Noise when truck starts rolling

[Nap]

I have this squeaking noise that happens when the truck first starts rolling forward or backward. Thiers kind of a speed related sweet spot that makes it happen.
Seems to go away as speed picks up. I tried rolling the truck while I stand outside but I can't seem to make it happen that way. Then had some one else drive it but I can't run and listen at the same time.

Sounds like rubber rubbing metal. I thought maybe it was the leaf springs but I don't hear it when I jump on the back of the truck.

I'm pretty sure its in the drive line. I hate to goto the dealer not knowing exactly what it is, because it will never get fixed.

Any advice on how to debug this one would be much appreciated.

I have a 05 Nismo 6-spd with a PRG mini-lift.

look at your u-joints

ABS self test?

also check your CV joints and Front diff.. see if there is any play in your front axle.

I should have mentioned that I had the front propeller shaft replaced once. When that went bad it made a loud clanking metal on metal sound. I'll check the rear drive shaft and th CV's.

Put two jack stands under the rear axle and spun the rear wheels by hand, no noise everything moving freely. I started her up and put it in gear so the rear wheels would spin. Thought I heard the noise for a second when I let the clutch out but then nothing...stuck my head under the truck and didn't hear anything unusual. I spun the drive shafts by hand and they do have some play but it's not coming from the U joint. I don't know if this is normal or not.

I felt ok about driving it after looking around underneath and when I got home tonight the noise was worse then ever and happening more frequently. I think its happening all the time but at speeds higher then 15-20 its drowned out by road noise. When I hear the noise it goes away when I push the clutch in.

It's driving me crazy. If I goto the dealer they won't find it. When my front propeller shaft went bad they blamed my flowmaster muffler for the noise. I had a heated argument with the service manager and finally got a tech to go for a ride with me and then they finally admit it was the propeller shaft. I really need to figure it out before I take it in.
