gen. cavaliers. As far as the temp being higher on driver side rotor, remember that is the side with the transmission, that side, as weird as it sounds is working harder than the other side because of engine drag and power being applied to that wheel. Does it sound like it could be air blowing through a part of the car vibrating something loudly? Im at a loss also, sorry didnt help much. I'll repost if I find anything for you.

when you rotate the tires and their is no change check the c/v axle -and hub 25k is not considered new have changed hubs that have gone bad at 10k -look into ball joints,upper lower bushings ,tie rod,struts the latter can cause vibration but usually at all speeds
ok does noise change when turning left or right if not its not a wheel bearing next try putting in neutral at 55 does noise change what you are looking for these is pinion and carrier bearings in differential the noise can be coming from several places have you checked all your fluid levels front and rear diffs and transfer case also check fluid condition also check for metal in fluids if you stick finger or paper towel in and if you see metal you will know where your noise is coming from
i have been fooled by this one way to many times. when a wheel bearing or hub assesembly is making noise, it will sound like it is comming from the other side. i do not know why this is. but one test will prove if and which one. when growling noise occurs, notice, when turning left or right, does noise get louder and quieter as you turn? if so then it is wheel bearing. when turning left the right side will make more noise. when turning right the left side will make more noise. if always the same then, tires or transmission need addressing. the cv axle does not make a growling noise, unless front wheel drive car does not move, it makes a clicking or poping noise. sorry but at least you dont have to replace other axle
If you put on new struts the bottom bolt hole is oblong for camber adjustments.Where the old struts bottom hole was not. If you put a jack under the lower control arm, jack the wheel off the ground and adjust the struts camber to where the wheel looks straight.And tighten bolts.
Wheel Hub Assemblies: Systems and Diagnosis of Worn Hub Assemblies & Bearings
Front wheel hub assemblies and bearings control the position of, and reduce the resistance of, vehicle wheels in contact with the pavement. When they fail, front wheels may not be kept in position and vibration and noise usually develop. Symptoms that normally develop as a result of these worn parts include:
A humming, rumbling or growling noise which increases with acceleration or as the vehicles turns
Vibration felt in the steering wheel, which changes with vehicle speed or as the vehicle turns
Looseness or excessive play in the steering wheel (especially while driving over rough road surfaces)
A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)
Pulling to one side when braking.
Roughness - with the vehicle of the ground, roughness or vibration when rotating the wheel
Looseness - with the vehicle off the ground, looseness when wiggling the wheel back and forth (Looseness may also indicate a worn ball joint)
Excessive brake pedal play can also indicate sloppy or excessively loose wheel bearings
ABS failure in the system may be related to failure of the ABS sensor in the hub assembly or the internal sensor in the wheel bearing
