So Scott came by on Friday and we actually managed to swap in the Z3 steering rack fairly easily.

Everything went pretty smoothly and there looked to be barely any binding in the steering knuckle. We didn't have time to actually drive the car that day so it wasn't until Sunday that I actually was able to pull it out of the garage.

Overall I'm pretty happy with the way it's sitting although I seriously need to put my new wheels on!



The problem's started happening when I drove it. I didn't really have an issue with binding so much as the car pulling violently left and right. It fells as if someone is jerking on the steering wheel. I would turn the steering wheel very slightly and then it would continue to turn on its own until it locks

I put the car back in the garage and tried to grind down the steering knuckle but it didn't feel or look like it was binding very much so I wasn't sure how much to really remove. I drove the car again and it didn't feel much better at all.

I'm really not sure what could be causing this. Would a binding steering knuckle cause the car to pull from side to side, because I thought it would make it harder to turn?

I even tried to check if my tie rods were touching my wheel but there seems to be enough room. Power steering has been deleted as well.

Any ideas?

Did you double check alignment? toe out can definitely affect steering. I would lube the shit out of the knuckle and then work it in and drive to see if it changes. I've had binding steering knuckes - typically occurs from car sitting for a while. We use to lube those periodically to keep them free. what tires are you running stock or wider? that can also have an effect. Are you sure the rack is good. A worn shaft can cause binding through it's turn cycle.

Can bad alignment really cause the car to behave like I described? It seems a little extreme.

I guess I can try to make my wheels more even or toe in a little and if that solves the problem then I'll know for sure. I can get a proper alignment when the car is a little more driveable.

By the way the car has stock 14" weaves and the rack is brand new so I'm hoping it's not the rack itself.

Yes, I wouldn't change a rack without doing an alignment after.

I did plan on doing an alignment but I'm kind of scared to drive the car in this condition to go and get one!

I just find it hard to believe that poor alignment can cause this.

I'm wondering if this has something to do with your power steering delete...
How much fluid is in there circulating thought?

I'm starting to think so too.

The rack came pretty much full of fluid and I didn't drain any aside from whatever spilled out when installing the delete.

The problem is that I can't find a definitive answer on how much should be in there.

I PM'd the guy I bought it from on r3v to ask.

You would be shocked how much an out of adjustment alignment can cause the car to pull and jerk violently over broken or uneven pavement. That being said, why oh why did you remove your power steering and buy a brand new rack? That just doesn't compute to me? What am I missing Kevin?

You weren't supposed to drive it until you fixed that toe out! Remember I said "it's toed out, gotta take the wheels off and turn the tie rods in at least two turns each". Yea you do. You really should do that, and remember that the shackles on the tie rods were never tightened either.

I turned them in two turns each, then tightened the clamps, then drove it, then got scared and parked it.

Then I turned them in two more turns each, drove it and no change at all.

I'm going for an alignment tomorrow and new power steering parts will be ordered just in case it's an issue with the delete.

These cars are quite sensitive - believe it or not; if you are in tune with the car you can feel everything and notice the slightest changes. if after the alignment the condition doesn't change- which I can't imagine it wouldn't. Wait ti'll you get wider rims and tires for it and then see what your car will be doing. :-) the proper way to do the alignment on these car is to have the passenger and drivers side weighted to mimic having yourself and a passenger in the car. Bmw used sand bags when doing the alignment. My bmw tech friend use to toe in the tie rods slightly to make the car more responsive (stock rack of course)

Toe in actually gives slower steering response, which is why toe in increases straight line stability. Toe out is what gives you quicker steering response.


One way to really check out what's up with your steering Kevin would be to turn in your tie rods so that you know both wheels are for sure toed in. Then your steering should try and maintain the car in a straight line to some degree. It still might pull right or left, but it shouldn't send your steering wheel to full lock.

I had a similar think happen in my e30 when I swapped the rack years ago, mine was binding in the steering knuckle, Try adjusting it, and give it a cleaning and grease. The rubber rag joint makes it a non solid joint to take up play but it it's worn or not sitting properly can also cause binding to come and go.

Hope it helps and the description makes sense
