A bad tire with belt separation.
Loose/worn steering joints.
Bent rim.
A warped rotor (if wobble happens while braking only).
worn front end bushings, the death wobble usually needs track bar bushings but I recommend replacing them all with nylon when you do it.
Does it pull to the side? It may be your tires. Bad tires. Flat spot on the front tires. Try to rotate your tires. And see what happeneds.
There are a couple of reasons why a car may wobble between 30 and 40 miles per hour. The tires may need balanced or the car may need a front end alignment.
the noise coming from this truck is the uv goints
It means you have a fear of heights.
get your tires checked
wobble gives an indication of a front end problem. Check the lug nuts to insure one has not come loose. With the front end on jack stands, shake the wheels to see if they move. Do the same with the tie rod ends and bushings. This will show you which components have worn out.
the rear end of the the truck!! there's one on the front if it's 4X4
Typically, a low end side-to-side movement such as what you describe is caused by a slipped belt on one of your radial tires. It CAN be caused by a bent rim, but typically that would cause you problems at highway speed as well.
The term is the dodge death wobble. there is a track bar that hooks in the frame on the drivers side in front of the front axle. it looks similar to a tie rod, the knuckle gets very loose and crates allot of play in the front end resulting in an uncontrollable shake under some conditions. A lukes link is the cheapest fix.
could need a tire balancing. Also check the tires to see if you dont have a bubble on one of them
I'd start with the disk brake rotors. If one or both is warped it could cause the problem you describe.
