The first thing you should do is figure out what the actual issue is. The suspension is complex and there are multiple things that can cause knocking, including balljoint failure, strut mounts, struts themselves, or torn bushings on the arms.
Next, you bought yourself a luxury car, so buy good parts. There's very little sense in buying an expensive car if you plan on throwing poor quality stuff into it. KYB makes the OEM struts and those can be had from RockAuto. This is assuming you have no air suspension.
Also, what is that sticking out of your driver's door by the b-pillar?

First of, you really should list your model year and options for any useful help and info. Consider adding it to your signature.

It's more likely that your knocking is from the control arms or other component. Regardless, you can buy the KYB's as mentioned (they are the manufacturer of the OEM shocks on the LS). However, a few of us went with aftermarket shocks such as these with good results and a fraction of the price.:https://www.ebay.ca/itm/STAGG-SHS-4-...5Ywghy&vxp=mtr

I put about 40k miles and two years on mine and they were great.

A set of KYB's will cost approximately 5-6 times the price, but some will say it's worth it. As i said, my setup worked as good as the OEM set. Not everyone wants OEM or to spend more if they don't need to.

As already stated, this post assumes you have non-air

kalo, more likely you may need one or more control arms replaced as the ball joint or bushings can go bad, unlikely a shock as they can last a long time unless start to leak

best maybe is to find a good indy mechanic you trust and have your car put on his lift to look at each control arm and the shocks for leaking

if can see which control arm is moving a lot that is the one making the noise to replace

OR, consider doing what I am about to do on my 07, replace all 8 control arms knowing you will be doing it pretty soon anyway

and buy the arms from like rockauto and have your own mechanic replace them rather than the dealer, thousands more dollars, remember they need to be preloaded and torqued when replaced

If you are around 100K miles then it is about time to change the struts. There are plenty of inexpensive options out there and even an entire strut assembly with springs and mount. I believe all the struts out there are the standard twin tube design. KYB gas ajust is a Monotube design and an upgrade. I changed all of mine to KYB and the ride is phenomenal even with 19 inch wheels. I plan to keep my car for a while and also I did 95% of the labor so I went with KYB.

Those are $160 shipped. KYB is around $400 for the full set, especially if you use discounts like they have from JEG. Even OEM can be had for around $190 per strut, which is still under the 5-6x figure you came up with.

KYB is the OEM manufacturer and they sell an aftermarket shock. I just installed the aftermarket front KYB shocks on my new to me 2008 LS460L. The difference in ride quality is very noticeable, the front end has a lot more control than before. The ride still retains a "floaty" feel over smooth terrain however they stiffen up and control fast wheel action (bumps/potholes) very well without becoming harsh. I hope this helps.

KYB Gas-a-just

Don't recommend the ebay specials (first-hand experience)... I suggest you go with RockAuto and bring them to your mechanic to install and reuse OEM springs etc.

If you take it to the Lexus dealership, I bet they'll reseat it for you for free.

As far as the control arms, MOOG makes arms that come with a lifetime warranty and can be purchased from Home Depot or Autozone/Advance Auto, which means if they ever fail you can have them more easily replaced by just going to the store. Some people will try to push bushing-only replacement, but that does not fix the balljoints and we have more negative evidence from people than long-term supporting evidence that they're any good.

For struts, I'd buy KYB. They make the OEM parts and they're a quality company that has been around for a long time. It makes no sense to me to try to save a few dollars with aftermarket companies like STAGG, who when you do a search you find some very negative reviews on BMW and Mini forums about how they either died after XYZ miles or they actually physically bent.

How much do you love your Lexus now Curious what that the final quote was. I think the mechanic wants you to change everything to eliminate the sound.
Go on Lexusdrivers.com to see the Lexus service history.
Can you do any of the work yourself? Look into the wheel well at the top of the wheel to see how the upper control arm rubber bushing look like. If you see cracks in the rubber then it needs to be changed. I'd start with the upper controls arms and front sway bar links. You would be surprised that a bad sway bar link sounds like a blown strut. One time I purchase a defective sway bar link that went bad after a month. Then I prematurely changed the front struts and the knocking was still there! I took off the bad sway link and drove around without it and the noise was gone. Had no problems getting a replacement from Rockauto.

You can purchase everything you need from www.rockauto.com. The Lexus OEM parts are far too expensive. I just picked up the upper front control arms, I picked Mevotech brand. The install is also relatively straightforward, all of this can be resolved for a relatively low cost.

I'll just repeat that you should verify your upper control arms before you replace anything else.

I've gone through several control arms (cross country road trip between) and my front shocks are still great.
The upper rear ball joints seem to go first in mine, followed by the forward arms' bushing.

The noise from a bad control arm ball joint is much louder than you'd expect from the way the part looks.
You'd also feel just a little play in the steering (maybe 1/8" of play if there's a really bad ball joint(s))..

Diagnose properly before you start. The shock replacement is much more labour than the control arms...

I just replaced the rear struts after running the car for about 500 miles with only the front struts replaced. Doing the rears had a tremendously positive effect. I was not sure they would really make much of a difference before doing the work, but now that they are done, there is a dramatic change. The car is far more balanced, and actually, the float and dive I was still experiencing in the front has been further reduced since swapping the rear shocks to the point where now it is very minimal.

Replacing the rear struts was also a real pain, this was the most challenging rear shock replacement I've ever performed due to the complexity of the rear suspension and that the control arms have a "pre-load" which pulls the wheel hub upwards above the mounting location for the bottom of the strut.

For anyone planning to do this work, do yourself a favor and spend $20 or so to purchase a 10' long "black pipe" at Home Depot (the kind used to carry natural gas), and a short block of 2x4 wood, as you will need these tools to use as a lever to push down on the wheel hub to get the strut back into mounting position.
