Exhaust? Caliper?

[DBL7DS]

Happens in 2wd or any of the 4s, brake depressed or not I’ve got this rattle… notable on sharp bumps, wash board roads, etc. banged all around undercarriage with a rubber mallet. Has slowly gotten worse which would rule out rattle clips, right? Dealer said they couldn’t duplicate. Video is doing 20mph in 4a.

could be sway bar end links...

used channel locks. Flexed from pull/push vs real movement. If that makes sense. Couple of roads and I’m reminded of the noise. Other than that silent to me.

Just unbolt the sway bar and go for a drive...

Good point!!! Another reason to go tool shopping. Ex wife borrowed my tool chest and hasn’t returned it…

So update
Dealership is telling me they sourced the rattle noise in my video above to the front driveshaft…. I’m not buying, but they’ve had the truck for a week now and ordered a new driveshaft. Said it was not CONTROL ARMS OR ENDLINKS. Anyone have a rattle that turned out to be the front driveshaft? I’ve had joint slack/clunk but not a rattle. Thanks.

I had a similar rattle at one point around 50k, I put new sway bar end links on and it did not resolve. It actually ended up being the caliper bolts, not the bracket bolts but the slide pins. When I removed them and cleaned/ re grease it went away and has been fine ever since. There was little grease on them from the factory because they had never been touched before. Worth looking into for not much money. Otherwise, hard to diagnose over the internet without more info, it could be driveshaft related as well

Thanks. I get it back this afternoon. Still scratching head on rattle in my video being the front driveshaft. Any driveshaft noise I’ve been around 2wd or 4wd has been a clunk. Not speed bump pot hole rattle. Will update accordingly.

You can try checking below the bed, above the frame rail on I believe the passenger side. There’s a cast iron damper that’s there that the bushings get blown out on. When I find the picture I’ll post it. I cut the bolts with a sawzawl and bust barely got it out without having to lift the bed. Not saying this is your noise, but it may be one.
