Scraping Steering Column Sign In

2010 Hyundai Elantra Touring

My steering column sounds like this (only the first 10 seconds are pertinent):

https://youtu.be/OfgFWKnVStY?t=32

Note: this is not my video, but the sound is identical to what my column is making. The person in the video resolved his scraping by replacing the steering rack. I put my head right at the knuckle, though, well above where it goes into the rack and I'm practically certain the noise is coming from the power steering motor area- or higher.

Some background. I just got finished replacing the steering coupler. At first, I thought I had cleaned the housing too aggressively, and that's what rubbing (it could be plastic against plastic), but... I've watched videos on how these steering motors work, and it's done with a gear, so the movement, when compared to the steering wheel motion, isn't 1 to 1. When I move the wheel, whatever scraping I'm doing is occurring at the identical rate of my rotation- not faster, not slower, not delayed. It feels like it's inside the column housing, an area that I didn't access during my coupler repair.

Re: Scraping Steering Column Sign In

You just had the column apart so I would be looking for something making contact inside the column. Sometimes it's just the covers rubbing.

I thought that maybe wiring could be in the way, so I went up and down the column with a fine toothed comb. As far as I can tell, other than the steering wheel itself, and the very small section down by the knuckle (and, obviously, below the knuckle), no moving parts of the steering column are exposed.

And I had the EPS motor apart, and the column separated from the vehicle, but I never accessed the inside of the column where the scraping seems to be coming from.

I was thinking about this last night. If the column is a moving rod inside a stationary pipe cover, it feels like whatever lubricant between the two is missing.

I handled the steering quite a few different ways while working with it. Not roughly, just grabbing it by various points. Could that have impacted it?

Re: Scraping Steering Column Sign In

Look closely at the plastic at the base of the steering wheel. It can be as simple as the plastic contacting the base of the steering wheel.

Other than that you are just going to have to follow the noise to it's source. Have a helper keep moving the wheel to produce the noise while you follow up and down the column listening to pinpoint the noise location

Re: Scraping Steering Column Sign In

As it turns out, I'm about 85% certain it's a bad worm shaft bearing. The bearing is defective on 2018 and newer hyundais, and, although mine's a 2010, the sound matches up.

Thanks for your help.

Re: Scraping Steering Column Sign In

It looks like I'm going to be taking apart my worm shaft (the shaft that transfers rotation from the eps motor to the column) because of what I'm relatively certain is a bad bearing and there's a good chance I'll need to replace the grease that's there.

In Hyundai TSBs for newer models, they show a picture of 'kluebersynth le 44-31' grease. I googled it, I can't buy this grease. And, although the dealer might have something, I'm looking for an alternative that can ship faster- and, hopefully be less costly.

On the product page it says:

Quote
Kl├╝bersynth LE 44-31 shows particularly low friction coefficients at high percentages of sliding friction for steel/plastic combinations. Tests were conducted with all combinations of known grease components with the aim of determining the one with the lowest friction coefficient, which is now available as Kl├╝bersynth LE 44-31.

So, it's a steel shaft against a plastic gear. Because of the plastic, I'm assuming petroleum based isn't a good idea.

Any recommendations on what I might use?

Note: my hyundai is from 2010. No warranty, no recall. Newer models have either a shaft or a bearing kit that includes the grease. No kit for me.

Re: Scraping Steering Column Sign In

I don't know what you are trying to do here.

The noise if the video you provided which wasn't even the same make of car, didn't sound anything like a bearing.

The piece you are referring to I believe is sold as part of the steering column and not serviced separately.

Re: Scraping Steering Column Sign In

Here's the noise on my make (different year, but my issue)

https://youtu.be/cvogIlCCntE?t=4

I brought the column to my bench, and narrowed down the sound to the eps worm shaft- specifically the bottom bearing- this is the bearing that fails in the newer models. You are correct that the worm shaft/bearing isn't sold separately, but the entire column is about $2K new, $1K used. If I can get to that bearing, I can replace it with a $10 bearing. I'm still figuring out how to get to that bearing (the cover is crimped into place), but that's the eventual goal.

Right now, though, I have a new issue that relates to the same column removal/coupler replace job, so I'm putting it here.

I decided to, for now, live with the slight wooshing noise of the bearing and put the column back together. The last step was putting the top and bottom steering column covers (aka shrouds) back on. When I try to put the top cover on, there's no space for it. Here's where a larger gap should be:

And here's the cover that I tried to jam into place.

https://imgur.com/oILWACL

The notch is supposed to line up with the square turn signal casing. Not even close. As I said, I took the column out, I held onto parts in the middle of the column to carry it, I worked inside the EPS motor, but I have no idea how the steering shaft could have been pressed into the rest of the column. It makes zero sense.

Any ideas as to what's going on here?

Re: Scraping Steering Column Sign In

The more you mess with it, the worse you are making it. You're going to end up destroying the column and having to buy one anyway.
