I read a short time ago about a clunk in the rear of the Ford f150. I have 2018 f150 crew cab. At approximately 1200 miles it developed a clunk toward the back of the truck. Especially noticable when turning left or right into a driveway and the back of the truck twisting or torquing. I have had it to the dealer 3 times. No solution or improvement.

Dropped it off today for the 4th time. Losing faith in dealer. Ford has allegedly been contacted. Any assistance would be greatly appreciated.

dont slow down

What about a loose shackle or shock? When backing up if you shift into Neutral and coast while backing/turning does it still do it?

The dealer has checked all of the shock mounts and shackles. Retorqued all chassis bolts. The truck still makes the noise whether under power or not moving forward or backwards

Time to take a ride in the bed of the truck and see if you can locate it that way.

I did suggest that to the service writer. The good news it is easy to replicate. Thank you.

Spare tire cranked up all the way?

I did check that first. The dealers mechanic also checked. Thank you

Pretty well documented issue. Likely the white spring isolator between your leafs. You can replace it or Jack it up and squirt some grease in between.

My 2018 seems to have developed the same "clunk", (rear, almost always happens while turning into a driveway either direction) For now I'm blaming it on the cold, I never noticed it when it was warmer I'll probably try greasing the isolator first, hopefully that's the fix for mine.
