See photos...I can't tell if the caked on fluid-looking substance on the bottom portion of the shock boots is evidence of them leaking, or just gunk from the road. This is on both fronts shock assemblies.

Is this what y'all typically see when they start to leak?
They haven't exhibited any possible signs of leakage other than this, but I did just hit 110k miles on the car, so

 

Second pic looks like it's 'beginning' to seep.

 

Yeaaah, fraid so

Thanks mate

 

What year is your GS? At 110k and the known Struts leak problem it is likely not good.

Too many of us have joined and posted to this Club.

2017 w/Lux so AVS as well, for what that matters.

You have any opinion/experience on RSR coilovers versus RR Racing R3's?

 

I am not a real low drop for looks owner. I run (Springs Only) the Swift, and was choosing only the Swift or Tanabe for my 13 GS350 Lux. The Swift are not as low as the Tanabe. Based on some who had them both the Tanabe's may actually ride a little smoother than the Swift. Being they are seeming to take a toll on LCA and Ball joints and other, I would not want to run the RR not RSR coils. I drove and rode in 3 GS's with RSR, RR, and Tiens. One had the AVS compat Coilovers. Personally I hated all of them. They were hard riding, and Bounced like crazy, even bouncing you up out of the seat. lol! On a glass smooth rode no problem, till you hit the slightest, road hump, bump. dip or ill-regularity, or road change the slightest. Each were adjusted many times to improve but still the same hard, Bouncy bumpy ride. Not for me. There is also a CKS coil option. Be aware that many have had the need to rebuild the Coilover parts not very long after they used them for some reason. IDK why?

What did work really well was I ran the KYB AVS Struts, with Swift springs. It handled on Rails. Even my AVS friends were shocked driving my car. I actually took the KYB's off because it was still just too stiff and ended up with the Swift springs and 2020 GS350 F Sport Lexus factory struts. Handled well but ride was close to stock. So I may not be the person to ask about Coils because they all ride like crap to me.

Here if you search through the pages you can find many threads commenting about the different Coils, and other suspension combos.

Thanks man, I'll keep researching. Appreciate the help!!

 

They look fine. I wouldn't replace them.

 

I would change all 4 corners at that mileage. Well worth it.

 

How much is that? It looks like it could go another 50k miles.

 

110k and showing fluid outside. Eight years old, and there is a documented know 4th Gen Strut problem. You won't know how bad it was till you install new ones like those who have felt the difference. lol!
