Mitsubishi Repair: 97 Mitsu Mirage, wheel bearings, steering wheel

Question
I am having an issue that I cant resolve. When I accelerate and deccelerate the WHOLE car vibrates. Not just the steering wheel. When I give it gas at any speed its the hardest. WHen i slightly let off almost at cruising speed it stops but let off all the way, its just as bad. I have replaced the tranny mount and looked at the motor mount on the PS, i dont know where the other is, seemed fine. Its not out of alignment or bent rims or anything that i have all ready had looked.Is there anything else that I could be over looking?

Answer
Thomas: Pulling this right out of my repair manual... tire out of round, loose or worn front hub or wheel bearings, worn tie-rods, worn lower balljoints,excessive wheel runout, tire blister or bump on tire. So some ideas to check and I hope one fixes your problem. God bless: Linda
