GRINDING NOISE FROM FRONT WHEEL My BMW 325ti Compact makes a grinding noise when there is load on the front wheels especially on left turns. Repairers have tried to fix by replacing the fluid but this has not worked. Dont think it is the pump because noise does not occur while turning the wheel whilst stationary. Also I have noticed the noise goes away as soon as my left foot touches the brake even while still on power (that may give extra clue)

This due to either a worn wheel bearing or a worn front drive arm.

The most common cause of a grinding noise when turning is a worn front wheel bearing. What happens is that the weight of the car is shifted on to that wheel as you make the turn causing the worn bearing to make a grinding noise.

pads may be warn down and grinding on the discs.

check for failed wheel bearings or loose wheel on studs. Check suspension ball joints and steering joints the problem is serious so have the front inspected by a competent mechanic

Check front tyres & wheel bearings espesially the R/H/F. Feel tyre for high / low spots on inside & jack up & spin wheel if you get noise while jacked up it is not the tyres but wheel bearing or brake pads but more than likly a crook bearing by the sound of it. It needs to be tended to ASAP

Does sound stop when you turn LEFT?

Turning RIGHT puts the heavy load on the LEFT front wheel.
That initially STOPPED the noise, correct? So why did you change L?

Turning LEFT puts the load on the RIGHT. Did you change the RIGHT?

Let's say this:
If turning RIGHT stops the noise, it's the RIGHT one that's likely bad.
If turning LEFT stops the noise, it's the LEFT one that's more likely bad.

Make sense? Turning RIGHT loads the LEFT wheel; and vice-versa as the WEIGHT SHIFTS AWAY FROM THE TURN.

More than likely it is what some folks call a CV joint problem, not wheel bearings. Try backing up and then going forward to see if "clunking sound" or a sharp "bang" is heard. Wheel bearings and CV joints only work if smooth. Sometimes a BEARING RACE is bad. Also, a bad spindle / part of the CV joint / transaxle assembly worn or badly machined. If in a WET ENVIRONMENT especially, u may want to try marine grade grease or teflon-added grease.




Does sound come from POWER STEERING PUMP area?

when turning left vehicle distributes weight to right front wheel bearing causing load. since u describe a noise in right front while driving straight i would suspect failed right front wheel bearing. see if your noise changes/goes away while turning right that should tell u 4 sure

You should definitely pull the front wheel and check the bearings (they are roller bearings, not ball bearings). With the wheel off, you should be able to isolate where the noise is coming from, but I vote for the bearings. Check, replace and/or repack, and adjust properly. If you have noise, you should be able to feel the "play" in the bearings, or see the wear problem on the spindle and bearings. I hope this helps you.

Just had the same problem left front wheel bearing was gone in mine hope this helps should get it looked at rite away front wheel will seize and cause a lot of other damage

grinding on front wheel is caused by 2 things. a bad or loose wheel bearing,or worn out brakes, have them both checked
You might also want to check the level of fluid in the power steering reservoir - low or lack of fluid will also cause a noise (although more of a whining than a grinding).
