lx570 rear shocks leaking? (1 Viewer)

[kyle94109]

Brought my 16 LX570 95k miles to a a local repair shop that specializes in Japanese cars and they recommended I replace both front shocks and struts. & rear shocks.

Don't want to do this repair just yet. I've read that GX460's will leak an inch or two and it's normal wear but not a need to replace. Trying to find an article that that is the case for 570's too.

Here's some pictures they included of the front shocks and struts. Shared Condition: Time and Mileage Leaking & Recommended Action: Suspension - Both front shocks / struts replacement with upper mounts

I’m not to the point of saying they are taking you for a ride, but most shops have little experience with AHC and shouldn’t be touching it anyway. Your shop not knowing all of that looks fine for a vehicle with that mileage reinforces my belief.

Basically.. decline the repair and keep driving it until you have an actual problem.

I declined the repair, I need to do my own research before dropping that kind of money on a repair. First time at this shop.

I am now at 165k and have not replaced mine. They look about the same as your pictures. I flushed my ahc fluid and just kept an eye on the level. Haven't noticed any loss really. Based on the threads here - replacing the globes seems to have more impact on overall performance than replacing the shocks.

I also wouldn't let anyone touch ahc unless they have experience with it. You may end up with more issues then when you started.

Thanks for the confirmation, that's a relief, guess I'll let them ride for a bit and just keep an eye on them. I plan to bring it back to the Lexus Dealership I purchased from for the 100k mile check, so will have them check then.

Alternately clean them up and see how much leakage there is over a defined timeframe. I’m betting almost none.

Personally I wouldn’t even trust a Lexus dealer to touch an AHC system.. oh and lock your glove box and keep the key blade with you! That way they can’t break your recirc flap, if it isn’t broken already.

Haha, the guys at my dealership were pretty laid back and the previous owner brought his car there every 5k miles, so I think I'll trust them for a bit.

Mine leaked for like 30k miles before I replaced them. Just keep an eye on the fluid reservoir. Since none of the actual dampening happens in the AHC shocks, it doesn't really effect performance.

I would recommend replacing the fluid (complete flush) before replacing the shocks. One of the issues that is common on AHC vehicles is a failure to replace the fluid. Over time, air bubbles can get trapped in the system. This can cause a harsh ride, and when the shocks are under stress and the fluid heats, the gas expands, which can cause weeping at the shocks (hydraulic rams). It's worth flushing the system with new AHC fluid, cleaning the shocks with degreaser, and then monitoring if the leaks continue. In my experience the leaks are moderated or eliminated after replacing the fluid and removing trapped air in the lines. If they continue to leak after AHC fluid replacement, then start throwing money at new shocks.
