same problem here, already replace upper and lower ball joints, control arms, sway bar links, both spindles and clunking still there, but less or none when raised, so now iam thinking of replacing the air struts, i did buy the car used and it has arnotts already installed, is it possible for them to make the noise.

thanks

Arnott shocks

So when you replaced the shocks what was wrong with them? I had a bad arnott shock but did not have the clunking noise, had the strut replaced under warranty and now I have the noise . definitely annoying! I'll seee whatb my mechanic says.

My car is starting to do this. It is the steering rack itself. The slide bushings are getting play in them. Very loud for a very small amount of play.

Did you end up solving this problem? Just replaced my front right strut with an Arnott and I now have this issue.

No, I have the engine torn apart at the moment, then it's getting put up for the winter.

The clunking noise may be the airmatic pump rattling. I had this problem for years until a mechanic finally figured out what was wrong.

The solution was to replace the bracket holding the airmatic pump, and install some thick washers on the spring posts that hold the pump in place (there was still some play even after replacing the bracket and springs, and the washers tightened it up). You may be able to fix it by just adding thick washers to the spring posts. Take off the driver side fender liner and you can inspect the airmatic pump to see how much play it has in the bracket.

Mine has only clunked once on the left side after a beat down session in the mountains this weekend. I drive with the radio off and hear every creak, groan, tink and thunk.

The noise I heard was turning hard to left stopped.

. It feels weak like the PS pump cannot keep up. I have a leaking rack from a previous owners neglect, that may be losing more with the force of the turn while stopped, maybe losing pressure. But that does not explain the chunk...?

It is only on the left side...?

To fix I figured at 123k it needs a refurb. So my list will start with C Arms, L. ball joints and upgrade my 2004 to a 2006 E55 rack.

I would love some poly bushings to firm stuff up, but if OEM last 125k miles why jack around with their engineering much... Love a Guru's info on if there are Poly-bush upgrades someone has found that work?

I drive in the mountains a bunch and this sloppiness is not cutting it, time to make her drive newish again... Or think about coil's again :-/

Convince me to fix stock please :-)

My car started making the popping noise right after I replaced front shocks with Arnott units. I am still uncertain where the noise originates. I do need sway bar connecting pieces replaced at least.

No, the upper part of the strut bolts directly on to the body with 3 12mm nuts on to bolts coming from the strut top. The air pressure pipe connects to the center from the engine bay side. It does not have a bearing or gap. The rotation of the lower part of the strut is handled internally in the strut body somewhere. Since I noticed the same popping for the very first time, right after installing arnott struts, I wonder if it is typical to Arnott. (I still have not solved or really devoted dedicated time to it. I need to use the body shop equip with microphones strapped to various components and get to the root of this issue.

у меня была похожая ситуация , долго искал причину шума , в итоге оказалось - передний стабилизатор поперечной устойчивости...

check ur torque arm bolts. Mine was loose causing a similar sound. Didn’t realize until I replaced a lot unnecessary parts.

Shortly after I replaced 2 Arnott air struts and 2 Arnott air bag, I started to hear the loud clunking noise in the front and some in the rear as well. So I replaced the upper and lower control arms in the front but the noise is still there. The mechanic checked the sway bar end links and didn't see anything wrong. I don't know what else to replace. Could it the Arnotts that making the clunking noise???

Captive nuts in the chassis for rear suspension subframe like to tear up the body. I got to cut holes in the car... Make up thick plates with nuts welded to them and weld it all in place. Front suspension subframe will make clunks. Tighten it up. As mentioned above... Control arms with balljoints. Seems like when one dies it makes more sense to do all of them in one end of the car or the other. I have had balljoints that were quiet until pulling an air strut... Then very noisy balljoints.

See if if you can easily slide fingers between the oil pan and the front sway bar. If not; it is time for engine mounts.... Again.

I don''t know how to do this so I forwarded this to my mechanic. He checked what you have mentioned here and said mine was okay. I don't know why the clunk noice is till there.

Struts are able to clunk too. If your tech can't find the sources of noises take it to someone who has 'chassis ears' (a special tool) so that multiple microphones can be attached to likely sources of clunks.... As the noise happens the mic with the most noise wins. Dealerships are most likely to have this tool. Expect to pay for the effort it takes.

All the sudden, the noise has stopped for the last couple days. I am too happy to try it on the raised position or sport/sport+ modes. Will try all the combinations today. I now believe that the clunck are coming from the struts. Other than making those noise, the Arnott struts seem to function well. I don't know if it works the effort to contact the seller because Arnott struts are lifetime warranty. The cost of uninstall, reinstall, shipping, and rental are too much to handle.
