Mitsubishi Repair: Mitsubishi problems, rear axle assembly, mitsubishi galant

Question
I have a 92 Mitsubishi Galant and it smokes on the rear axle assembly when driving plus loses power while driving.  The timing belt has been changed along with the drive shaft.  There was nothing wrong in neither place.  Plus there is also a vibration while driving the car.  Can you help me out?

Answer
Hi Darrell,

Sorry i can't help you on the rear axle but send me your engine size and i know a guy i work with whom i can discuss this with and get this problem solved for you.
On the vibration thing,If it's a constant thing or it gets worse when increasing speed you have the problems in your tires take it to a tire dealer and let them check for out of balance,out of round or belt separations..
