Ours is a 2005 Jeep GC CRD auto with just over 70,000 miles on the speedo. Less than 2 months or 2000 miles ago we had a major service on the Jeep and in addition to the all the normal service the fluids in the front and rear axles were changed.
We did not use the Jeep much initially and then only on rural roads however recently we did a long tour with a caravan using motorways or freeways. Initially the car was quiet, but over distance and time we noticed that there appeared to be noise coming from the front which was getting louder the more we used the car.
Difficult to describe the noise, but at a low speed and when cornering slow it is like a pulsating drone and you can hear it pulsating and as speed increases the pulsating increases until it becomes one continuous annoying drone. I know diff whine which is normaly high pitched but this is a low pitch drone.
We are very concerned that maybe the incorrect or insufficient fluid was put into the diff or the correct additive was not used.
The noise only started after the servicing. I could be coincidence but we are very wary of service garages. Not sure if it could be a wheel bearing but as a mechanically noob it is a guess.
Any input would be welcome. Thanks.
