why does my dodge 1500 shake violently?

[Handyme]

i have a 1999 dodge ram 1500 4x4 ive had for like a year now? its lifted with 37" tires? for like the past month now everyday i drive it its starts to wobble from side to side violently only somtimes not all the time. the back feels like its going to fall apart. it does it when i accelerate between 30 and 50 mph. can anyone give me an idea of where to start. any help i would apreciate.

check your wheels, they may have bumps and bulges, so the car will shake violently, the faster you go. you can also check your shock absorbers and your suspension.

there are a few problems that come to mind:

ball bearings
wheel balance
needs new tires

transmission is probably gonna go out soon. same thing happened to my brother
