so at about 8-15 mph a vibration starts. i know its not tire balance. i know its not because of the bfg's. its only under acceleration and brakeing, any ideas? maybe drive angles, low diff fluid, shaft balance. idk what to start with

 

try rotating tires

 

alright and if its that the vibration should move to the front right?

 

U-Joint starting to go bad?

 

honestly couldnt tell ya. i dont know what to look for. i think im just gonna grease everything up and pray that works

 

any other ideas guys?

 

do you have a lift? SYE? i'd say check ujoints.

 

5.5 RE lift, im not sure if i have a SYE.. ill take a picture of my front and rear shafts.

 

first pic is the transfer case end the second is the shaft

 

Yes. SYE atleast from eveything I know.

 

Maybe you should Check the gears in your rear end. A friend of mine had a similar problem but his kept getting faster. It was his rear gears.

 

have you changed anything recently? like discoed sway bar? i know i can't drive on road with my front one discoed because i get bad vibes at 45

 

i havent changed a thing. just bought it. so i wouldnt know if anything was changed.
