| does it do it when under load luggin up a hill, etc?? if so its the lifters, the easy fix is to do a full engine flush then add some 'nulon lifter free tune-up) if this doesnt fix the problem then the lifters need to be replaced, but speaking it could also be your timing chain...so go to a mechanic and he will easily tell you (for free) what the problem is! |

as nodge said the lifters and or timeing chain can cause this...mine has a bad rattle but i have been told its the timeing chain and/or (most likely) the balance sharf bearing (front) but will be replaceing the chain soon and if im up to it the front balance sharft bearing aswell( if possiabe?)

If you've still got wet weather wheel nuts fitted in summer it can cause a rattle...
Seriously though- is it coming front the front or rear of the car? |

| could be shock absorbers (the metal o-ring that sits on top and when the shock loses its fluid it does it all the time), exhaust rattle, but its too hard to tell you what it is exactly, i suggest go to a mechanic and hell tell you straight up what it is for free! either that or i recon we should make a new forum on this site for video's and sound files so diagnostics like these ones are easier! Dave???? |

Most likley be your exhaust hittin on where it goes over your diff
its a tight sqeeze beetween your panard rod to floor pan arm.
if you have had a exhaust put on recentley id say that will be 100%
your problem if so take it back and they will heat and bend it to suit.
nodge a shock couldnt rattle just not possible unless either end of the nuts were
loose or had fallen of the only noise they make would be on full decompression
or extension would be a clunck and that takes a while as there inbuilt with stop rubbers.
but at the end of the day these sort of rattling problems can not be resolved over
the internet they are are problem that needs to be sorted first hand in person.

| nodg is right i also belive its your hydraylic lifters as i had a problem like this i put nulon lifter free it didnt work got a hydraylic lifter when replacing it i seen that 1 hydraylic lifter had gone the guts of it trun side ways and the push rod was suck in it. and also had signs that it had gone on take offs and when under load it would tick like mad and some times just starting it it would tick and some times it wouldnt |

Do we even know if its coming from the front of the car or the rear?
We're not going to be able to fix it for you but if you give us a little more detail we can probably suggest a couple of things to look at. I'm assuming you don't want to take it to a mechanic for whatever reason, but suggestions are the best we can do.
Unfortunately- VNs, even new ones, had a myriad of rattles and knocks coming from the body, interior, drivetrain, suspension. I'm assuming this noise is a new one. Is it definately a rattle or is it a tick or is it s knock?

If its the rear we can rule out the lifters...
Is your exhaust still solid or are the mounts on the way out? Check for movement at the end pipe. Make sure it definately isn't a knock or else it could be the uni. Other than that look for suspension components, bushes etc. |

| aight i was just readin over this post and just to set everyone strait instesd of pickin at each other: shocks and springs CAN make funny noises like a rattle depending on how old the setup is or how the suspension is set up, exhauts can make the noise too depending on 1: how lose the exhaust is at the mounts or 2: depending at what rpm the noise comes on at due to it resonating causing the vibration. my falcon had a bad vibration due to the shocks. and my mates pulsar has a lose mount near the cat converter which causes the exhaust to rattle at lower RPM's. this problem could be anything. get it checked out. find the problem and let us know wat it was so we can all benifit from it and work together instead of pickin at each other. we ar ment to be "family" here wit the same likes and intensions. i do apologise if i have offended anyone but thats my 2 cents worth. |

| the coneverter doenst have a ount, its just 2 'hangers' at the rear if the pipe and a square block where the muffler is attached, just kick the exhaust tip and see if theres any funky noises, or lever the exhaust with a bar...... |

And now for a low tech answer.....what about the boot..or the numberplate...bumper bar..parcel tray...
When i first got mine it used to rattle and buzz like crazy till i tightend up the boot latch and number plate screws. (and cramed a peice of cardboard behind it..)
..and recently the bumper would buzz on the body because of a bolt that was only on one side and not needed.i thought it was the exhaust because when i put my foot on it it would stop..but was a vibration thing..
just a thought
