Clunking sound

I have a clunking sound when going from reverse to drive that has been there since I got it. I think it's getting worse but very gradually. Any of you have this or is it considered "normal"? I can also hear a faint clink from what sounds like the rear axle from inside the truck too but can't tell if that's where it's coming from or not.
Trying to decide if I want to take it in for Ford to look at it or not.

Mine does the same thing when you put it in reverse or drive. Its a loud clink sound. My service advisor said it was a load dampener like a load spike or something. I duno we'll see.

Is it in the shop now to be checked out or did they say not to worry about it?

I remember this mentioned on another forum and someone suggested that the slip/splines on the rear section of the rear driveshaft (where the black boot is) were NOT greased from the factory. Maybe have them check that? Mine does it too. (Did it stock and lifted, just the same.) If I were to take it in, I'm sure they'd blame the lift for the ungreased-from-the-factory slip, so I'm thinking of just doing it myself.

No it is not inthe shop, but it is going in this week to get the left front shock replaced. It has oil running out all the way around down it.. I will ask again about the clink and ask if it needs to be greased.

Got a new left front shock. They told me the clink was normal. They said they all did it, and said it was a load dampner. I asked about my truck going into regen 3 times in one day while pulling 8k lbs. They said normal also. They are checking all 08 super duty 6.4's that come in with major problems for a programmer. They are looking to cancel warranty's. Man Ford is not playing around with these new 6.4's......

Why did you get a new left front shock? I've got a squeak in the front end that is driving me nuts. I never suspected the shock but you got me thinking.

I also have the clunk... I thought I saw a TSB saying this was normal. As stated above, greasing the slip joint was the solution on older trucks. I don't know if it's the same setup on the 6.4s

I had my F350 in for this "clunk" last week. They kept it all week and then gave me a copy of a TSB that says it is "normal - do not try to repair". Sounds like it is going to come apart sometimes.
Seems to be way too much gear lash in the rear differential to me. I bet it comes apart before 36,000 miles, even if it gets a little help to do it........
