ok i have been having this vibrating thing going on for sometime.

going over 50mph on highway the truck vibrates really bad i can feel it in my seat and floor board vibrates.

the u joints are nice and tight and have a brand new trans mount.

ok i have changed:

got new tires.
got a wheel alignment.
got brand new front wheel bearings.

and it still vibates a lot .. what to do now?

help
where do i go now?

let me know thanks

The ujoints in the drive line has no play in it?

 

no play

 

did it start doing it right after you got a allignment

 

no way before the new ties and alignment

 

tires

 

hmm. Mine has a viberation but its the ujoint. Have you checked your back lash

 

have you checked your wheel bearing you will be surprise

 

the backlash from the diff the is a little play not much

 

got brand new front wheeling bearings

the back wheel bearings are tight

 

Ball joints? check rack bushings?

 

ball joints good
rack bushings good

 

could 1 of your rims be out of round, or bent? Do you feel any kind of roughness in or thru the steering wheel? You might have a bad motor mount. Do you really feel the vibration when accelerating, or just cruising over 50? Check your cv joints.....

 

its 2wd, check the strut bar bushing on the front, mine were bad on my old nissan hardbody and it would shake like crazy.

 

it vibrates in the seat not much in the steering wheel just cruzing on highway over 50mph ever when i let off of the gas it still does it

 

possibly take it to another shop and have the tire and rim runout checked, could be a bad tire, we get them from time to time at my shop.

 

ahhhh, my bad, I forgot the 2wd part.....lol

 

Had same problem on a new set of tires one month ago. Finally had a road force balance done and they found one of the new tires out of spec. Tire Rack took the bad one back, sent me a new one and paid for the balance and remounting. All this after I had a new drive shaft center bearing installed. Drives good now at all speeds. I will soon be changing my wheel bearings, and u joints just because.

 

Ok i got a one peice drivelive, new tires new front wheel berrings
the vibrating is in the rear
i rotated my tires from back to front vice veasa
u joints are tight . It does it sometime on the highway going 50 mph
+
it seems to do it more when a make a lane change or going around a turn on the highway
it all so seems to do it more to when going up hill a little on the high way and down hill to on highway
i did not take the bolt out of the bottom of the shock let on the rear end
would a bad rear shock cause it to vibrate?

 

might be your transmission going bad or your drive shaft might me bent
