A clunking noise.....
I'm pretty much a novice in this area, but I have an '87 F150, 4.9L/4 speed manual transmission. While I drive the truck I notice that, if the speed varies quickly (as if I push the gas lightly, then let off, push the gas lightly.....so on) that when I step on the gas..AND when I let off the gas....I get one distinct "clunk" under the truck. No bounce...no rattle....just a clunk.....one when I ease on to the gas...and another when I let off.
Could this be worn out bushings on the radius arm or is there something else that I might be missing?
I'd appreciate any information that anyone might be able to supply!
Thanks a bunch,
Bob

It could be radius arm bushings, mine are worn out and do exactly that when I'm in 4x4. A clunk/pop when you hit a bump is another sign of bad radius arm bushings.

Bob, I just repaired a similar problem on my truck. If the clunk only happens when pushing down or lifting up on the gas pedal, then I suggest checking the transmission mount. I had the bolts completely missing. I had to replace the bolts. I used lock washers and some lock-tite on the threads. Good luck.
