I've got 98 Ram 2500 4x4 body lifted 4". It's developed a really, really bad rattle starting at 38 mph where the truck and steering wheel oscillate until I hit about 45 mph, where the problem suddenly stops, and everything is smooth above that speed.
So far, I've replaced all 4 shocks, which helped but did not fix it.
I replaced both rubber bushings on the anti sway bar. Again, helped but didn't fix it.
I found two bolts on the transfer case frame support whose boss had come off . (The bolts under the central rubber support block) I fixed that, and it seemed to fix 70% of the issue, but it still exists.
I've had it on a lift and couldn't find anything else loose or shaky.
At low speeds, (under 15 mph) there is a small squeak roughly every 4 feet. (Possibly the bed squeaking on the frame?)
What else should I be checking?
FWIW: Things worked on in last months:

FWIW: Things worked on in last months:
- New Cat which involved removing the skid plate and transfer case support
- Shocks and bushings
- New U joint on front of front drive shaft
