isf suspension noise-updated

[hhao]

When I drive my car  on short wavy road, there comes clunky noise from driver's side front suspension, its like shock absorber gone wrong or something else happened.

checked the suspension, no leaking.

only 20000km on car, 2014 model.

Has anyone had the same issue?

 

Cheers

 

 

 

Update:

have the dealer changed the fault shocker, noise is gone, that new shocker ride very well.

dealer should change both front ones for me, but it wont pass thru warranty procedure. now it can be slightly noticed that the old shocker is not as good as the new one when hit bumps. I will changed a kw v3 in few weeks since thats the only best solution in australia.

Noises can be so many things. Even rubber bushes that are sticking make knocking noises.

if you move steering wheel a small amount can you replicate the noise?

If so whilst its doing it get someone to hold their hand around 

1. Ball joint, 2, Sway bar bushes, 3. Rack mounts 4. Shock top and bottom (whilst gently bouncing car) etc.  any knock will be felt in the hand.

If its a bush spray with lanoline or similar.

If its a noise that needs a load try to replicate, try on a speed bump or driveway entry and work out what side.

Does it change if you gently apply brakes? Are wheel nuts tight? Is top suspension mounting tight.......Bounce with hood open and look and listen. etc etc

Might be your muffler bearings, have a look underneath ;)

I have my own mechanic checked every thing underneath, checked the things you mentioned, should not be them.  it comes to the right front suspension shocker.

The noise only comes when road gets short waves, i just dont understand why this noise could happen on a 20000km lexus

Find a road where the suspension clunking noise can usually be heard.

Drive along it, with your foot touching the brakes a little.  Does the noise go away?

Check top and bottom shockie mounts and sway bar link, have you got warranty let us no what happens cheers.

the noise is still there when touching brakes.  the noise comes only below 60km/h, when i drive faster, it is not there.

The car is still under warranty, the first time i went to dealer last month, they said noise issue has only one year warranty and got a mechanic test drive with me around the dealership, he said didnt hear anything.....

Booked for another inspection, hope they hear something. dealing with this kind issue is troublesome and painful.

Have the whole suspension checked by suspension specialist today, they put the car on machine to test the shockers.  the result is that the left front shock scores 62 while the right front  shock scores 23, so the right shocker has a failure inside the tube,by the way,  the bushing rubber etc are all good.  Noticed that the shocker are made by sachs in Spain.

car only runs 20000km, and the shocker is gone, shouldnt happen on a lexus. I will go to dealer with this report, if they dont change it , I will find aftermarket coilover set like bilstein or ohlins, anyone has other suggestions?

[Babalouie]

It should be covered under warranty.  I've had Lexus replace shocks at about 20k when they were faulty before, but in that case the shocks had a visible oil leak

 I went to dealer this morning, they agreed to change the drive side shock.

does your car have only one shocker changed by dealer?

i was told by my friend that its best to change both left and right even if there is only one side gets broken, i asked the dealer to change both front side, but they will only change the bad one.

Wow talk about tight ass Lexus dealer should be changed in pairs pay them for the other shock and see if they get a shock.

haaa, they professionally suggested me to change only one.

i am still thinking change an aftermarket coilover set in  near future, let the dealer do what they should do then, dont want to double spend money.

They changed the pair in my case

thats good for you! i called lexus australia, the guy just told me that the left one is all good , and it will not pass the warranty process to change it.

it will cost $650 for that part and $350 to get it fitted by lexus dealer, btw it come only with one year warranty.

I think spending $1000 to change only one shock does not worth the investment.  I will change the whole set when warranty expires.

$350 to change a shock =$350 hour labour what a joke.

Sadly im not surprised.  Was quoted by Lexus, $1200 to fit headers.  Ok its debatable how long it takes for the install pending who you speak with but several other workshops who quoted me all gave a price indicating its approx $100/hr.  Im sure it wont take 12 hours to fit headers lol.

Wouldnt doubt the quality of workmanship they provide but yes like many manufacturers, they know how to charge.
