It started about two weeks ago. First time I heard it I thought I ran something over but I'm usually good at spotting things on the road and avoiding them so I didn't pay it too much attention. And over the past few weeks I heard it a few more times. It seems to happen only when turning left at about 10-15mph with the wheel almost fully turned. It sounds like it's coming from the front right side (but it's hard to say exactly). I checked the front right wheel well and couldn't spot anything too alarming except a straw like fixture just hanging their. I checked the driver's side and it doesn't have it. I have no idea what that thing is hanging and if it has anything to do with the noise. From everything I read online it sounds like the CV joint is the issue but upon my brief inspection it didn't seem to have any issues.

Have a 2002 430LS, experiencing similar symptom, at low sped, turning hard left, (turning right no problem) left wheel literally jumps up and down while turning. Drive over a very short distance, cannot replicate, happens every time. Steering Rack has slight leak, related issue? Thx
I have a 2017 Lexus IS 350 F Sport AWD and have experienced this issue as well. Not sure what this can be attributed to, however it seems to occur during mild acceleration between 3000-4000 rpm during gear changes. I’m glad I am not the only one who has experienced this. Other than this minor annoyance, the car has been bullet proof.

Not mine, unfortunately. Besides this issue I've also had acceleration issues which was the cause of not one but two vacuum regulator valves (both replaced under 20k miles). And after the second "fix" the car does not feel the 100%. There is still some hesitation when accelerating at times. Really such a shame, I had higher hopes for this car being a Lexus and all you'd figure it was more reliable but it isn't. Not too mention the few other issues I've had with it when the main display would freeze up, and also an A/C issue where the temperatures were set to an identical temperature but the drivers side was cool and passenger side hot. Had to turn off the car and turn it back on to work normally again. Mine is just a base 200t and overall I love it even without all the packages which I don't have (blind spot, cooled seats, etc). It handles great, looks pretty good, but this engine is not my favorite. The numbers that it outputs I'm totally fine with, but it's the way that the power is delivered (basically no power under 3K RPM) that I'm not too pleased with. I'm also not crazy about the way the engines sounds - that ticking 4cylinder noise is awful. Honestly wouldn't recommend this engine and would not want to be it's owner past 100K miles. I would even be willing to "downgrade" to the new IS300AWD which has the 6cylinder with less torque. And is Lexus ever going to update their UI it looks like it's 10 years old.
Hey guys, that tire hopping/skipping sensation you're noticing is totally normal for cars with suspension/chassis setups that are more sport/performance oriented. All GS models do this too, but this isn't exclusive to Lexus. You'll find this behavior in Porsche's and other performance vehicles.
If you'd like to know more about why this is happening, this is due to what is known as Ackermann Steering Geometry

I remember I noticed this tire skipping (before I owned my IS 250), a 2015 Porsche Boxster S.. when you would make a hard turn on the right, it felt like the tires were skipping and I experience the same thing in this car now (never in my old Corolla).. I think it's because there are thin tires
Didn't read the link but skipping is normal. One tire is not the same angle relative to the other. i believe this is due to the pivot geometry of the dual balljoint lower link. BMWs and Mercedes have this too. Keeps the suspension compact and aids in a tighter turning circle. it'll wear your tires but only if you drive full time in a circle. at normal angles/turning, it doesn't matter =)
Actually here's a cool GIF animation of the F30 328i showing what I am talking about:
Except BMW uses a thrust arm instead of an LCA (Bmw used to use LCAs) I suspect the next IS will use a thrust arm. industry standard for the class now. we'll see!

No. It is not due to thin tires. If you re-read my post, I told you exactly why it happens. Typically it occurs at full left or right lock and when the tire passes over two different textured surfaces. So a very common time to notice this is while parking when the tire is passing over the painted lines and pavement at the same time. This is when you feel the effects of the Ackermann Steering Geometry.
