I hear a low frequency rumble when decelerating and at about 40 MPH. Sounds like the back pressure rumble when down shifting, but I don't think there is an exhaust leak. Sounds similar to when my sons car had bad wheel bearings.
Is there any way to tell if it is the front bearings and if it is the bearing how difficult a job is it to replace them?
Thanks in advance

Does it sound like it's coming from the front? The wheeel bearings usually make more noise in a turn one way or the other. If you raise it up, you may be ablr to turn things and find where the noise is coming from.
The front wheel bearings aren't to hard to do. Whatever it is and you want to do the job, get a Haynes or Chilton manual for reference. Your local library might have one.
I doesn't seem to be affected by turning. Just around 40 during acceleration and deceleration. although I don't know if after 40 it is unnoticeable because of increased frequency.
As far as replacement, I have heard that getting the bolts that hold the drive shaft into the hub can be a bear to get out and also that the bearing can be stuck to the shaft. if stuck to the shaft how do you get the bearings off the shaft?
Normally if wheel bearing is knackered , once it starts the droning noise it doesn't stop , especially at 40mph . Also , when driving ,noise should vary when moving wheel as load is transfered on and off bearing .
OK now the mystery deepens. I replace the wheel bearings and seals on both sides in the rear. The exercise was not in vain, the seals were pretty well worn to the point that only the rubber was exposed on the outside so they were gonna blow at any time.
Unfortunately I am still hearing the rumble between 40-30 mph and mostly during deceleration. I have a pretty aggressive tread on my tires. They are about 6mo old. Just rotated them when I did the brake job last week. Is it possible that it could be the tires? I do feel the tires when I am coming to a stop at low speeds ( < 10 mph ) I am thinking of finding another tire the same size as mine and using my spare and this other to see if the sound abates or lessens?
