My car groans when i turn the wheel, help me diagnose it

Alright, within the last few weeks i have noticed that i get this "groan" when i turn the steering wheel. It's coming from the front, possible the right side. I took it to the stealer for a diagnosis, but they just listed a bunch of parts that it could be and i should replace for the fun it. I know it is not a wheel bearing, which is what they listed (idiots!) But it could be the uppershock mounts, i think. Where are these located, what are the symptoms of them wearing out? where can i get some new ones? Thanx ahead of time.

I think I know exactly what you're talking about. I don't know what the source of the problem is, but my car does the same thing. If I cut the even wheel somewhat hard, it makes like a grunting noise, and sometimes it kinda like "jumps" forward. It's really wierd. My car sucks

What do you mean by groaning? I recently started autocrossing my E36, and i get a winding sound when i turn the wheel. I figured out what was wrong with mine, low power steering/ATF fluid.

Maybe it is something that simple, but i'm not sure you mean by "groan"...

laineyM3 - Two things:

1) Damn we live close to each other! I live in Olney!

2) It's kinda hard to explain the sound. It just makes this wierd noise... kinda like a winding noise. However, there is one thing that goes along with the noise. The idle. The car acts as if I am tapping the gas, because the rpms shoot up a little bit when the wheel is turned hard. So basically, the only noise the car makes is the sound of the engine rising in rpm's. My car must really suck... does this sound like it could be a power steering fluid problem though?

Mike325is, you are right down the street from me! you've prolly seen me driving down GA ave.

Anyways... in your case, may not be power steering fluid (don't you wish it was that easy??) I have no jumps in my rpms, etc. Mine winds casue there is low fluid, so when i'm turning the wheel hard, the fluid sloshes around. Causing the pump to pump nothing... so there is where the wind comes from.

is the jumping feeling like when your car is about to stall?

Mine isnt really a spinnin up sound, it's just a groan like something is being stressed out, but not a scratching sound. My idle sometimes bounces a little when i turn my wheel all the way to one side, but that is almost expected since bimmers have notoriously unstable idles and also the Powersteering pump is being stressed to the max at full rotation. I've checked my fluids, they are all ok. Does anyone have anymore info on the upper shock mounts?

i dont think it would be power steering b/c i can be at a standstill and turn the wheel max each way and it wont do it, only when i pull a fast turn at 30+

sounds like it could be a loose or worn out power steering belt...

I have an unstable idle as well. I think its the idle control value. This is what people have told me on the board. I haven't replaced mine yet but when I do I'll see how the idle is. Try that. Dealing with the steering, I have the same problem I think. When I turn my wheel to the left to make a u turn, there seems to be a grinding noise like the wheels are rubbing against something. Is there anything that could cause this thats fixable or do I just have to live it. Thanks for the help.

Alright, I confess. I didn't read the whole thread. But here are a few comments.

If the power steering fluid is low, it'll groan, make funny noises when turning or if left long enough will cause a loss of PS all together.

If the engine is put under a larger load, a bad PS pump for example it may act strangely trying to keep the car idling when the steering wheel is turned. Especially (even if the pump is good) when at max or near max lock.

I'd recommend staying away for full lock on the steering wheel in any car for more than a few seconds. I try to never reach full lock in my car.

A rubbing noise on earlier 325's can be the wheel rubbing the liner. There was a problem with the stoppers on the rack I think.

So, the reader's digest version.
-Check your PS fluid
-Don't crank the wheel all the way over.

wow this thread is old.

yeah i put PS fluid in my car like a year ago. it fixed the problem. it just so happens that it started happing again a few weeks ago. Turns out there is a slow slow leak in my steering somewhere. It'll get fixed someday.

also i noticed that if i do turn alll the way to either side, the tires will rub. i never crank the wheel all the way over after hearing that rub the first time. i dont even need to. these cars have a great turning radius.

wow, yeah it's OLD!

I just saw that too!

Anyways, the leak is more than likely the hose that runs down to the rack. It's pretty low on the left side. I think you'll see some fluid at the end of it.
