Creaking and groaning suspension : non active suspension

My car is going in for a routine service soon and I want to get them to look at the creaking suspension.

 

There is a lot to digest in this thread but the summary seems to be that the following is the solution:

 

Replace anti-roll bar bolts with modified design.

Grease wishbone bushings with lithium grease.

 

Has the above generally worked for people?

 

I believe the bolts have to be changed when they are removed. They usually grease the anti roll bar bushes, but they have changed the type of grease they use (I was told they now use a lithium grease) and then fit the new bolts. That has been done on mine twice now, but the last time it was in they have changed the wishbones (and in doing so have new bushes in them). It may be that lithium grease would be adeqaute.

You are correct in that the thread is for none active suspension. However, after reading the thread the symptoms people were describing were the same as on mine. I have an L&K so have an active suspension. I don't know the full workings of an active suspension, but I believe it is within the damper and that roll bars and wishbones may be common components between active and none active suspension.

There is a thread specifically for a knocking with the active. Worth a read for you active boys.

Actually the Active and Non-active use the same components (these that create noise). The only difference are dampers. So having two threads makes no sense. Bushings, Anti-roll bars, wishbones that's all the same. Noise comes from those not the dampers.

It's same issue. The only difference in Active/Non-active suspension noise was rear hydraulic bushings which created slight "knocking sound". Front groaning and "squeaky" suspension noises come from wishbones basically the bushings material. In theory aftermarket bushings can fix the issue permanently. But they need to be "stiffer" hance the car would defo feel a bit stiffer. I can guarantee this because I've replaced bushings on my Superb twice including rear hydraulic ones and I also fixed the issue permanently on my mothers Octavia (with exactly the same issue, as its over whole VW group, Passat, Golf, Superb and Octavia, maybe even further, but those I can confirm) by replacing original VW bushings with harder aftermarket ones, suggested by my non-OEM mechanic. 

This issue can also be solved by special grease which VW/Skoda dealers usually apply. In my case on Superb they applied it very very heavily after 2nd bushings were replaced. That solved the issue for a year (then I sold the car). I watched each work there in the shop, because I wanted to see how they're repairing my car. I'm one of those people who does not trust other mechanics and I also love knowing how all this works/is done.

Lubed up again... Wonder how much this yearly ( ish ) procedure is going to cost out of warranty ...

Might be worth investing in poly anti roll bar bushes (they aren't that expensive) and do away with the rubber ones (assuming they are rubber and not poly bushes already).

Yeah I'll have a suspension refresh. I think they are just using crap parts.

[Steviedakota]

Car was serviced today, asked them to lube the wishbone bushings. Service manager said there is only so much they can without removing them, and that this creaking is endemic in VAG suspension and brand new Superbs are just the same. The creaking is going for now.

Hi, I have a superb combi 2011 and I have trouble crouching over the cops in the front of the vehicle - shock absorbers, ... I was changing the stabilizer, selenium tires, .... but squicking stay. Maybe it's a problem in shock absorbers and bumbers, Is enebody changing them for that problem resolving?

So... something new to resolve this problem ?

Mine also started knicking/rattle in front at just 2000 km.

There will never be "new" solution to this problem. VW/Skoda use very soft bushings which due to their material create noise. When greased with special grease they quiet down. Replacing them with harder bushes is the solution, but you will feel bumps more and its aftermarket thing. Warranty should not be affected.

Our 2016 MKIII has the same creak/groan problem feature. The car is booked in for warranty work on the 1st July so I’ll have this looked at too. Interestingly, our MKII had exactly the same feature, which was caused by the front anti-roll bar bushes too. They were replaced with poly bushes and the noise never returned.

Touch wood .... Mine are STILL !! Ok ... Like you though I'm expecting to have to change them at some point ..

Thank for the summary.

I have a Superb MK3 2017 4X4 with these squeaking noises front the front side. During the annual service I asked the dealership to check this issue. They claimed they put lots of grease, but the noises haven't changed at all.

I'd liked to lube the wishbone bushings as it's out of warranty, and was advised to use this specific lithium grease and not any type of grease with code G052150 A2

Since it's out of warranty, I'd like to try this myself.

 

Does anyone have a photo of which specific bushings are the cause of the noise? Do I have to release the bolts to apply the grease?

 

Thanks in advance.

This is (presumably) an official document from Skoda explaining how to use the above lithium grease to fix the noises. 

Is there a place where I can find pictures of these transverse links so I can apply this grease? 

Thanks

I wanted to share my experience of the emissions warning light as reading these forums I could not find my issue. 

I have a late 2015 Superb Business 2.0, Always Skoda serviced. Currently, with 68k on the clock and only serviced last month. 

 

Driving to work I get the warning light appear. I pull over. Switch off, wait, restart, still there. So I continue my journey to work. Check these forums but none the wiser. On the way home the light stays on again. So a quick call to Skoda Winchester. They advise a check. £100 to diagnose, then additional charges.

 

I also tried an independent who specialised in Skoda, Audi, VW and Seat.  Their cost £25 diagnostics. So I drove there. 10 minutes later and the diagnostics identified one fault, and this was due to a fault with number 1 glow plug. Without bothering to check with a Skoda dealer, I trusted this small independent to carry out the work. Cost £87 and collected the next day. 

 

The advice I was given was, glow plugs can develop a fault at any time. There are 4 plugs, 3 are the same and cheaper to purchase, however one is the main glow plug that is more expensive to replace, due to higher purchase price.(luckily for me this one did not fail)

 

So...68k and only one failed glow plug. I've had the car since 28k and that's my only fault out of warranty. Ran to work this morning and no engine warning lights on. So for me, problem fixed. 

 

Anyone else had glow plug faults?  Was this a good price to fix? Should glow plugs fail at all?

 

 

 

 

Good price? Most of it was labour.

 

If you've got a hot engine and have plus gassed a couple of days before glowplugs are very easy to change with a long reach socket on a 1/4 inch drive with extension.

 

I've never heard of a different glow plug for a single cylinder, even on early DPF equipped vehicles, they typically had a 5th injector on 4 cylinders.

 

The plugs are standard Bosch Plugs universal across a lot of engines within and outside of the VAG Group.

 

A set of Bosch Duraterm Glow plugs is anywhere from £25-50 for 4 dependant on where you source them.

 

So if they've only changed one, bit of a rip off.

Probably not have much interest on a thread about noisy suspension !!

[paul_7_7_7]

Got this problem on my 67 plate Sportline280. The bushings being discussed, are they the mount bushing to part 1, or the bushings at the ends of part 4?

 

thanks

It seems that you have to complain at least 4 times before Skoda actually do anything with a warranty issue. My old Yeti 1.2tsi sounded awful occasionally on start up........on the forth time of complaining they changed the timing chain. My 2 year old superb estate makes awful creaking and groaning noises at low speeds....and independent garage said that the anti roll bar bushes seem to be detaching from the car! 😬 Skoda decided on the second visit that covering the car with grease would solve the problem.......on a nearly new car, the other garage thought that was completely unprofessional.........so on the forth visit when i was prepared for a war they admitted that there was excessive play in the roll bar.......did i want to pay for it to be changed 🤪 a quick visit to pick up my car they  said they would do it under warranty.......at times it seems Skoda forget that once they have sold a car the customer might buy another.....not with an attitude like this. It seems that unless you stick with it they will deny most warranty issues...............................
