my jeep shakes on the highway i'm pretty sure i dont have dw i just noticed it the other day...alignment maybe? thanks in advanced for the help

 

Most likely one (or more) of your wheels are out of balance, either because of abnormal tire wear, or because one of the wheel weights fell off. Any shop that installs tires will balance for cheap.

Could also be bad ujoint or ball joint

 

Check ball joints, tie rod ends, trac bar mounts, sway bar ends, any other bushings, etc. Tons of stuff can cause wobble, and if not addressed before the alignment, will still create problems after the alignment.

 

Ujoints are usually vibrations, not wobbles. And I forgot all about mentioning tires. Now that seasons are changing something as simple as uneven air pressure could cause slight wobbles.

 

Everything these guys said start with the tires first then dive in.Front end parts if you cant say when they were last changed they most likily need changing.
