My dad's new 1991 ix (too many upcoming threads will start this way) has what I believe to be a wheel bearing issue.
In a right hand turn with good sideways force, there is a grinding sound that is audible, and almost physical. Sometimes happens in a straight line, and never in a left hand turn. Classic wheel bearing, aye? But here is something I didn't expect, braking causes the same noise, so does engine braking. And it's just as loud as a turn. A light touch to the accelerator and the noise vanishes. Do wheel bearings fail like this? I thought their noise was purely due to an increased load on the wheel. Thanks for any thoughts! ----------------------------------------------------------------------------------- 1989 - E30 - M20 - Manual. Approximately 270,000 miles 2000 - E46 - M52TUB28 - Manual.

If it is a loose wheel bearing, you can quickly tell by raising that corner of the car and checking for play. Grab the wheel at 12 o'clock and 6 o'clock and see if you can feel any play as you attempt to move the top and bottom hands back and forth.
Usually a bad wheel bearing will make a howling noise and still feel tight so it could also be a stuck caliper. The caliper is supposed to 'float' on the two long bolts that mount it. They often become seized and will cause grinding noises under conditions like you describe. |

Really, a stuck caliper can cause it too? I first thought the noise was the brakes, because it happened while braking and it sounds not too far off from it.I'll give them a 12-6 shake and see what comes of it. I could only remember the spin-and-feel-spring method, which, as you well know, does not work well on an ix ----------------------------------------------------------------------------------- 1989 - E30 - M20 - Manual.
