Ok I have a few questions/probelms bear with me a bit. I have a 99 ram 360 ext cab its lifted with a ton of aftermarket parts. I honestly don't even know what all thats been done but it seems like everything that I've came across so far was done right. I know for sure it has headman hedders and aftermarket exhaust and the truck is lifted with 35's. Couple problems I'm having is that at 50-60 it shimmys and shakes pretty bad like your mashing and letting off the gas as fast as you can. If you stay on the gas real hard it stops or if you let off it stops. Awhile back I replaced the governer pressure sensor and I hadn't really driven the truck in a few months but since then it seems like the truck is a bit sluggish. Is there anyway that these things could be linked? I have no clue if the tranny is aftermarket or factory, or if there is a shift kit etc. or even if it matters. Any help is greatly appreciated I gotta start driving it or sell it the wife says and I dont wanna lose another toy.

 

Might have a tire that needs to be balanced. Does the shake even out after you get past 60?

 

Seems that over 60 it goes away. The truck dances all over the road if I go much higher then 60 so I dont get it up there that much.

 

Do you mean it's bucking and surging?

 

This is like the whole truck is shaking real hard best way I can explain it is like going over rumble strips.

 

It sounds like the Death Wobble until you mention that it's throttle sensitive.

 

My vote gets tires or track bar?

 

You would feel tires at *******ly all speeds ... the track bar problem (death wobble) is an oscillation and, as such, will only be present at a certain speed range (that's how oscillations work).
