I have an 87 4ks with an auto tranny. The car has roughly 113,000 miles. Today I was driving around and the car developed a thump thump in the front end. I thought at first it might be a flat but was not. I have no idea what it may be. I replaced font pads, rotors, tie rods, ball joints, and control arm bushings about a month ago. Does anyone have any ideas? Your help is greatly appreciated.

It does it really bad during acceleration up till about 75 mph. It doesn't seem to matter what the road condition is. I was told that I may have lost one of my wheel wieghts. Wouldn't I feel it in the steering wheel. But it has been raining to hard for me to get a chance to look. I am almost wondering if maybe my differential has got something going on internally. Thank you for your input and I will check out the motor mounts sometime today.

I found the problem tonight. It was bolt that was about an inch long and had a 14mm head.

Just stuck in the tread hanging out. Guess it didn't have anything better to do than put a hole in my tire!
