Grandtrek tires are horrible. That is more than likely your problem. Hunter roadforce balancing did NOTHING for these when I had them on my 80 series. Go to Michelin's..your problem will go away.

Oops...just noticed how old this thread was 
Issue is still applicable as I believe I am experiencing the same problem on my 2003 100 series.

Well SHOOT! I have had this EXACT problem for a while...'00 LX, 125K. I have searched numerous times over the past couple of months and found this thread....with no answer! Marcus are you out there? How did it turn out? Hope you didn't get a 4Runner!
So, I am getting ready for a couple of thousand mile trip over Christmas and I am wondering if I should worry about this vibration. All symptoms match those of Marcus. I noticed that the vibration goes away if I turn right, is medium when going straight, gets worse on lefthand bends. Disappears above about 55 mph.
Any ideas?

Left to right hand turn difference might point to wheel bearings. Better and worse when one side of the truck is loaded.
Yes, that's what I am beginning to think. For a while, the vibration seemed to go away when turning off the OD. So I fretted for a couple of months that the tranny OD bushings (this is an '00) were going to detonate the transmission. Now it is clear the same vibration exists with OD off, just a different frequency, and it doesn't resonate at 45 - 55 mph.
I think I am going to go for it and make the drive. I didn't repack during my recent 125K service because I get into water often during hunting season and I decided to wait until it was over. Maybe I should have...
Any reason to think the bearings would catastrophically fail with another 2000 miles of highway driving?

FWIW: The double lip seal on the 100-Series CV is very well designed and does an IMO incredible job of keeping water and crud out of the hub and spindle bearings...I've thoroughly tested mine over and over and over. 
I would think, although this is a poor excuse not to pull the knuckle and check the general condition/lube of those bearings, you'd be OK for a thou or two. With the appropriate puller its a fairly quick job/inspection.

Embarassing Update!
OK, its been 10 months and about 15K miles since my last post on this topic. Since I needed new front brake pads and had over 100K miles on the rotors, I decided to have them replaced and had the bearings replaced too.
The embarassing part is that I waited this long...but there was no side-to-side play in the front tires and the bearing noise wasn't getting any louder, so I let it ride for a while.
Truck is defintely quieter now. Maybe I was just lucky, but for others who may have the same question I did regarding how soon they need to replace bearings that are making a slight noise, I went about 20K miles more after I first noticed the noise/felt the slight vibration when turning right.
