3.0 is super loud and shakes....what the hell
ok so this has been getting to the point where i don't like driving my truck on the highway...heres the report...on the highway my truck shakes above 70-73 miles an hour....NEVER DID THAT before a week ago...i was able to get it up to 90 mph and it would run like it would at 50 mph...my rear veiw mirror shakes so bad i can;t tell what kind of car is behind me (they all look the same) if i let off of it and bring it down to 55mph, it sounds like my hubs are locked and im doing 130 mph. (they are not) then does the same thing when i bring it back up to speed (65-70 mph) at 65-70 it is fine and runs fine...driving it in town is like she has always been...nothing has changed, just at those speeds...im thinking its the tranny in 4th gear? i dunno its an 89 pickup eith the 3.0 and an auto tranny....please help guys

Wheels full of mud,ADD not disconnecting(front driveshafts aren't balanced well).What freq is the vibration?Slow and choppy or fast and buzzing?Airplane turbulence or Lazy-Boy?Does it have plenty of power?Swing bearing?

My truck did the same kind of shaking thing, but nooo noise. i dont know what to tell you about the noise, but check your ball joints. also, you wouldnt by chance have a bent axle would you? but before you check into that, have your wheels balanced, look for funny tread wear, and if you can, see if your rims are straight and true.

I had those EXACT same symptoms on mine. It turned out to be a bad rear driver side axle bearing. It was real bad at 50mph got better by 60 mph and then was loud as hell and shook violently at 65-70mph and up.
edit: re-read your symptoms and I guess they are not EXACTLY the same but pretty darn close.

I'd say U joint. with your truck turned off and out of gear go underneath and see if there is any play in the driveshaft ( try to move it up and down and side to side). most likely u-joint. driveshaft should be tight and not have any play where the U-joints connect. and the best thing is its easy to check! i'd check it and fix it before driving anymore as if its that bad where you have extreme vibration it will eventually break either leaving you stranded or causing a ▓▓▓▓load of damage.......

I ruled out my driveshaft by dropping and driving around in 4wd. I imagine you could do that on your truck too, right? Maybe you could pull it and then see if the noise is still there. If it's gone, then you know to replace the u-joints and you've already got the driveshaft out.

ok some new signs...driving to and from work for the past two days i travel about 45-50 miles an hour...it gets up there fine and when i do get to that speed and i let off the gas completly the noise stops but if i so gently touch the gas pedal it makes the noise again...it almost sounds like a jake brake on a big rig...i let off the gas and the noise stops...hit the gas and it continues...vibrations are only at highway speeds...75 and up and u-joints are tight no play...any other ideas?

Also, nine had no play in it at all untill I got the rig off the ground, then it had the play . It also moved up and down as well.

I am having the exact same problems with 95 4runner..........I replaced the u-joints....didn't help any......I finally took it to a guy, and he says it's either a carrier bearing going bad, or the pinion bearing going bad.......I lost the pinion seal a month ago, so I figure the pinion bearing is toast...
He hasn't pulled the chunk yet to make sure,.....I'm looking for a chunk to replace it if it's the problem....
Either way it's $$$$$$
