what is this.??
 

when im cruisin 50+mph my whole truck shakes...it almost feels like a tire might be out of balance but it doesnt do it all the time..and it only does it in od...any ideas?

Tranny time!

:argh::argh::argh::argh: yeah i would agree sounds like your tranny is slipping:argh::ouch::itsok:...o well now its time to make sure it doesnt happen again:choochoo:

Ya it could be your T/C

Has your trans been running hot?

well i had gas buner that did that and its was my drive shaft u joints but i dont know whole lot thought id thro that out there

I had that happen on the 89 and I balanced the tires. By some sort of elvin magic it stoped. I would balance before I bought a new T/C

I dont have a trans temp gauge but I think I have pretty much ruled out a tire out of balance....but im gonna take it in next monday to see bout the tranny, if it is i reckon it's time to build one..I knew it would juss be a matter of time.

CHECK YOUR U-JOINTS. ONE COULD BE LOOSE AND LOCKING INSIDE THE CAP SO YOU DONT HAVE IT ALL THE TIME...

drive shaft u joint
 

yeah check your u joints in your drive shaft I had to replace one, it didnt shake all the time at first but it did over time tell I changed it.

alignment!??!!?!?!?!

Death wobble? My '03 would only do it at high speed, usually i was in o.d. when it happened. Turned out my track bar bushing was worn out. $13 at NAPA fixed it right up

I thought it couldnt be death wobble since all my tie rods were good. Turns out the steering was tight, the entire axle was going left to right.

I have an 04.1/2 and mine did the same thing and it was my rear drive shaft. it was the u joint is was forz lol no movement. but that doesnt mean that is your problem. but thought i might add my opion. :c:

Also check your carrier for the drive shaft if the rubber is worn out it will bounce around. How many miles on it? This doesn't happen till well over 100k

x2 for the death wobble. Those 4 link front ends tend to chew up trac bar bushings. Off roading will only speed things up.

try putting it in 4wd drive and drive at 40-50. if it is worse then the tranny and rear drive shaft is pretty much eliminated.:U:


also if you suspect tires swap the fronts to the back and see if it changes.
