Occasional Clunk Noise

[BigGreen06]

Over the last week I noticed a slight clunk noise when I shift from park to drive or vise versa. I'm not sure if that is a problem, it doesn't seem to be an issue, and it is only happening occasionally.
Any opinions/comments are welcome.

So do you feel this clunk sometimes when you come to a stop, and also when you take off? Or just when you shift from park to drive, or when it shifts? Where doesit feel like the clunk is coming from?

Sounds like differential gears..maybe U-jounts???
I would check for slack in the gears though.

i would definately check the u joints....

to properly check them you should set the ebrake and take the driveline out...to take any load off of them...

Is it a 2 peice driveshaft, IE with a carrier bearing?

I have an 02 and I feel the clunck when I come to a stop or when I take off. Any ideas of what that may be?

Have you shaken down the front end? Could be a bad balljoint, bushing, or maybe a tranny mount.

Sounds like.....You need to grease the spline on your 2 piece driveline. It's easy.
Find the center support bearing, just to the rear of the bearing is a rubber boot. Make 3 marks, one on the driveline in front of the boot, one on the rear portion of the driveline behind the boot, and one last mark on the rear differential. Take the clamp off the rear portion of the boot, if you're careful you can re-use the clamp. You can either buy the $37 pint of teflon grease from Ford, or do what I did and go to your local auto parts store and get some GL1 Slick 50. Grease the splines and re-insert the male portion back into the female portion, lining up the marks you made, tighten up the clamp and enjoy clunk free driving. :beer2:

No, its just when shifting between Park & drive, and sometimes reverse. But I have noticed a little bit of a hard first shift. I don't think it could be a problem w/ my U-joints, I had those go on my previous truck, so I'm well aware of what that sounds like.

I would bet that its the U-joints, your truck is doing the exact same thing my 03 dodge did, it even shifted hard in 1st like urs. took it to the dodge house and had them replaced and it was the joints..
