I was wondering if anyone can point me in right direction .My navara seems fine but when im on the motorway i notice a vibration kind of noise which is noticable from about 70 to 85 after i pass 85 it gets alot quieter and noise completely goes. when i slow down to 80 noise returns

Any ideas?

not got it on mine

where is it coming from ? front ? back, underneath ?

is it vibration or wind turbulence ?

I assume tyres are all OK ?
I assume no loos body work ?

its comming from the front could tracking create that noise

its not turbulence because it always completely dissapears after 85 i tried air pressure its the noise of vibration but with no vibration ?????? very odd

My money is on the UJ bearings on the front prop shaft - give it a wiggle from underneath - you'll soon know if they're gone!

Tyres...

If it was propshaft it would just get worse with speed.

I think it is your neighbours :

1/ Slowly but surely undoing your wheel nuts

2/ Hitting your wheels with sledge hammers

3/ Putting nails and screws into your tyres.


These are the most likely options.

depends if it's about resonance

I used to drive a Discovery 300tdi for (volunteer) work and at one point the steering damper had failed and this created a vibration between 55 and 65 mph , if you accelerated through it to 70 the vibration went

With live axles and steering box, yes, not with IFS and rack&pinion

point being resonance can mean a vibration goes away at certain speeds regardless of the cause of the vibration ... back to gcse Physics for you ...

Maybe a wheel needs rebalancing.

Older Fords used to get this quite a lot. Balancing the wheels sorted it for a few months until the tyres wore slightly and it went out of balance again. The real cause was worn suspension bushes on the anti-roll bars which allowed the geometry to move around at speed, until it hit the point where the resonance ceased, which seemed to be around 90mph, which isn't exactly ideal.

Probably a new goverment initiative encouraging you speed so that they can nick you.

Interesting that when you get a vibration at speed your solution is to go faster.

what's with the attitude?

the issue you brought up was specific, and is well known, it's 100% not applicable to the Navara.

Deal with it.

Having run Navara's for the last 9 years, I am pretty confident the problem is the tyres having had the same issue a few times.

you deliberately chose to focus on the example about how resonance can affect the behaviour of a system and dismissed both it and resonance as a casue , rather than acknowledge that resonance is valid casue of a vibreation that goes away if speed changes ...

Wheel balance and tyre wear. Try swapping wheels diagonally front to back. Will wear tread blocks in opposite direction. (Obviously do not do this if the tyres are directional!)

OP is far too vague as a million things in a car can create a 'vibration'. Start with the simple ones like above.

It's not just that your "council dog" stops sticking his head out of the window above those speeds is it?

Sorry.

Could be lots of things but quite likely to be wheel balance. Have you been off road? Mud stuck to inside of wheels?

yes Just had exactly the same with a Navara I have in stock.
