Front shock replacement (1 Viewer)

[airforce1]

Hey Mudders,

My passenger front shock is weeping so I plan on replacing both sides shortly.

Will I have to adjust my AHC or reset it after shock replacement? Or is the system smart enough for it to just be plug and play?

Thanks!

Nope. Not unless you mess with the height sensors or alignment. Removing the shock does require undoing at least one of the inner LCA bushings (which is an alignment point) to droop the LCA enough for clearance. If you're careful not to change the alignment, nothing needs to be done. If it does change, you'll want to do a zero point cal for the stability control system, which is not really an AHC adjustment.

Release AHC fluid pressure at the globes, plug and play, and bleed the system after shock replacement. That's it, and pretty straightforward.

If you have any interest in adding weight/armor to the overall vehicle, want to do a sensor lift, or just want added suspension (droop) travel at the front axle to match the rear (@ 10"), this would also be a great time to add the front OEM leveling spacer from the LC.

Thanks @TeCKis300

Actually we will be replacing front shocks and then perform an alignment...we just purchased new tires that replaced older ones that were prematurely worn from poor alignment.

Our rig is currently a mall crawler so no other modifications are on the horizon.

Thanks!

I attempted to swap front shocks without touching the LCA [my tq wrench can't hit the required ## when re-torquing]. Safe to say I was 1/4" of clearance short when trying to pop out the shock from the bottom mount. Called it quits and bolted it all back together - after 5-6 starts the AHC pump kicked in and all was back to normal after a quick bleed. Plan on getting the LX up on the lift this month to knock this out at a buddy's shop.

Feel like the AHC system is way more robust than many think, just don't run the pump dry.

You where almost there! Yeah, the bushings are pretty strong and I couldn't force enough clearance without releasing at least one LCA bolt. For those unlucky enough to be near or close to the rust belt, some have found the bolt to be seized to the LCA bushing... that would be additional suck.

What does your torque wrench go up to? You might be able to project and estimate to the right torque. Many mechanics don't both with torque wrenches and just muscle things on. Though their arms are probably a bit more calibrated and they have a good sense of ballpark torque.

I know, I was following the videos on YT I found:




third due to forum limits:
How to removed & install front shock Absorber Lexus 570#3,

I seemed to have glossed over the part where it took two guys and a breaker bar/piece or rebar to gain clearance without touching the LCA. My breaker bar was 1/2 the length of there's + the front end travel had me SOL. I sucked it up and showered with fast orange afterwards haha.

My tq wrench goes to 180# iirc, and yeah I could probably slap it back together and be fine, but I also just want to put it on the lift and use the big boi ugga dugga.

^Hadn't seen those vids. Good stuff!

As long as the part number is correct it should work, meaning you can sometimes buy lexus parts from a toyota dealer, but I think it depends on their policies.

To answer another potential question, you can't put Landcruiser shocks on a LX570 because of the adjustable suspension that comes on the lexus.

That's what I figured. Looks like the luxury tax on the LXs are for real. Thanks...

Think I was out the door just under 200 a piece. Called in the order to the local Toyota parts counter. Longo and Keyes have the best prices as they use a third party warehouse for parts, their counter will usually get within a few % of those online prices and you don't need to pay for shipping

-edit Don't try getting a Lexus counter (that doesn't have that 3rd party vendor) to match pricing. I got hung up on by a couple of OC Lexus dealers lol

 

[airforce1]

Ugh, I'm in Guam....not many dealers willing to ship out here. No luck with Longo unfortunately.
