Clunking sound

I have a '78 F-150 and I recently started noticing a clunking sound when I pull into my driveway and hit that little transition from the street to my driveway. I hear it the most when I am backing up into my driveway---and when I get to the front tires---CLUNK! What is going on? I have new coil springs and shocks in the front. Any insight would be greatly appreciated.

Well get under there and look and feel for something loose, broke or disconnected. Have a person stand next to the truck, as you back in and try to pin point the sound as you reproduce the conditions. Dvrs side, passenger side, rear end, front end...

Have you got on the front bumper and did a bounce test? Did you use the shock absorber rubber bushing stack and washers correctly?

Mine was not so much a clunk as a snapping. Turned out a brake pad anti rattle clip was gone.

While checking the aforementioned items, check your radius arm bar bushings. Bad or missing bushing will cause the clunking as the forward/backward load changes on the front tires

Does it clunk when you go into a gear from park or neutral?
