my front end makes a clunking sound on my drivers side whenver I hit a bump,

-the vehicle does not appear to be pulling to one side

-when i jacked the single offending tire off the ground there was some slight play (1/4 to less than 1/2 inch) from side to side, but everything seemed tight with the steering linkage.

- i stuck a rod under the tire (90deg.)and pulled up a couple times to simulate bumps but no noise or movement appeared

replaced a (drivers side)bushing on the suspension arm at a garage last year. the rubber/plastic peice right under my brake pedal so that arm doesnt rattle around.

-doesnt interfere with safe operation just drives me bonkers, seems to have gotten worse in the last couple months

any suggestions? thanks mac

You may want to inspect the area of the firewall around the clutch and brake pedal mount. That vintage with manual trans had some failures where the firewall cracked and would sound like a suspension thunk. IIRC, there was a service bulletin and a repair panel to address this problem. If that is the problem, the pedal mount will fall into the engine compartment.

Another thing you may check is the crossmember rivits as they would occasionall get loose. The fix was to drill them out and replace with really good bolts. A few suffered cracks near the steering gearbox in the left frame rail which should also be checked closely. I also saw a couple of gearboxes get loose on the frame for some reason.

Now, you have a to-do list. Let us know if you find anything. A noise like that needs to be identified before you can know for sure that it is safe to drive on the same roads with the rest of us.
