I’ve spent the last hour reading various threads. Haven’t found one that matches my clunk.

Car is lowered 35mm front and 30mm rear. Only other suspension related change is Steeda Subframe Alignment Kit.

In the morning, no issues. I pull out of garage and no clunk. I back into parking spot at work, no clunk.

Leaving work 9ish hours later, as I pull away, there’s a single clunk noise. When I arrive home 15 minutes later, as I back into the garage, there’s another not as loud single clunk noise.

Beyond this, at low or high speeds, no clunks. Speed bumps, no clunks. In fact, the only other clunk is a harsh bump on a road I take too and from work that even makes a bit of noise in my stock ‘17 Exploder Sport.

What could be clunking after 9 hours that doesn’t clunk after 14 hours? What could clunk when backing up after driving home but not when backing up after driving to work.

Makes no sense. Car has felt a little floaty at times, but tires were a bit low, and after handling that, it seems good.

MT82 car? I have a 2017 GT, its bone stock, but I tend to get random clunks from the rear. With mine it seems timed more with engagement / disengagement of the clutch, but I hear it other times as well when just driving.

I'd check your sway bar end links to see if any worked themselves a little loose. Had that happen to me once before on a different car and had an intermittent clunk like you described

MT82. It's the right rear specifically. Occurs after I move forward in first gear after 15-20 feet and then occurs again, although more subtly, when I reverse into my garage. The reverse one occurs right away, as if the transition between driving forward for 15 minutes to reversing is causing it.

I'll take a look at that. Just seems so odd that it only does it in the afternoon at the end of the work day.

I purposely hit more bumps, manhole covers, potholes, etc on the way to work this morning. No noise. I also made a 2-3-4 WOT pull. No noise.

+1 for sway bar endlinks, happened to me but heard clunking over bumps

Check the rear axle nuts also, should be 180 ft-lbs if I remember correctly but double check that, one of mine backed out to 70 ft-lbs.

Seems to be a very common issue. Too common in fact. :thumbsup:

It was the wheel bearings. Both sides. Even though I’ve had the dealership check them 3 times over the last 12 months / 8k miles. Getting warrantied now.

That's a hub I believe
It's on the left side btw after I got assistance to listen yesterday.
I checked all torques and found nothing wrong, both on suspension and hub nuts... However, my friends first reaction who's ears i borrowed, was that it was a wheel bearing, but after some more going back and forth listening to the clunk he was less sure.
For me it's not a bearing noise, however I've never had issues with wheel bearings before so I'm no expert in that specific field.

This is from turning rear left wheel back and forth and the noise in this video is from the outgoing bearing/ cv joint on the diff.
