Front AHC Shock Leak

[benn]

Unfortunately it wasn’t apparent where the leak was coming from.

I am confident the shock mount horn was dry above (should have ruled out the o-ring), and the leak/wet was originating at the top of the shock body between the shock and the frame, while installed. The old o-ring was in great shape, I put it next to my new one and couldn’t tell the difference.

But the old shock after cleaning up looks great. I’m not sure, other than something got fixed since it isn’t leaking now. Would be interesting to put this old shock under pressure somehow and see if it leaks from a seam around the top.



Thanks again.

Could be a worn O-ring. I wouldn't expect a worn O-ring to look visibly bad so that's my guess here if that shaft looks good. Either way, great pictures. Thanks for sharing!

Enjoy the new ride.

I just did this on my '04 this week. Noticed AHC fluid leak under driver's side front. Researched a ton on here and narrowed down to O Ring or corroded top of "shock". I quickly found the culprit after I removed the shock. Some AHC fluid shot out at angle that it shouldn't.

Yours looks very similar to mine. I dried mine off and sat it on my workbench while I cleaned up the shock tower and frame. You can see where I have a small pinhole leak.

I also changed out all 4 globes.

Why does that piece look like a dog gnawed on it?

It corrodes under the rubber cushions.

Awesome work man. Nice find on the leak and picture to show.

You're right, the shock isn't $400, paid $242 for the shock, ($204 from McGeorge) but for everything it was right around $400.
Here is what I ended up going with from Lexus of Oxnard Parts. Slightly more expensive than McGeorge (now Ourisman Toyota of Richmond Parts) but Oxnard is offering free shipping so total cost is about the same. May not have needed some of the hardware, got multiples of some of the seals/cusions but figured it was good insurance to have everything on hand once it is apart. Thanks again for all the feedback everyone.

Hey Man, running into needing to replace the front shock absorber on my LX

Did this parts list work out good for you? I can find everything on IMPEX except 9008011232 - The bracket stabilizer bolts. Also, was 9671119009 Fuel Injection Idle Air Control Valve Gasket for another project? Doesnt seem like that goes with the front shock absorber parts?
