Long time lurker.... first time poster.
I recently joined the club and got a 2005 Grande V6 with 175K on the clock.
Was a city car only, but for me it will be an off-road vehicle mostly.
Suspension needs replacing.
Airbags seems to be leaking as the compressor goes every morning AND it ends op on the bump stops during rough terrain which really make for unnerving handling going downhill etc.
Lots of body roll as well so guessing the shocks are done for...even though they seems to respond to the ride settings and there are no leaks.
So.....
Getting original Toyota TEMS shock doesn't seem to be an option with partsouq not having stock for both front and rear plus quite expensive too.
I have read heaps of the suspension post and I cannot recall a single post mentioning the KYB OE replacement parts to replace the TEMS.
They are electronically adjustable shocks made to be an OE replacement.
7410000
7440002
Automotive Superstore ~$1644
Sparesbox ~$1830
Partouq $857 delivered
Edit: above price was updated from first post, I thought the store was selling them in pairs but they just had crazy prices for 1...lol.
Partsouq also did not have stock when I was buying, they have plenty now, so you may need to wait and things change
Surprisingly I was able to buy the TEMS shocks directly from Toyota for A$932 all up! happiness...
A local fitter, Garage76 in Canberra, was quite firm in his opinion that I would better off by getting some custom Bilstein's that has been valved to match the Airbags.
He claims he has "been down this road".... now unfortunately they are quite busy so I didn't feel like asking him to explain further.
Now I have a custom Bilstein suspension in my modified 3.0R outback... it's very nice. I'm sure the Bilstein's would be great in the Prado as well.
But I just cannot see how standard shocks that does not have electronic semi-active adjustment could deal as well with different situations as the TEMS...unless TEMS really are just rubbish.
Excerpt from presser.
There are a few unknowns to me..... letterboxman amts schnitzelburger Whitey
1. Would new TEMS shocks really make a huge difference over my 180k shocks..... some posts here has suggested that it does.
2. Would the KYB be equivalent to the Toyota TEMS....KYB claims so after speaking to them on the phone.
3. Is the TEMS really just a gimmick and a custom valved Bilstein would just overall perform better..... as my local installer claims.
I don't intend to do a lift.
If I do change the front coils I would be after 20mm only to end up around 760mm at the front and 790-800mm rear.
The accessories I intend to fit in front will be most likely an ECB alloy bar ( adds 27kg ), winch ( ~24Kg ) and bash plates.
Now it could be that adding that extra weight and then fitting a different springrate coil in the front would necessitate fitting appropriately valve struts.... or would OE still be fine...

Excerpt from presser.
The TEMS hardware includes two-stage dampers, with soft and hard damping force valves.
There are nine different control modes in the second-generation TEMS system.
Non-linear H infinity control: changes the damping force to a target value according to the road surface and driving conditions.
Thumping sensitive control: prevents an increase in damping force when (smooth) road conditions mean no damping force is required.
Unsprung vibration control: if unsprung resonance is detected, this function controls damping force so it will not decrease below a certain level.
Imaginary roll damper control: changes damping force to control vehicle posture (minimize body roll) during cornering.
Anti-dive control: increases damping force during braking to optimize stability and controllability.
Anti-squat control: increases damping force during acceleration to minimize changes in body posture.
High-speed control: varies the range of damping force according to vehicle speed, to provide the best combination of comfortable ride and driving stability.
