My jeep pulls to the left when i push my brakes, it pops bad in 4x4, and vibrates real loud after 45mph, i think wheele bearings but not real sure.
Any advice?

 

Could also be a ujoint

 

Its the u joints I just fixed mine yesterday it was doing the same thing

 

Right front brakes not working properly or left side grabbing (warped rotor).

Transfer case or front drivetrain (u-joint included) FUBAR.

Tires out of balance or death wobble from poor lift job.

Please include more information: basics (year, differential types), mods, lift, tire sizes, and recent maintenance information at a minimum.

 

As far as brakes maybe a rotor,warped rotor is more of a shimmy or shake, while pulling is more of the left side caliper sticking,as for the rest use above.
