Hey guys new on the forum but was hopeing yall could help. I got a 97 ram 1500 with the 360 truck runs like a top below 55-60 mph once i hit 55-60 the truck shakes my fillings out the rpm dosent move and the speed dosent change the damnthing just shakes like it comeing unglued and its scared the s*** outta me so is it the death wobble or something else? Im not 100% sure about a lift kit but im pretty sure as the truck has 285-75r16 tires on it up to date the waterpump was changed all lines has dual cherrybombs 180 thermostat but the shakeing things has me not wanting to drive it

 

Try turning overdrive off when it is doing it, and see if it gets any better.

When is the last time you had your tires balanced? Could try rotating them, and see if anything is different.

 

owned the truck for about 3 weeks and just got to drive it as the previous owner pretty much left it at the shop needing a new waterpump and thermostat new fuel pump tires on the front arent horrible the passenger side tire is showing more wear as if it is out of allignment but the truck holds the road straight as a arrow under 50-60 but im not going to expiriment letting go of the wheel at aboove 50 due to the shake i watched a vid on youtube with a death wobble and from inside it seems like it is allmost spot on but hard to tell

 

oh i allso forgot to mention that if i stomp the gas the vibration goes away and comes back when i get off the gas

 

Get a front end alignment.

 

arde the allignment was done shortly before i go the truck i just found the paperwork from the shop long story short ball joint tierod ends wheel bearings brakes all way round done less then 5 months ago

 

When you stomp the gas, the TCC unlocks, and the trans downshifts. I don't think you have a balance problem at all, I think you have an engine miss. How old are the plugs/cap/rotor/wires?

If you have a tire out of balance, or something similar, gas pedal position wouldn't make a difference.

 

ok so question would a bad thermo cause it as in the thermo is stuck open and the truck wont heat up past 140-150 i noticed today as it sat that the truck dident warm up also the plugs and wires and such look newer just dont know how much

 

now heyyou a side note the rpm and the speed does not change when the truck shakes the hell outta me

 

It won't. For the most part...... On mine, I had two plug wires misrouted (wrong terminals on the cap) and when the truck hit fourth gear, and TCC lock, it felt like it was going to shake itself apart...... Simply turning off overdrive dramatically reduced the shake. Rerouting the plug wires (correctly this time....) and it runs/drives smooth as silk.

Pull a couple plugs, see what they look like. (especially number 7 and 8.) Have you checked your plenum?
