CR-V MK3 noise issue

[macbook]

Hi,

I am a fresh owner of the CR-V 2009. I have took the car to the honda technical checks, and suspension was spot on. However I noticed that when I driving on uneven road surface or small road holes, bumps, manholes etc I feel very unpleasant noise as all this uneven surface transfer to the cabin, like there was no suspension at all.

I don't know if this is normal for this cars, and where to looking for the reason. The suspension has been check by Honda technician with all pass checks. They found that the car is fitted with incorrect tyre size 235/65/R17, where the manufacturing recommendations are 225/65/R17. I'm just wondering if maybe the wrong tyre size and the fact they are budget tyres cause, cause I hear unpleasant noise and feel all bumps and holes in the cabin, or this could be this something else. Do you have any advice or sugestions ?

Kind Regards,

That change in tyre size will not in itself cause any change in noise or harshness.
Cheap tyres and/or old tyres can cause it. What tyres are on it and how old are they?
(To find the age look for a 4 digit code on the sidewall)

Probably the ARB d bushes and/or drop links if it only happens on uneven surfaces.. Its a horrible knocking noise..

I got away with only changing rear d bushes which solved the noise. They didn't look too worse for wear, but the noise dissappeared instantly when changed.

If there's no actual wear to be found, it might be worth giving the undersides a spray with some rustproofing solution, no i don't mean waxoyl.

I spray the undersides of my cars with ACF50 twice a year (but there are loads of products to choose from that creep and don't dry out), obviously concentrating on the parts most likely to rust on whichever vehicle, the product seeps into any bushes and suspension joints and will usually quieten down any dry joints.

Seeing as Hondas share my Toyota's tendency to underbody rust it might be worth doing for the rust reason anyway, if it shuts up the noise as well, bonus.
