Front Struts and Rear Shocks
 

We have a 2013 GX460 with about 91,000 miles on it. We took it to a local garage with a good reputation for an oil change and inspection. They called and said the front struts are leaking and worn out and the rear shocks are also worn out and the replacement will cost $1,175. They said the tires are cupping as a result. We've never had any struts or shocks replaced on any vehicle, although only one we've owned has had higher mileage than this. Also, the price sounds pretty steep. Any advice? Are we getting taken for a ride? We have to decide if we want them to order the parts and do the repair.

By adaptive do you mean air suspension? If so, then no, just regular.

91k on the original struts aren't that bad and at least to me here in Los Angeles is very normal.
I've had the struts leak after 60k on my previous vehicle. DIY can be done with most regular tools with exception of spring compressors which can be borrowed and an impact driver.
Compressed springs are quite dangerous if not careful. The price given appears normal for all 4 replacements. imho.

good luck.

I call bs. Get a second opinion. What are the chances are all done. You do heavy offroading?

Honestly, 90k and 5 years isn't outside of the realm of possibility for replacement, however I call BS on the price. I just added an assembled Dobinson's 2" lift and install for $1450 total, and that's a far upgrade over OEM components.
It's definitely worth a second opinion.

A second opinion wont hurt. Anyone know of any good stock OEM replacements. RA and Amazon dont really seem to stock much KYB or trusted replacements?

You may want to look at the KYB offerings. Nothing against the 5100s, but they are a bit firmer than most stock setups, and valved more digressive than linear. She may enjoy the KYB.

The entire reason shops have oil changes that they basically lose money on is to try an drum up business.
So just don't be surprised when you take your car to a place with an inexpensive oil change place and they say it needs expensive work.

I honestly doubt all 4 shocks/struts are blown and need replacement, but it's possible. Does the car ride poorly? Is it bouncy? Can you see any oil around the strut/shocks? Are the tires wearing funny (cupping)?

Even honest shops get their techs to upsale business.

I know not under factory warranty but this is criteria Lexus uses

Ha, the only thing close to offroading is if my wife runs over the curb leaving a parking lot.

The oil change isn't necessarily cheap, and the place has a good reputation, but this does sound a bit fishy. To me, it rides fine. My wife, who drives it every day, has been complaining about a thumping noise and vibration in the steering when she stops. Brakes also inspected with no issues. They say the tires are cupping.
