Question How to adjust steering weight?

I've been fighting some tramlining issues with my e46 for about 6 months. I've replaced all of the control arm and trailing arm bushings with powerflex, replaced the steering coupler and then had it professionally aligned to spec (minus the -1deg of camber I kept).

While it drives straight on flat road - the steering wheel flys all over the place on road crowns and bumps. So I test drove a e93 a few months back thinking I might upgrade - what I loved about it the most was how heavy the steering feels. My Cayenne also has that nice heavy steering. The e46 feels extremely over boosted in comparison - especially when getting it off-center.

I ran across this post: http://www.bimmerforums.co.uk/forum/...-heavy-t55956/

But I can't really find more information about it - or where that nut is even.

Does anyone know more about this? I'd love to stiffen up the steering feel.

Thanks in advance.

I know there was a change in the PS pump at some point in our model run. I have one of the first pumps (original, still) but I believe you might have one that has a superseded pump to correct the issue, so that might be one solution.

Another would be getting an underdrive pulley (a smaller pulley). Don't recall anything about a nut you can tighten...didn't check that link of yours (tl!).

...and it could be your control arms and/or bushings (latter is a very common issue explaining 'going all over the place).

hth...and a bump!

My e30 had e36 rack and I had to adjust the said nut to my liking.
This nut is located on the rack, just above where the the steering shaft crosses the rack. You need 17mm socket and fancy adjustable ratchet to turn it. Adjusting this nut will make the steering either loose or tight, but there is catch. If it is to tight, you steering rack will loose the ability to come back to centre after the turn. Too loose will introduce bump steer. If it is tooo lose your steering will lock (like gear teeth will over run each other).
Try playing with this, see if you like the results. Usually 0.25-0.75 of the full turn is enough to feel the difference.

Awesome - so I just take off the skid plate - get under the steering coupler area - and look up to find this?

Re: How to adjust steering weight?

How are your tires? Enough thread left, and properly balanced?

After changing my coupler, struts and having an alignment my car still had a moving/loose steering wheel. After fitting new tires with roadforce balancing, it was as nice and tight as it should be.
