One simple trick to restore the steering feel of your E46 BMW

So, our E46-chassis BMW M3. Its steering never felt awesome. Let’s call it a little soft, which is a polite way of calling it vague. We could feel a bit of play in the steering before things seemed to engage.

Recently, while backing out of the garage, steering feel suddenly seemed to go from vague to …

The moral of the story is to support the experts that know your chassis as well as specialist vendors and not just rely on random Facebookers for troubleshooting and ebay for parts of unknown origin :)

The real question is - why is there a rubber donut in the steering column? Why not replace it with something without a spring rate? I figured there were probably some aftermarket options and a quick google says I was right: poly, billet or a normal U joint. As an E46 owner, why would I want to use any of these or OE?

That is a very important moral of the story: trusted sources and trusted parts are good.

Condor Speed Shop offers a non-rubber steering U-joint replacement. As the site says, though, track use only.

I’m saving that one for another update.

Similar to a rag joint in the offroad world, where there are kits available to replace them with something solid - not something I would recommend for an offroad vehicle though, as the rag joint has a very slow and forgiving failure mode while its solid replacement may not.

Also newer cars with column-assist EPS have a wearable coupler somewhere between the EPS motor and the steering shaft that can introduce some slop when it wears out.

I'm with Keith on this one, rubber in the steering column just seems like it's inviting slack... no thanks.

It does although I also see how it’s a slow failure rate vs. an instant one.

Hopefully the new one lasts another 20 years.

But if it's not there, it won't fail.

What's the purpose? Is there a change in the angle of the steering column there? I assume not, or the billet ones wouldn't work at all. So why does BMW need a flex joint there? And it seems that steering U joints are a pretty solved problem, so why not one of those?

So many questions :)

Took some hunting, but apparently there's one in my E39 M5 as well. It's only listed on RealOEM as part of the $615 lower column, but that looks serviceable to me.

I always wondered if its somehow a safety thing. For the column to "breakaway" at that point on a front end collision.

On the early e30, without airbag and collapsible column, that's its purpose, I think.

I noticed my e92 M3 went to a solid u-joint, so I purchased one to test when I swap my e46 M3 rack. Been waiting for a month for BMW to ship me the rack, but I will post here whether it works or not.
