Whinning sound underneath the truck?
There is a sound like gears disengaging at a speed of 50-60 km. If I continue driving at the same speed, the sound does not go away. I have to slow down and at the speed between 10-20 km I hear a tug like sound. And the truck jerks forward. Any suggestion could it be? I took the truck to the dealer. The first time, they changed the front hub and it still happens. The second time, I took it in and they have had the truck for a week and seem like they cannot find what is wrong with the truck. The sound is still there.
