Well i crawled under the beast today and nothing was loose so i gave her some grease... there was grease in it but i pumped it all out with fresh stuff... the vibrations have stoped!!!! so maybe i dont need new u joints? i grease them regulary so idk lets just hope it doesnt get worse...
thanks every one for there help u guys rock

 

my turn...

i've got a slight vibration only while coasting in neutral and only below 30km/hr. it isn't to the point of being problematic, but i'm just curious what it might be.

 

grease it up...
does any one elses truck do this, when i drive down the road when the truck is cold and let compleatly off the gas it like lurchs so to speak wat could that be? i have no idea how to explain it any diff.

 

Odd....of every vehicle I've ever owned, when it had a u-joint issue, it change frequency with vehicle speed.

Well, atleast you found the problem and don't need a u-joint...... yet! Muahahahaha! (Yankin' yo chain, main.)

Actually, if none of the caps have cracked, the seals are still intact, and you keep it grease you'll be fine for a while longer.

 

hahahahha

 

Loose tire, maybe. Don't know....might have to just give me that truck for a while and let me look at it. A good looooong while, eh.

 

Lurching....hmmm. Sounds creepy.... and kinda kooky. Rather mysterious and spooky. But, really..... altogether ooky.

Sticky throttle cable? Symptom goes away after engine gets good and warm?

and yea once its warm it goes away

 

Oh...that was directed at Sizzlechest, but you could send me your truck, too. My 4rnr will have to stay, though. I need something to compare by, you see.

Have you noticed any loss of power lately? Erratic idle? Did this just start happening with the onset of cold weather?

 

lol i c
uh no its been doing this for a while

 

any changes in idle? or any noticleable differences in the sound of the engine?

im sure you will be fine if you dont hear any loud noises you should be alright, and maybe when it gets worse you will find out what it really is (sometimes it takes a while lol)

 

yea its been doing it for a while im not worried about it but would like to know lol thanks for the help

 

In your avatar, are you flashing peace or just saying f@#$ off? In England, that's the sign for....well, f$%^ off! lol! Either way, don't change it..it's perfect. Keep'em guessing.

Have a look at your throttle cable and linkage. If it's sticking, it will cause problems like that.
