Seems to be happening on PRO Tundras too. This thread seems to suggest it is the UCAs that is making the noise. Popping sound in front end? - Page 3 - TundraTalk.net - Toyota Tundra Discussion Forum

I also hear the clunk on the front left side, but dont hear it often.
No noise coming from the rear. I have 98 miles on it. Being that i have an 8yr warranty, im not going to sweat it. When it goes in for its first service and if i still hear it, i will mention it to them.

I too have noticed that a clunk coming from the left front has manifested itself as the temp dropped. Ive owned my 15' Pro for almost a year now and have put close to 10k miles on it. I started to notice a front end clunk at lower speeds when I'm going straight but it was odd because it had only occurred when it was colder out.
I jacked the truck up to see if anything was loose and found 2 of the skid plate bolts hanging on by only a couple treads (curtesy of Toyota technicians) but nothing that would cause a suspension clunk.
Having diagnosed and driven hundreds of customer vehicles with "clunks" I would have to say it sounds more like a lower balljoint or a control arm clunk but who knows... As stated above, I have 7 years of warranty left so I'm not too worried about it. Although it would be nice to know the source of this annoyance...

Some do not have the clunk but others that do not have it want the clunk.:der:

I have the same clunk as everyone else. My experience as follows.
Purchased 10/28/15 no clunk also very warm outside in FL at this time.
Installed 2in lift from Toytec. No clunk.
Late December made a road trip to Weirton, WV. Average morning temp was around 36-40 degrees. Pull out of hotel parking lot and clunk from driver front. Can be heard and felt in the floorboard.
Sound and sensation are noticed mainly from driver front. Every once and awhile i'll think I hear it from the passenger front but i can not confirm nor deny.
I can replicate it consistently driving over the rise from driveway to foundation in my garage since its about .75in high and sharp 90 degree angle at about 5mph. During this test its very audible from the driver front.
Im no engineer but being a service tech in the car business for the past 9 years ill sniff around and see what i can find. My first suspect will be driver front swaybar link. I suspect that because if i drive say 40-50 mph on a packed dirt road you can hear it knocking away from small movements in the suspension. Plus its an easy test. All things being equal in life the simplest answer tends to be the right one.
UPDATE.... Disconnecting sway bar had zero effect on the clunk.

Any clunk updates???
New to the forum. In fact, my reason for joining the forum today was to research this "clunk". I have a 2016 TRD Pro with 3000 miles on it... and I'm experiencing this clunk just as everyone else describes. So, have there been any updates? I've had it up on my lift and can't find anything out of the ordinary. I also took it to the dealer last week and they didn't see anything wrong either. But, none the less, the clunk still haunts me. 4Runner drives and handles great... just this damn front end clunk coming up through the floor board is driving me nuts. Feels/sounds like a loose strut or a bad bushing... but I just can't find the culprit. Has anyone had any luck with getting any updates from Toyota? I may investigate the shock bushing that a few people referred to. Thanks in advance, great forum!

Interesting. We're not the only ones with clunk.

Bilstein shocks clunking?
I googled Bilstein Clunk.

