When you say that thread do you mean this one?

Probably the one he gave you a direct link to.

Just wanted to update this thread for future reference. After fitting in the m3 rack with a new ps pump, ps fluid reservoir and pulley the handling is amazing at slow and fast speeds. The car handles how it was suppose to handle from birth. No more slowing down on turns. the servotronic is def not needed imo.

I absolutely love how it transformed my 335i.

I'll be parting out the entire car in the coming month or so. M3 steering rack will be up for sale soon if anyone's interested!

What year is your 335?

What parts did you exactly use? M3/1M hydraulic pump and pulley?

Bmw pulley and oem ps pump, regular 335i parts. The m3 pump is overkill and not needed. If you get a new reservoir as well which you should don't forget to pick up a new set of hose clamps which are one time use as well as the bolts on the pump.

[juld0zer]

Was there something wrong with your pump before? I dont quite understand how everyone complains about very heavy low speed steering yet you fitted a new 335i hydraulic pump, pulley and reservoir and it feels good without enabling servotronic.

Ive only replaced pumps which were leaky and pulleys which were chipped from hitting the subframe. Neither scenario resulted in any change in steering feel

When turning the wheel full lock left or right I would hear a slight rubbing sound, kind of like if my front tire was rubbing on the inner fender. My car always made that sound which I thought was normal but realized it was not once I fitted in a new pump. Now turning my wheel fully left all the way or right I have no sound what so ever. Maybe these guys are just replacing the rack and not the pump as well which is why they almost feel like the steering is broken or to stiff. I read through some post on diff forums it seems other people state exactly what I said that the steering was perfect after the install and you have some others that complain about stiffness. I wish you could drive my car so you can see what I mean. Those who complain about the stiffness might need to exercise a bit lol. Mind you my parking space in my garage is at a tight angle so I have to move the steering wheel a lot to adjust to squeeze in at very slow speeds, and while yes the steering is def tighter and harder to turn it is def not unbearable or unmanageable at all what so ever.

Awesome that the new PS pump and PS resevoir helped.
Can you link these to these products/part numbers i want to see if they are different PN on 1 series. I would definately prefer not to do the servotronic retrofit & coding

Here's the p/n for the ps pump 32416779244
Here's the p/n for the pulley 32427553955

The pump is the same pump that comes on the 135 and the pulley also. Ecs list the same pulley used for the 1m.

Thx. I noticed that the x35i get one type of pump while other engines get another PN.
Some of the first steering rack swaps were one on 130i and 135i and maybe the 130i impressions created a bias as to how stiff the stering feel becomes.

That might be the case. But I've read a couple of guys on n54tech claim that it is to stiff as well.

Hi guys,

I am trying to center the M3 steering rack but it seems strange.

So I used the black arrow to line with the two markers on the rack. However, if I do an end-to-end turn, I don't get even turns on either side.

The "center" of the rack is shown in lining the black arrow to the green line below, right of the bolt that attaches to the heat shield.

Is this correct? Thanks!!!

The plastic tab/cover won't spin on the spine?

[bbnks2]

Where did you find that the "arrow" is supposed to point to that spot?

Personally, I found dead center of the rack and marked it on the rack/black cap. I then connected the rack to the splined steering shaft and rechecked to ensure the rack lined up with the splines while still at dead center. The result is that I have the same lock-to-lock distance in either direction. I did not line the rack up to any writing from what I remember and the shaft would not connect in the position I wanted it to without breaking off the alignment tab (135i specific).

The plastic and black arrow does spin with the spline.

Just thought that a marking would be a convenient way for an installer to put it at center.

Okay - that sounds good. I'll just use the lock-to-lock method, which seems a lot more correct than aligning to the markings.

Since the tab will be removed, also any suggestions on how to align it perfectly steering column/keeping the steering wheel straight? It is quite hard to shove the steering rack into the steering column, which may cause some slight unwanted rotation.

[bbnks2]

I'm sure you won't notice if the spline ends up being off 1-2 teeth... Put the rack up into the car while it's at center. Use that arrow and some kind of marking to ensure you stay centered when connecting.

[juld0zer]

Use an assistant to hold the wheel straight.
At work i nick the wheel alignment wheel holder
