Newbie with a rear end squeak issue

[SurfNaked]

First time using the site. Hopefully Someone can help me out with a small issue I have. Seems that for the past week in my short commute to work I've noticed a high pitched squeak coming from the rear (I believe) of the truck. It does no get worse with larger bumps it actually only seems to squeak on flat non-turbulent portions of road. I've gotten under the thing and shaken anything and everything I can, nothing can recreate the squeak. I know that my front dif. bushing is bad and i have a new one on order but it the noise doesn't seem to be coming from the front of the truck. All I could think of with my DIY knowledge is maybe the leafspring bushings? Has anyone else had the issue?

If it the rear interior probably the back door if its the exterior probably the leaf springs

Fixed my noise AFTER I printed the TSB's out and gave them to the Dudes at Sewell.

(Thank you F5Moab/Doug)

While they did both, I suspect it was the spring lube that actually fixed the issue.

Mine had a some mild squeaking coming from the rear springpacks that has subsided by cleaning the packs thoroughly with a high pressure wash alone. If it returns I'll lubricate as recommended, but I'm hesitant as I realize how much dirt will be attracted and trapped by adding grease to the leaf assembly.

Xlr8n, thats my thoughts exactly. did you do the cleaning yourself?
