2008 hilux grumble and slight knock

Postby timbo86 on Sat, 14 Jul 2018 12:58 +0000

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.

Could be lots of things from wheel balance to gearbox bearings, or worse. I had what I thought was a bearing on the way out but luckily when I was servicing it I noticed a wheel weight broken in half and one next to it missing on the inner of a rear tyre, didn't associate it with the noise but after having all the wheels balanced the noise went away.

Not saying its your problem but noises are sometimes something very simple and easy to over look, its human nature to expect something complicated.

A dodgy mechanic could have had a field day with my bank account.

My advice, find a decent mechanic.

.
The mechanic I took it to had another hilux and he swapped the wheels to see if it made a difference.
I just want to be rid with it now but how would I even be able to sell it. Wouldn’t want to rip anyone off either.
It has a 2inch lift and was thinking maybe something to do with that but from what I have read that usual makes the drive line play up. The problem is when he disconnected the tail he said made no difference

Sr mate
Can feel it abit when I break. Can change the tone when touch the break on and off
It’s like the break is the noise or hold wateva is making the noise nice n snug so doesn’t clog around

Could be a front wheel bearing or cv joint, could be a stuffed uni joint in the front drive shaft. Find another mechanic to have a look at it.

Will definitely be finding a new mech. I’ve had the front drive shafts re placed as well as tail shaft and front wheel bearings. Wether they have missed something or haven’t installed something properly would surprise me.

You say you think it has something to do with when your breaking, try applying your park brake and see if the noise is there, narrow it down to front or rear maybe.

Not sure if it has something to do with the break just changes when I’m on or off the break like on or off the throttle.

I've used a gopro on a magnetic base to isolate these problems.

It takes a bit of patience but it can help a lot.
I might be wrong.
