I have just skimmed a road test report that claimed the car is exceptionally quiet on the road...
By now the tyres might have been changed from the original specification - some tyres are very noisy and assuming the wheel bearings, etc. are ok the tyres are the most likely culprit. SUV tyres are expensive and good ones are very expensive so maybe the tyres are now not such high quality or are off-road or combination tyres rather than road tyres...
That is something to check and if it isn't a matching set of four, that can increase noise too. Ensuring the wheel alignment is correct is important for smooth and quiet running and of course the tyre pressures must also be correct.
Check the door seals and ensure all the doors and tailgate fit properly and are correctly adjusted and ensure all the body plugs are fitted and similarly any grommets and gaiters.
Sounds like the tread design of the tires..some tread can make a lot of road noise on blacktop and cement...try this,find some newer blacktop and run it at road speed..note noise and the try it on older blactop or cement highway..it changes, it is the treat design..this is very common on truck tires and sometimes passenger car tires...if you live in a snowy area..do the test on a snowy road with no salt etc.that too will quiet noisy tire tread also ..good luck...
High road noise comes from over inflated tyres---tyre tread pattern---tyre construction (ply rating). It comes from hard insulators in the suspension pivots(rubber/ plastic bushes )If the shock absorbers are worn or seizing up the extra noise is transferred to the body You have the year as 2014 but I suspect you meant 2004 in which case the rubber bushes may need replacing as the insulating qualities would be lost due to age.
check tyre pressures are even. tyre tread pattern will cause noise that increase with noise (off road pattern are noisy while highway pattern will be quite) Have the wheel bearings check for condition.
New cars have rubber sunspension bushes that absorbe a lot of road noise. Check to see if someone hasn't replaced the suspension points with neoprene bushing. This is a hard plastic that will not absorb the road noise. The other part of your problem will be the tread pattern of the tyres as they are designed for off road use but will howl on sealed surfaces. Experiment with tyre pressures as a few pound up or down may make a difference. Talk to a tyre dealer for advice on this
tyre noise depends on the tread pattern/road surface material.so it is a bad tyre depot that cannot tell you which are quiter than other makes,same as ones that last longest. most customers buy the cheapest they can get and complain about the car...)any block pattern tyre will be noisy(look at the tread pattern on a limo)the only way you can be sure of getting a quiter ride is to email the maker direct.BUT be warned you may pay 3--4 times the price of a "standard tyre" and any suv is no limo......no block pattern, no grip in mud/snow....
Would like to reduce the road noise, any idea
