Just developing a knock in the steering.
It's very noticeable on the steering wheel, especially when turning either way from the straight ahead position. It's not noticeable when driving - at least, not yet.
My first thought was I was heading for a dreaded EPS failure but there's been no loss of power steering, ever.
Checked the uni joints in the column and there's no play in them. Nor in any other steering components.

So I got under the car with the motor idling and had my wife wiggle the steering wheel (yes, I trust her  ).

I can definitely feel the clunk in the steering rack but I don't know if this is just transference from the column or something loose in the rack.

I'll arrange to get it on a hoist in the next couple of days or so.

Any thoughts in the meantime?

Just rolled over 88,000 klms.

Tested :- no fault found.....

There was a TSB for a knuckle in the steering which used to wear prematurely. Hopefully it is just that, because if so it would be cheapish...

[Surferdude]

Yeah. But it's over 6 years old.

Any chance of finding that Dazz. All I found were some bits about the uni joints which seem fine.

Thanks Steve.  I actually found that on the web, including a similar blow by blow description of removal and replacement.

I'm collating all the info I can before I talk to a specialist I know in Brisbane next week.

I hope it would something easier to fix. Taking the steering column apart can be a pain in the ass (done that few times).

[Surferdude]

I have a friend who has a fairly large steering and suspensions specialist company here in Brisbane.
Last year I discussed EPS with him as he has always reconditioned power steering among other things.
Sent him a note this morning.  He's keen to look at it. 
Ironically,  he's currently in the UK looking at, among other things,  electronic power steering tools and testers. Back in a couple of weeks,  so I'll be sparing in my use of the car till then.
More in due course.

It's not what you know, it's who you know..

Could still be very expensive depending on what they find. But at least I'll know they're honest.

[elantraelite]

I had the exact same problem with my XD Elantra. It was a very common problem and for the whole 5 years it went in under warranty, they used to lube it up and it would go away for a little. Once they actually replace the knuckle and it disappeared for a year or 2, then came back.

Never solved the problem and sold the car when it was 10 years old

Have the same knocking sound in mine when driving on uneven surfaces. Have replaced both drop links and both steering rod ends but can still hear the noise and feel a little slack in the steering. This TSB would likely be the culprit in my case as well.

Could well be.

I don't get it on rough or  uneven surfaces though. Most noticeable at rest or parallel parking.

[Asterix]

Even though the noise really annoys me I'm not in a hurry to get it fixed. I don't think it will create other issues...

[Surferdude]

I left the car with Fulcrum Suspensions last Friday and told them to take as long as they liked to diagnose and fix the problem whilst also doing any other testing and experimentation they wanted.
It's ready.
The problem is my case WAS the little cog as detailed in the above TSB.
The part is inexpensive and probably about 3 or so hours labour to dismantle the column, replace the part, reassemble and reset the computer.
I will go down and pick it up tomorrow.
@Asterix , it could get serious if left too long.
@elantraelite , did your Elantra have electronic power steering? I thought they only came in with the i30. This is more aptly described as a "cog" IMO, rather than a "knuckle" What do you reckon?

Anyway............
Good news.

[Dazzler]

@Surferdude Because it was a TSB it might have been fixable under warranty (even though yours has expired) but obviously can't go that pat now.

What do you reckon, $300 including the part? 

I just re-read this thread (being a mate I guess it might be only half that)

[Surferdude]

Not a warranty issue, Dazz.
And $300 plus the part would be about right.

[Profound_Merc]

Funnily enough i am joining to report this exact issue on my i30 in the last fortnight, a knocking or clunking sound + feel coming from the steering. An 09-10 model but out of the TSB indicted VIN numbers. I just took it to a trusted mechanic and he did an exhaustive test and couldn't find anything. He did say the issue was in the EPS and the knock was coming from just under the dash. He called Hyundai to find out it would cost them $3,600 for a new steering column from Hyundai, without markup + labour. I'm assuming it will be near the $4,500-5,000 mark.

