nissan truck vibration

a couple of questions:

-under what conditions does it vibrate, ie. speed, cornering, etc.?

-how do you know it's not the wheels/tires? have you had them checked for balance or damage?

I have had the tires balanced twice it seems to viberate more when it's in a little strain. I supose it could be the engine it has 150,000 miles on it but it still runs good and does not use oil. If it is the engine it is not a solid miss. ( or skip). Any thoughts??

El Kabong - are you the same person from the Ifish site?

Are the same El Kabong from Ifish?

No, sorry.

So in other words, if you were to coast down a hill at the same speed in neutral, it wouldn't vibrate? I'd guess then that it's not a chassis problem. If the driveshaft isn't bent or something, then maybe you're right. It could be something to do with the engine.

-motor mounts?

-flywheel?

-some internal problem like bearings?

What kind of vibration is it? Does the whole truck shake, varying with road speed? Or is the vibration more related to engine RPM?

I don't think it's in the drive train If you push in the clutch in stops I must be the engine. It is not a strong viberation just enough to notice.. I have not checked the compression but would uneven compression cause a slight vib.?? It's not a skip. What do you think?

Check your Nissan dealer. I think they had a campaigh on that viberation problem. I remember stocking some damper blocks that mounted on the frame when I worked at a dealership. Kind of a NATURE OF THE BEAST situation though Sorry to say. But it won't hurt to check.Just have your vin # handy when you talk to them.Ask the service writer to check on any out standing campaigns.

I have a 97 hardbody 4x4 2.4 12v. Does the same thing and had it for 2 years now. NO service engine light and no major noise to anything other then the vib. Just learned to live with it.
