245 MPH would cause any truck to shake!!!
props to the T

 

LOL :bangit: I WISH!...well maybe not

 

lol my bad. thats 20-25

 

Do share how you go 245mph in a truck without dieing and I'll be able to help you with your shake issue. (lol's to self)

 

I think mine would shake at 245mph too lol

But maybe check all of your wheel nuts are tight. could be a broken belt in your tire?. Check for any bulges in the sidewall. many things could cause it. Maybe they didn't balance them properly, but if that was the case it would probably be a bigger range.

 

Have you done any offroading, that used to happen to me when I would get a piece of dried mud clumped up in behind the rim throwing it a bit off balance

 

no. havent been offroad in about a month. ive had that same issue i havent checked to see if any lugs were busted. i assumed they would have told me when the balanced the wheels but its possible

 

How new are your tires? Them themselves can cause that.

 

they only have about 3k on them. i just started noticing the shake about 200 miles ago

 

With it being an 05, I would suggest checking the Ball Joints for wear.

 

or the rotors might be warped

 

if the rotors are warped it should be noticeable if you try braking. If it gets worse when braking, have them turned. Anyone know if these trucks can be turned without taking the rotors off? I know this can be done on cars and I don't see why trucks cannot be done.

 

I'm thinking the balance is not completely on... However, you could also have bent camber bolts too... I'd start with checking the balance again, first... You could be ever so slightly out of balance on one or both tires, or maybe even one if your rims may be slightly bent... I would have them check the rims' shape first to make sure they aren't bent, then have them rebalanced from 0 weights, then switch sides and test them out... If the shake is still there, you got something else going on... check the alignment afterwards as well... I know once I rotated my tires, I had to get my front tires rebalanced after noticing the shakes at 50+, then after that rebalance, it was slightly shaking a bit around the 30+ range, after I took my T back, the tire tech took all weights off, scraped old tape residue off, and rebalanced them from 0... No more shakes after the last rebalance...
My buddy had been overdoing his lifted T with basic suspension in Pismo a couple of months ago and ended up bending something, causing mad wobble and shake in the front end... After he took it to 4WP, their "expert" said that both cam bolts were bent, causing his alignment to be extremely out of wack... Might as well check the tie rods too while your at it...

 

alright ill start over again..haha thanks for the replies guys ill let you know what it ends up being if any of the stuff you suggested fixes it.

 

Try Road Force Balancing the tires.

 

also check the tires for out of round can cuase the sacking at that speed
and sometimes these tire shops torque the wheels wrong and cause the rim to be ****ed
