First, I would like to say thanks for all of the response, haven't been on the internet for a few days so I didn't realize so many had responded.  I did take it in one more time (someplace else) to have the balancing checked and unfortunately the vibration is still there.  The time prior to this, I had them spin the worst tire on the rim and it did seem to make that one tire better.  Unfortunately, my warranty expired 12K miles ago so I don't have that to fall back on.  I did check the tires while they were on the balancer and they hopped a bit but nothing really niticable the machine they used will even tell you if there is something wrong with the rims.  At this point, I am hearing so many different things from other friends as well, one was even saying that it could be the transmission but I am steering away from that as there is no problems with the shifting.  I will however have someone look in to the CV joints.  Once again, thanks for all of the info.

gottisrt10,

In addition to the other things posted, one more thing to pay attention to is whether the vibration goes away when you let off the gas.  If you have a vibration when your foot is on the gas and it goes away when you let off, then it's usually associated with the drive shaft.  As far as you clicking sound that goes away above 30 or when you're in 4x4, just stay above 30!  LOL!!  Does the clicking sound change when you're turning?  As with the other posts, a bad CV joint will make a clicking sound, but usually when turning and rarely when going straight.  Though when you say it goes away when in 4x4, that leads me to believe it could very well be a cv because in 4x4 there is always tension on the half shaft taking up any play that may be in the joint.  It's just one of those problems you'll have to take it in for.

First, funny thing is my last name is Nelson also

Second, thank you so much for the advice, it doesn't go away when i let off the gas. It does change in 4x4 but it's bad unless I'm driving straight line, it becomes very difficult to turn, and almost sounds like grinding. This is all in 4x4 hi, but I was told that you are supposed to have limited turning when in either 4x4 mode. I always thought it was 4x4 low that you have limited turning.  As far as takin it in, i have to pay now since i have zero warranty.

... After driving 10 miles plus park and feel to see if one of the front hubs is hoter than the other. Also lift the front wheels and test for excess movement top to bottom then and side to side.

Follow the advice that lakota gave gottisrt10.  If you have any play in the wheel bearings/hubs, then as you turn, you will be putting a load on them which takes away the play.  Like lakota said, jack up each front wheel individually and grab the tire at the top and bottom, then check for excessive movement.  Then grab the tire on the left and right sides and do the same thing.  Also, do the obvious thing and crawl under your truck with a flashlight and look at the hubs/c.v. joints to see if there is anything leaking(grease) or any metal shavings.  If you can't or don't want to do that, just take it in for an oil change somewhere that will rotate your tires for free.  Then when the wheels are off, check it out.

gottisrt10,

Funny thing, growing up I only ran into one other person with the last name Nelson.  Now they're everywhere.

With all these vibration problems, I've got to think that there is a TSB for this problem unless the manufacturer is trying to keep it all hush hush.  Your problem does sound like a bad c.v.  You're steering should be noticably different in 4x4, but hard to tell in 4hi because there is no torque multiplication or a locker.  You should not notice a difference when turning left or right in 4x4.  If you do, then you definitely have a problem.  I would suggest doing the same thing I told zgatt.  Take it in to someplace that will give you a free tire rotation and ask if you can look when they get the wheels off.  Do you have the ability/tools to remove the wheels and brake assemblies yourself? If so, then you might want to do it and look very close at everything for any metal shavings.  You will also be able to spin the half shaft and feel for anything abnormal.  If you take it in, make sure you take it to a 4x4 specialist, not the dealer.  A specialist know a heluva lot more than the dealer.  Unless there is a TSB or a secret recall being performed by Nissan.  The import manufacturers like to keep recalls quiet and won't send out any notices, that way it doesn't make it on the 6 o clock news.  Toyota has had some BIG recalls in the past that very few people ever new of.  Keep us up to date.
