Morning everyone,

 

Wanting some help with a noise. I have taken the care down to Skoda who cant replicate the noise nor find anything wrong but the noise is doing my head in .....

 

I have attached a video- this is on a normal (ish) road and you can clearly hear a rattle noise.

 

Things that have been checked (apparently)

• Brake
• Brake Pads
• Suspension

 

Any suggestions would be really helpful.

 

Thanks

 

Andrew

Does this noise sound like it’s coming from around the top of the shock area or lower down. 
I ask as it’s hard to make out on my phone, but would remind me of a top strut mount failing.

It’s hard to tell I thought it was towards the bottom but it doesn’t do it over every bump, but when it’s there, you can really hear it. 
 

Would there be an easy way of confirming this? 
 

thanks for your help 

Top mount will be more of a rumbling noise than a knock, knock type noise. Stick your hand at the top of the strut in the engine bay and get someone to turn the steering from side to side. Test both sides and see if you can get a ruff feeling on the side that’s making the noise. If you can jack the car up, you can do the same thing under the wheel arch at top of strut. Watch your fingers. 
sometimes shows as a slight stiffness in the steering as well. 
If a half decent tech hears the noise they will recognise the sound. 
otherwise it’s a bar to check for play in any of the bushes/arms and drop links and hub bearings etc. 
you can check the engine bay and remove the wheel arch liner as well incase an air con pipe or something similar has jumped a clip and is knocking on trim. If you can get help to get a cleaner sound bite recorded it may help, but I’d still be checking the top mount first.

Thank you so much for the help so far. The only other videos I have so far are below. I will try to get a better clip but I am on my own!

 

i don’t think it’s coming from the brake but it does sound like a similar noise but Skoda have checked that.

Start on the lowest bush with Wd40 or similar and see if it changes the noise as you work your way up them, or use a bar to check for play. Just be careful of the rubber boots. 
If you think it’s brakes, put a pull bar or similar on the brake pedal and use the seat to hold it against the pedal to apply pressure to brakes and then try the wheel again

Just tried to get 3 videos - I will post them all separately because of size - first two is moving the steering wheel left to right, there is a clicking noise. The second one is me pressing up and down on the passenger side front wheel

When I press up and down on the car 

Is there any play from the inner tie rod arm on the steering rack. A lot of places just check the vertical movement in the track rod end and not the inner rod itself. If both sides are solid, I still think it’s the top mount that your hearing on the lock to lock video you posted.

I will have a look on the morning as I haven’t got a bar to move it up and down.

 

do you think the top mount would make a rattle noise like on the videos? I would have thought Skoda would have checked that. I have attached another video (sorry using phone holder but you can hear it.
 

thank you for all your advice today it’s really helpful as the noise is doing my head in!! 

The fact that they can’t even hear the noise at all doesn’t give me much faith in them having checked very much at all. 
diagnosing, listening to sound bites is not an exact science unfortunately. Listening to all your clips, they all sound like a top mount, except one! Which sounds nothing like a top mount, but could be the recording sound. Sorry. 
Yes, the top mount will sound like a dull rumble leading to a rattle noise as it gets worse. 
the inner tie rod will knock if you jack the wheel up and check for play by rocking the wheel as it would move when turning. 
All I would do if the vehicle was in front of me is narrow down the location. Check all fittings in that area. Check the bushes, joints and connecting arms. Check the caliper retaining clip to rule out pad hop, or where new pads fitted, check if too loose a fit. Check the shock and spring for breaks or leaks. Check for play in the hub. Check for grinding or knock in the top mount

theres nothing magical about it. It’s annoying as **** most of the time. Can be quite time consuming as well going through everything and then doing it again until you get play or hear the noise.

Managed to get a better video of the noise last night - sent the videos to Skoda but not heard anything back yet
