This is driving me crazy for about the past 4k miles, when I pull out of the driveway and turn the wheel, or any time that I turn the wheel at crawl speed, I get this whole car-body groan from somewhere in the front half of the car. I have greased everything under the front end that I can find to grease with a hypo-needle-type grease fitting and no improvement. Over these last 4k miles it has not gotten worse so I'm not freaking out yet but it sure is a big ?. I have tried to find it from underneath while having someone behind the wheel do the turning but the groan travels and it sounds like it comes from everywhere. Can it be a body bushing or something not belonging to the ball joint-tie rod-idler arm family of normal suspension parts which I have already lubed??

No grease fittings, right? You can't get the grease where you need it with a needle. Could easily be the dreaded dry ball joints.

Yup, no grease fittings...but the rubbers took at least some pressure from the grease gun...no good?

It can do some good to put some grease on the outside of the fitting (under the boot), but you won't get much inside, if any, with weight on the joint. The parts sit very tightly under the pressure of the suspension.

it will take but a minute. do a visual inspection of the engine mounts. i had a similiar situation. god, was it obvious that the mounts needed attention.

Check the fluid level in the power steering reservoir. When it gets low the pump starts trying to pump air and bubbles and this makes a groaning noise when you turn the wheel.
