Fitted m3 control arms around 2 months ago and poly bushed radius arms but I am now having an issue with a knock from steering rack. Put a new rack on the car around a month ago and knock disappeared but now it's coming back ever so slightly. Mine is a 2011 lci with the electric rack and I am wondering if this might be my issue the electric racks are soft and can't take the harder bushes and arms???

Electric rack or electric assist?

Has far as I'm aware all 3 steering options for E9X (standard, Servotronic and Active steering) are all hydraulic systems.

Unless other markets have something that I haven't heard of yet

Mine has no fluid pipes going to it??

After some quick research it looks like a few models in euro countries got electric steering. learn something every day

I'd post in some euro sub forums as you'll get more bites there; Most countries didnt get anything but hydraulic.

Most LCIs in Europe at least have the fully electric rack; no oil...you're right there, OP.

Knowing what the internals of that rack are like, I wouldn't be surprised if it's not up to the strain of the harder bushings and joints; it'll really be hammered by the impact, where a hydraulic rack would shrug it off. That said, I can't qualify that opinion with anything, so there could well be something else.

What you have said sounds about rite mate. I am tempted to put it all back to standard

Their is a mod on the f series rack where you put a more durable Bush in the rack but know seems to know anything about the e series racks and if their is a mod

Sounds unlikely then... Check on realoem and see if the part number for your rack is used on any F cars?

I bet it's possible for you to transplant in a hydraulic setup though...would doubtless be an absolute mission.

Before you jack it all in, definitely check all joints and bolts in the front end - sway bar too.

I am tempted to just return to standard and call it a day. Some 1 will buy the arms on the forum that has the fluid assisted steering

You're not blown away by the handling improvements of the M3 arms then?

Yeah handling is better but ad rather not have it knocking all the time lol

[Tambohamilton]

Yeah, I bet. Slow cars are better than broken cars!

I'm a bit gutted for you really. I've got m3 arms waiting to go onto mine which I'm pretty excited about - I know I'd not be happy if it doesn't work out! I've got an M3 hydraulic rack lined up for mine too though...

Sure you will be fine having the fluid rack I seem to be the only person that has had this problem. It sucks

[Tambohamilton]

Haha, well if it makes you feel any better I've got a similar problem on the rear of my car, after fitting m3 subframe bushings...

Rear shocks or mounts?

[Tambohamilton]

Nah, it's brake pads or similar. I just haven't had time to sort it out
