Hello Scotty, I watch you every day! I have a 2011 F150 with a 302 Coyote motor. After putting it in drive, and then accelerating there is a small clunk sound. It seems there is a bit of play somewhere. I don't think it is the transmission, no issues at all with shifting. The timing of the clunk is not when I put it into D from park or reverse, just when putting my foot on the gas pedal from a standstill. Thanks!
Those only thing else that would clunk when you accelerate is a motor mount or something in your suspension. Clunks are usually transmission related. You're going to want a mechanic you trust to test drive it if it gets worse to pinpoint the issue

Actually I had brought it to my mechanic and we eliminated the motor mounts as being the problem. Thanks for your answer

check driveshafts and u-joints. My 97 pathfinder does that also. Except my joints don't have play nor does the differential. Looks like the yoke going into the transmission from driveshaft that I find play.
I'd check your u-joints and yoke. I believe you can grease the yoke. On mine you cant change that part out by itself. I'd have to change the whole driveshaft so planning on greasing it to see if it'll help. You'd have to drop the driveshaft and pull it out the tranny to grease inside yoke
The bearings may be worn on the u-joint. Check the drive shaft...

Yes I am 99.44% sure that has to be problem. Grease the splines where the driveshaft goes into the transfer case. THANK YOU