That figure literally made my jaw drop, how can a car thats only 6 years old need such an expensive repair. I've owned he car for the last 5 years and put 98,000 on it in total.

does anyone know if this affects driving or if i should use the car sparingly?

Gulp.

[Surferdude]

You need to find a progressive power steering specialist and show him the TSB above. It's a pretty simple step by step procedure.
But first, read my description above in the first post. If that fits your problem then it's not really a big deal.

[Dazzler]

Like Trevor said, no need to panic just yet. The EPS doesn't usually need replacing unless you completely lose power assist or it starts working erratically  (locking on slightly off centre and needing regular directional corrections)

[Profound_Merc]

To be honest I wasn't panicked until my mechanic told me he took the car across the road to Hyundai and they Electronically tried to (excuse my ignorance) test or reprogram it unsuccessfully and suggested a new steering column. The mechanic was clearly also shocked and Hyundai said they'd only ever done one other one out of warranty because it had been in an accident.

Strange I know, I want to get a second opinion myself as spending $5000 or getting rid of the car are both extreme options.

[Profound_Merc]

... But first, read my description above in the first post. If that fits your problem then it's not really a big deal.

Hey surfer dude did you experience it when driving? My wife normally drives the car and after reading thinks it's worse case than yours. I myself have been driving and felt the clunking in the steering wheel and when turning feel it clunk/click. It's both at low and higher speeds (roundabouts, corners etc.).

I'm looking into a power steering specialist in Sydney now.

Fulcrum tell me the cog was almost non existent. So, prety bad. But I understood other factors come into play at speed so it was almost unnoticeable around town or on the highway.
However, as Dazz says, the only other reported issues have been total failure of the power assist. Which I don't think causes a knocking sound.

[Dazzler]

There are possible cheaper solutions if the EPS does need replacement. A second hand column with a warranty of some sort would be one option. A couple of members have documented repairs done this way for only around half the cost quoted for brand new I think.

Certainly worth a 2nd opinion from a specialist. 

[Profound_Merc]

thanks for the advice, i appreciate you both taking the time to reply. ill try and get a second opinion from a Power steering expert, no idea how to tell if they are a 'progressive' expert but ill give a few places a call, also have the TSB handy. My mechanic is looking into a second hand steering column/EPS as he agreed the brand new wasn't worth it.

I also just thought about it and my wife also noted the 'ESP off' light is intermittent of late, its on some drives, off others. She just randomly told me  now a brake light may not be working. I think the ESP off issue relates to that but ill do some more forum research on that one.

thanks again

[Surferdude]

The brake light issue is a recall,  regardless of age
You'll know if they're progressive the moment you walk into their workshop,  by the condition of their equipment and the way they conduct themselves.
Power steering used to be all hydraulic. Of late manufacturers are going electronic and after market guys are going to have to catch up or stagnate.

[sundiz]

For some reason they do not seem to like service the steering column. They just want to sell the whole column. It has lots of parts, motors, eletronics etc. Therefore the massive price tag.

I guess it might be good idea to ask some shop to manufacture the needed part from high grade polyurethane or some other suitable material. Should not be hard for a machine shop. Using a high grade part the column should last longer than with the oem part.

[panthersteve]

I too have just had a similar problem on my 09 FD however unlike surferdudes problem mine was not evident at a standstill. It was worst at about 40kph, with any bump or irregularity in the road causing what I would describe as a severe clunk. The noises were virtually gone at speeds above 80kph. An initial diagnosis was a problem in the steering shaft or rack.
I took it to my mechanic (not dealer) and he has found the steering yoke (at the floor) had play, he has replaced this and a test drive by me yesterday did not produce any abnormal sounds. It does look like I will need to do the fix as detailed in the above mentioned TSB though as there is a small amount of freeplay in the steering wheel.

Cheers
Steve
