Exclamation Rear suspension rattle HELP!!

Ok so i have 94 2wd d21. I static dropped with 3 in block.

So my question is after the lowering job was done. I started to get this rattle from the rear of the truck. I changed the leaf spring bushings today. But the damn rattle is still there. Im lost. Anybody ever have this problem and how did you fix it? Thanks

Welcome to IN Rob...

Hang tight... or search the site, the engine does work... I'm sure someone will have input.

Check your spare tire and associated stuff. I've heard rattles from there before.

Tailgate? Mine rattles, but I can usually adjust it out. Use the left knob on your stereo; rotate it clockwise until the rattle goes away.

Well thanks guys. As for the noise its a loose metal/ aluminum tinging sound. Only on bumps. I checked the spare holder/ crank/ chain holder. Took it out. Just started tighting every bolt i could see. Also the drive shaft bearing in the middle is also kinda new.

Sure the exhaust isn't hitting somewhere? Just a thought.

Could be the heat shield around the CAT? I believe they are just sandwiched with nuts/bolts. Got a rubber hammer? Go around tapping... you'll find it.

Tailgate hinges? Mine used to rattle. The little rubber cups that kept them snug when shut were gone. Another member posted about some tailgate braided cables he got from Amazon. I ordered a pair and ditched the old scissor type stop hinge. No more rattle.
