Metallic clunk going over bumps

I’ve been getting this metallic clunk that’s progressively gotten worse over the last year or so. It started in the front right, now I hear it on the left as well, sometimes one side or the other rather than both at the same time. I don’t hear it over small bumps like you’d find on a dirt road but rather speed bumps or large dips in the highway that case a significant compression in the front suspension. I can kind of feel the clunk through the floor too.

I don’t visually see anything loose or any signs of anything hitting anything else. The truck is a 2015 trd sport DCSB 2wd with 58k. Where should I begin looking and what am I looking for exactly.

 

Is it stock or have you made modifications? Have you wheeled it hard or stayed mostly on the road? Do you have any excess weight up front like a winch or steel bumper? Do you have a stock wheel size? What type of climate do you live in?

edit: Also, if possible, can you tell if the clunk is happening on compression or release?

 

Bone stock. Bought it used with 32k from the dealer. Original tires even. Never been off toad, strictly road driving, no mods, in Nor Cal

 

radiator support bushings.

 

How do I check to see if they’re bad

 

If you can replicate it at slow speeds with someone outside watching and listening, that may help you hone in on where and what. That's how I've diagnosed most of my random noise issues.

 

Hmmm. Without hearing it I’m not quite sure. However a good place to start is:
1) check that none of the control arms are contacting the spring, you would most likely be able to see a cleaner part of the spring of your truck is a bit dirty.
2) probably doesn’t apply to you, but check around the wheel well to see if your tire is making any contact with any part of the fender.
3)check and see if your lower ball joint is leaking grease, but usually this wouldn’t happen at 60k miles.
4)check for signs of excessive wear on your shocks, seepage, etc.
5)check your brakes and rotors and make sure they aren’t loose or misaligned.

That’s a fairly standard place to start.

Best of Luck! I’m rooting for your truck!

 

You’d have probably noticed upon looking around, but double check your CV axle boots. See if there’s evidence of tearing or leaking. A cv axle that’s worn can clunk when hitting bumps like that

 

These kinds of clunking noises can come from the rear as well and they just sound like it’s from the front. Two things I’d check, just off the top of my head, are the lower control arm cam bolts or the rear suspension for a broken leaf spring(s).

 

Check that your spare tire is tightly cranked up and not slightly loose or it moves.
Also as inflation decreases as most never check it so does the size so gets loose.

 

Something is loose it seems, but probably not enough to notice it at low speeds, only when you hit big bumps. Crawl underneath and start double checking to make sure everything is torqued to spec. I've had a few incompetent lift shops install parts and days later i've noticed clunking. Crawled underneath and noticed I could unscrew some bolts with my fingers. I know you're stock, but that's not to say something might not be torqued properly.

 

My vote is on radiator support bushings as well.
