Been thinking about the vibration being "intermittant", does it come and go acording to how much pressure is in the airbags? When the truck is loaded/unloaded?[/B]
I think a carrier bearing shim likely is the answer for you, but since you probably don't keep the airbags at max psi, the angle will be constantly changing. Might try a smaller shim (1/8", 1/4", etc) and try to find a happy medium. [/B]

My, My, look at all the fun I missed while reviewing Paris Hilton's video....
The shim on my truck is a block about 3/4 inch thick and is the same dimensions (W x L ) as the base of the carrier bearing clamp - roughly 1 inch by about 6 from the looks of it. I don't know what added height you got from the airbags, but my driveshaft is in a straight line through the bearing - maybe make up a couple of 1/2 or 1/4" pieces of stock and trial and error to find the right thickness before making a final shim. I have seen people talk about 'shim kits' but don't know anything about them.
Good luck, let me know what happens. Can I go back to my **** forum now, or am I gonna miss out on more fun???

All of the **** you want is right here on FTE... Just mention a few key phrases like ""Which lift is best" or "Which intake system should I use" My all-time favorite is "Which rice wagon should I trade my SD in on?" Sit back and enjoy the show, better'n Paris herself... although I've seen some of the backroom photos of (insert fav moderator or elder here) that would make you cry.
Apparently I missed the meat of the other posts, no blood in the cranium I suppose, but think you're on the right track. Tell us what you find out.

Actually the tires will have no effect on the shim required, since what your shimming is driveline angle through the bearing. This is totally dependent on axle separation from frame (lift) and driveline length

haha! right! I've bought many Ford trucks without a PSD, but I'm not going back.......unless the Bronco makes a triumphant return, and even then I'll expect to see a baby PSD as an option.

And I grew up on an Illinois farm with Deere tractors and Chevy trucks...I am the black sheep now. I have always liked Chevy trucks and really wanted a diesel but don't trust Chevy diesels as far as I could throw them. (Not far) My 98 chevy 3.4ton 4x4 ext cab has had nothing buta water pump, spark plugs, oil, and fuel added to it since it was new. it now has 135,000 and runs like new, and it has pulled a pretty heavy trailer for about 1/3 of those miles. It has only been aligned when tires were changed, and really has had nothing done to it either mechanically or cosmetically. Has been scarcely washed and waxed and driven in salt every winter, never stored indoors yet no rust. Now I have the Ford with my coveted diesel, and the bottoms of the doors are rusting, the undercarriage is pitted, it vibrates after many different procedures to fix it, gets stuck on a banana peel and had the tranny replaced (3000 bucks) at 63,000 miles. But my God does it pull a trailer.

Strange..... me? Naw, just a truck nut that piles through 150 spam email a day, pop into the forum for info and an occaisional laugh. Went into the supercharger forum and went through a very long thread between a couple of viscious nerds that degenerated into their life story.... that was weird... never thought I'd see men broken on an internet forum... these guys need a life and some serious counseling... or the PH video.
What did you find out about your vibration??

2- I doubt that your truck's propensity to get stuck has more to do with the manufacurer than with how you chose to have the truck equipped.
3- FoMoCo began using zinc in their manufacturing process when GM was still hanging fuel tanks outside their frame rails. Unless your doors were damaged, they should be rust free long after the doors of your Chevy have begun to sag.

could be front bearings???
Strjock81,
I had a similar problem on my 99. It turned out to be the axle bearing on the front wheel. It is an unsealed bearing that supports the axle. The bearing is working all the time when in two wheel drive. Try locking the hubs and driving around in two wheel drive and see if the vibration stops. Mine did and I finally got the bearing replaced along with a half shaft from the differential to the wheel. Another easy way to check it is to push on the axle as it goes into the front wheel assembly, if it moves more than about a 16th it is probably gone. Your symptoms just sound awfully familiar. I know I crawled around under my truck for two days trying to figure out which U-joint or if the carrier bearing was gone. It turned out it was in the front end. The bearing was so shot that it had rollers turned 90 degrees from the axle.
good luck.
Scott
