Reminded me of another vehicle when I discovered the noise I was hearing (suspecting wheel bearings) turned out to be 3 loose lug nuts (car was a beater).
Leading evidence: '3 loose lug nuts (car was a beater)' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is '3 loose lug nuts (car was a beater)' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check so far are the lug bolts' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Reported cause
(I was in OK when I nudged the curb and my destination was MO.) But on the way back west the car developed some road noise at speed that had me convinced it was a wheel bearing but instead proved to be an alignment.

Actually the only thing I've checked so far are the lug bolts.

The rear tires manifest some vibration but it is mild and often the tires are close enough to needing to be replaced I live with the behavior, but not always.

I run into this more and more often now that as the tires on my Porsche cars wear they go out of balance.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Had to go to a funeral for a college friend a couple of weeks ago. As such one of my buddies and I jumped in my '02 996 coupe and drove from SC to Jim Thorpe, Pa on Saturday and back on Sunday. Harsh weather, crusty frozen snow from storm day before. Pulling a u-turn in a snow covered intersection I managed to find a curb that extended out further than I thought, and caught both front and rear right wheels. I was going slow and don't think I did any damage.
1,480 miles later we were back home, seemingly no worse for wear. Then a couple days later I noticed a slight, speed related, vibration. Sounds/feels like its coming from the rear, but can't be sure, and feels like it is on the drivers side.
I'm guessing this has nothing to do with my snow covered curb as this vibration would have been noticed on my drive back. Car just turned 161,000 on this trip (yes, this is my DD, and I take it everywhere), so I'm guessing one of the C/V's has given up the ghost.
I'm going to put it up on a lift in my buddy's shop in the next few days, but thought I would ask if there's anything I should look for, or be wary of. Thanks!
First, congrats on two fronts: 160k+ miles AND daily driver status.
Could be anything at this point, but I had a wheel bearing going on my 986 that caused noise at speed. I was able to easily discover this by jacking up the car and spinning the wheel by hand. I could feel the grinding through my hands, even if there was no play.
Usually a wheel bearing will get worse or better when turning depending on load. Pretty easy to check by jacking up suspect corner and seeing if there is any play top to bottom or grinding sound when rotating. Do the same with the other side for comparative purposes.
May also be a bent rim, balance or alignment issue.
Actually the only thing I've checked so far are the lug bolts. Reminded me of another vehicle when I discovered the noise I was hearing (suspecting wheel bearings) turned out to be 3 loose lug nuts (car was a beater). Unfortunately it wasn't that simple this time.
I'm not so sure the rim is the issue, but thanks for the suggestion.
Would think if it is related to the curb contact you would have noticed it sooner. But maybe not. I recall in my Turbo pulling too far into a hotel parking space and just nudging the front tires against a very low curb. Car was ok the next day and the rest of the way to my destination. (I was in OK when I nudged the curb and my destination was MO.) But on the way back west the car developed some road noise at speed that had me convinced it was a wheel bearing but instead proved to be an alignment. The tech at the OK City dealer pointed out the signs of alignment problems from the look/feel of the front tire tread. I could feel feathering and roughness from the tires scrubbing. Once home an alignment had the noise gone.
My experience with my Boxster -- very limited thank goodness -- is even a "brush" with a curb can have at least one wheel out of alignment.
So my advice would be to have the alignment checked.
Also, one can't overlook the possibility the tires have worn and worn enough to affect their balance. I run into this more and more often now that as the tires on my Porsche cars wear they go out of balance.
The rear tires manifest some vibration but it is mild and often the tires are close enough to needing to be replaced I live with the behavior, but not always. Sometimes I have to get the tires rebalanced.
And more often than not I have to have the front tires rebalanced when replacing the rear tires as the fronts have gone out of balance. That the fronts need balancing again becomes obvious when new rear tires are fitted and they are properly balanced and quiet/smooth riding.
Update!
Finally got it up on the lift today and problem appears to be no more than cupped inside edges of rear tires. When they heat up its not noticeable, and I guess my recent trip put them over the edge. These are Sumi's, which tend to flat spot quickly overnight, but smooth out quickly. The cupping just exacerbated the problem. I knew something more was amiss.
The Sumi's were near replacement time, so no biggy. BIG relief!
(Overall, I like the Sumi's. This will be my third set.)
