Ok so i jacked the car up yesterday and turned the front wheels, I could here the noise slightly as i spin the wheels. Also jacked the back up and put it on jack stands, I started car and let the wheels spin slowly didn't here any noise at all. So now I'm thinking back to lexus mentioning I would need to replace my lower struts, but would that contribute to the sound coming from the front tires if too much weight is placed on them. Because as i mentioned the noise wasn't as rough when I lifted up the front and turned the tires with my hand but I could hear it somewhat.

If it were me, I would not drive the car until I figured out what is wrong, could be something simple or something major.

Jack the car up and secure with jack stands, remove the two front wheels unless the noise is only on the drivers side, I noticed the video only showed the drivers side, do a visual on everything. Turn the rotor and listen for the noise.

Did Lexus write down what they thought was wrong? These cars have shocks, not struts. And a lower strut makes no sense...
They could have been referring to a lower control arm or ball joint.

look inside the wheel and anywhere else there is motion. Is the rotor rubbing?

I would also be checking The wheel bearing...

Not sure if you are up to the task, but what I would do next is remove a front caliper and suspend it by tying a rope to it and suspend it out of the way of the rotor and wheel (don't let it hang on the brakeline), remount the tire and hand spin it again. Now the only noise would be the wheel bearing. If it is quiet, then it is the pads rubbing on the rotor and not a bearing. Remove the pads and use a C-clamp and compress the piston into the caliper so it's fully expanded, now use spray brake cleaner to clean the area around the piston, remount the pads and the caliper and wheel and spin it. Should not have a noise since the pads should not be in contact with the rotor, but let's prove it. If no noise then apply the brakes so the pads come into contact with the rotor. Again spin it. If the noise returns, but the wheel spins freely, then ignore it. If the wheel drags and makes noise, then the piston is dragging in the caliper and needs to be rebuilt. I know it sounds like a lot of work, but this will find the problem. BTW, have you ever had the brake fluid flushed?

Poqman

One other point, did you replace the pads 6 months ago with OEM?

Coleroad

But he said no change in sound when applying the brakes. This would rule out the pads, as the sound would change frequency.

Coleroad

The op should be able to grab the top and bottom of the wheels and see if there is play. If that sound is bearings their would be play.

Bgw70

Agreed Cole, and I hope he sees that step in the video posted earlier...

No I didn't go back with OEM pads I went with
Akebono ACT771 ProACT Ultra-Premium Ceramic Brake Pad Set
for both front and back. Heard they were pretty great pads.

I tried to move both front tires grabbing top and bottom and shaking but no play in the wheel, I have had that issue with my cadillac in the past with bad wheel bearings so I think that rules that out.

I did notice my tires are wearing pretty bad on the inside on the front tires. I am taking those off tomorrow and replacing the run flats for a set of MICHELIN PILOT SUPER SPORT XL. I heard the ride is 10x better. I will be taking it to Lexus tomorrow for an alignment mount and balance and to see what the heck this noise is, I'm exhausted.

How many miles on on this car?

Mine has the Michelin Pilot Sport A/S 3, Great Tires

Keep us posted with the results...

The tire wear is fairly well documented here on the forum. Mostly related to the alignment and camber (or is it caster?, I get those two mixed up sometimes). But it also can be related to front end components being worn out.

I have 227,000 on her.

UPDATE: New Tires are now on the car dumb flats are off. No More scrubbing noise, or tire noise. I didn't know my car could ride so new without them rough riding run flats. Bumps have been reduced to vey very minimum. Firestone did the install instead of Lexus because they offer lifetime alignments vs Lexus charging me $100 for every future alignment. I can't get over how well the convertible rides after driving so long on run flats. Had it not been for this forum I probably would have ordered another set of run flats. So that noise apparently was coming from the inner wear on the run flats. Thanks for all the help guys!!!
