Anyones Airbox rattle? Also rear suspension Q ?


Recommended Posts

I swear it's my airbox rattling around in the back.

If I go over bumps or jumps on the road, it sounds like something in the back is making a right rattle sound.

I tightned the bolt on the air box to little affect. Any other ideas?

Also I get a rear knocking from my suspension when I go off the throttle. At very very low speeds if I accelerate then suddenly go off it knocks from the rear.Can do it very easily using the throttle, any ideas for that?

Also a third thing I've picked up on. At around 70 MPh I get an engine whine, sounds like the whine you can get from an AC compressor but it is at 70 +.
I can control the whine with my throttle, 0% pressed and it whines completely, 10% pressed and it goes?

There are two rubber grommets installed at the feet of the air box. Are those missing? Maybe the snokel tube is loosely attached?Rear drop links and sway bar bushing are usual suspects on rear suspension.

It's surprising but wheel (lug) bolts that are not tight can cause slightly loose wheels to make some unusual noises that are not always constant. Sometimes this knocking can occur on slight overrun when travelling slowly and then disappear as speed builds up.

To locate a noise it is a good idea to get a passenger to use a stethoscope and this aids direction to the source. It's always a good start.

Will check that, what do you mean be the tie rod on the rear?

Changed the rear links today with no change.
I can quite litearlly control the clunk with the throttle.
Tiny bit of acceleration on then suddenly off and it makes that little clunk noise. I can even go up and down on the throttle really quickly and make it clunk in the back!
Engine mounts fine and tranny mount is fine!
