Before I get flamed, I did do a search and read the post with the links, but I am not sure if I have the same problem.

Sitting still, going from park to reverse no noise. Going from reverse to drive, or vise versa no noise, so I don't think it is bad U-joints.

When I let off the brakes I get the clunk, not sure if the spline needs grease or maybe a brakes are sticking a little?

From a dead stop while making a left turn, I get a little shutter/vibration. I let of the gas, then back on and it is fine. Every now and then, it does it if going straight from a dead stop, like at a light or stop sign.

My noise sounds like the other link, but when or how it happens seems different.

BTW, my truck is a 2011 SCREW XLT 5.0, 2WD.

Thanks in advance!

 

Open, limited slip, or e-locker rear?

 

hmmm... dont know for sure, I think it is limited slip, not an e-locker. I guess I can look at the window sticker. If I remember correctly the gears are 3:55 to 1.

 

Axle code is H9

 

That's limited slip. If you are getting close to 100k miles, change the rear lube. It takes 75W-140 synthetic plus a tube of XL-3 friction modifier from the Ford store. This will fix clutch chatter if that's what it is.
