Hi all I’m new to all this. Have owned my 2008 hilux for about 6mnths and have noticed it has a bad noise. It’s almost like a grumble and gets worse as I go faster can get even worse as I de accelerate. Will change in note as I put my foot down and take it off. Had a thud or a knock in it which you could notice at low speeds but had a new centre rear diff put in it and the knock has gone. Any help would be much appreciated.
Mechanic told me the centre diff had got rid of the problem, the noise is more noticeable at higher speed . Almost sounds like a bearing is going (that sort of wind) noise is at shaft speed not wheel speed, pretty sure mechanic said when was checking everything didn’t make difference when he disconnected tail shaft and drove it on the front wheels. Again any help would be much appreciated as this is getting expensive throwing money at it to no avail.
