Thank You for posting what you found out. I have had my 2020 pro in 3 times for this being told nothing is wrong. Which makes me laugh since I have over 20 years in the Dealer Service industry. I knew they were wrong. But being an odd cold only noise that goes away usually after driving awhile I let it go till I could figure it out better.

So I just realized I am having this exact problem on my 2019 TRD Pro. I heard it all last winter but it went away as the temperature came up in the spring. Now I have been hearing it again this winter. Unfortunately, I’m at 38,500 miles now. I assume Toyota won’t help me and I’m out of luck?

Are there any actions that Toyota is taking claim for ? Fox ? ... this is BS

i have a 2021 TRD Pro which displays the same "thump thump thump" noise (its a non-metallic sound more like an exhaust pipe bumping against the floorboard). Also, it involves two or three "thumps" in rapid succession as i ride over rough pavement at slow speeds. Any ideas?

Is there any updates on this issue? I have a 24' Pro with 800 miles and my shocks clunk at low speeds when cold. I brought it to my dealer and they found nothing wrong but did admit they have no clue what they are looking for because they don't see many Pro's come in for service. I can put my foot on my running board and rock the vehicle pretty easily and you can hear the clunk. Also, while sitting in the driver seat I can rock side to side and hear the clunking just from my body weight. I read that after the redesign of the coil perch in 2021 that this issue is gone but apparently not. Weirdly, complaints of the shocks on forums kind of disappear after time frame.

Did you leave it so they could find it? Don't ever settle for "We don't know." Demand a rental, tell them you guys keep it till this is fixed, get the SM involved. Just say, "My new 60k truck is making a totally unacceptable knock noise, YOUR job is to find and repair it...call me when it's done."

Unfortunately you can't pull punches with a dealer, they'll run right over you! Any resistance at all and you go straight to the SM or GM if needed. Service advisors are geared and conditioned to blow people off with noise/rattle concerns as they are time consuming, unprofitable, and no techs want them, so they do their best to shoo them away.

Hello. So my 2021 TRD PRO has had 3 FOX shocks replaced. 2 under warranty. The 3rd they paid for the shock but I had to pay the labor. Once again I have developed a clunking sound at low speed. When I’m traveling on highway or higher speeds you don’t hear it or feel it at all. Only at low speed like in parking lot or backing out of garage. You can feel it and hear it. I called fox who said that they designed them as per Toyota engineer specs. They said the problem is nitrogen leaks out since you Toyota pecs didn’t use a valve similar to tire valve to fill them with nitrogen. Fox said they would send me a kit to repair them and they would have to be refilled with nitrogen. Never received anything and never heard back from fox. Not impressed at all. I love my truck. Pushing 89000 miles in 2 1/2 years. No mechanical issues other than stupid shocks. I want to replace them. I’m looking at Eibach 2R. I want similar ride quality or better with less headaches. My 2017 TRD off-road had tociko factory shocks and never an issue. Any bombproof shock recommendations would be appreciated. Most
Y highway ride with light off-road. Anyone thinking of buying a pro get the TRD off-road and swap out suspension. Cheaper and no headaches out of the box.

Hello,
I'm new here and have a 2021 4runner TRD Pro that seems to be having this same issue (with only 21,500miles!!!). I took it in to the dealer in December 2023 because I was hearing the clunking on the drivers side. The dealer replaced the drivers side shock/strut under warranty and the clunking sound went away. Fast forward to this past weekend (Nov 2024) and now I'm hearing the clunking on the passenger side. To say I'm beyond upset over this is an understatement. I read in several forums that this is a common issue in older TRD Pros and was supposedly resolved for the 2021 model year. This is apparently not the case and the issue is still ongoing. Unfortunately, my 4runner is no longer under warranty and I was shocked to find out that a new shock/strut would cost upwards of $900-$1000 + labor!!! I read in the TSB regarding this issue that both sides of the shock/struts should have been replaced at the same time, but unfortunately I was not aware of this when I had it serviced while under warranty and now I'm stuck having to repair a ridiculously overpriced shock/strut out of warranty.

What I would like to find out is if anyone knows exactly why this issue occurs and if there is a fix for it other than replacing the shock/strut for $900-$1000 + labor. If there isn't a fix, I would rather replace the garbage Toyota/Fox parts for something that isn't going to have issues everytime the weather turns cold, perhaps a Bilstein, King, or Fox aftermarket alternative that doesn't have this reliability issue.

Sorry for posting this in an older thread, I thought this was a good place to start.