I just recently received my 4R TRD Pro and mine has had the sounds from day 1....I thought It was just me getting use to the sounds but this... is a problem I now have 850mi and its not went away. I have a service sched for tomorrow. I'll keep you posted.:cry2:
I'm new as well and knew nothing of this clunk until I came here. I just got my 16 pro runner on Saturday and I've taken it over bumps, potholes and everything to see if there was a clunk sound but I've heard nothing so far. I really think it has to do with the temperature. However there are some who claim to have the clunk in higher temps as well. My theory is it might be 2 part problem. I'm no parts guy and you guys may laugh like crazy at my newbness regarding car parts but my theory is most vehicles are suffering from the oil used in the bilsteins getting too cold and therefore the shocks don't perform as well and when you hit a bump it doesn't cushion as much and you hear the clunk. Again I could be way off! Now the second part might only affect an even smaller number of vehicles. This 2nd part may have something going on mechanically besides just the shocks which is why it happens in warm weather too and also why it still happens even when they replace the shocks with a different brand. However you would think they would have found something by now that was wrong if it was a mechanical issue but who knows. Just my 2 cents, feel free to rip it apart haha.
Good luck... let us know what you find out tech. I took mine to the dealer as well and they gave me the usual "could not duplicate" answer. Laziness. I'm curious if anyone has solved it by tearing out the factory susp. kit and upgrading to an aftermarket lift. I'm starting to agree with the cold weather theory... it's been cold here and now it really sounds as if something is going to drop out the bottom. Everything is torqued to spec and I see no issues under there. It's driving me crazy... The sound is so apparent that you'd bet money on finding something jump out at you like a loose shock or something. I printed out this entire thread and I think I will deposit on the service writers desk next visit to the dealership 
Your theories definitely make sense Jaden... I've considered the same myself. But, the clunk is such a "mechanical" sound that I'm starting to lean away from the oil theory. It's almost as if there is a bad bushing or a shock is making contact with the frame. Again, everything appears to be snug and I see no conflicts under there. Quite the mystery Some days it's not too bad... others it feels like the suspension is going to fall out. I can hit a speed bump head on under 10mph and it feels as if something is going to come up through the floorboard. It seems to be at lower speeds. We've had my 4Runner in my own 4x4 shop and we're kicking ourselves in the ass that we can't figure it out.

I don't think it's a coincidence the 2017 Tacoma TRD Pro has Fox vice Billstein suspension on it. (I'll be curious to see if the 4Runner and Tundra TRDP models also get the FOX treatment...)
Companies as large as Toyota do not part ways with established subcontractors for no reason... While I'm sure Fox told Toyota they could supply the suspension cheaper, I'd find an awful big coincidence this change came following 2 years of clunky front suspension...
kinda like Toyota switching head gaskets on the 4Runner in the 2005 model year but there wasn't a supplier quality problem there... again, awfully coincidental.
The good news is the clunk doesn't appear to be a safety issue but it is concerning that no one can figure out what is causing it (which leads me to believe it's internal to the strut/ shock)...
Maybe the Toyota Engineers and Fox worked together to prevent this clunk by designing in the internal bypass feature... do the billstein's have this feature? If not, it may make sense why Mike Sweers was so excited about it at the Tacoma TRD Pro debut (I think it was mentioned 10 times in the 2 videos I watched online...).
Then again, maybe it's all just a big coincidence.... the likelihood is though we'll never find out.

I too immediately thought of the clunk when I saw that the new Taco Pro has a Fox setup. If the 17 T4R Pro gets the Fox suspension and there is no clunk issue, I say we all deserve a free swap-out for the Fox. Who's with me?

Maaaybe, but... I have the clunk with Icon and I've read of others with varying suspensions also have the clunk. Bilsteins are most popular but it's not strictly limited to them. Maybe it's the design of the shock? Maybe digressive clunks and progressive doesn't, so maybe fox wont? Lots and lots of maybes but so far no one’s been able to pin down the exact cause that I've seen :/
Also new to the forum and new to 4runners in general. I have a 2016 TRD Pro on order and will be trading my 2012 Rubicon Unlimited. I know we are talking different vehicles all together but thought that sharing my Jeep experience may help. For the first year of owning my Rubicon there was an awful clunking sound that occurred anytime I went over a bump. Similar to the TRD clunk, it sounded and felt like it was coming from the front end and could be felt in the floor. After numerous checks, I couldn't identify anything loose or rubbing in the suspension components, skid plates, etc. After some additional research, I found that some people found this clunk was actually coming from the driver's door latch. The solutions were to either realign the strike point or put a small amount of felt tape around the striker. Sure enough, I gave the tape a try and have not heard the clunk for 80,000 miles (other rattles, yes, but not the clunk). Just wanted to put this out there as it sounds like a similar situation to what I dealt with on my Jeep.
