2005 F-150 sounds like front wheel bearing is bad. turn to the left and sound is bad. turn to the right and no noise

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.

Sounds like wheel bearing, an easy way to check it out is to just jack up that corner enough to get the weight off the wheel then with one hand on the top and one on the bottom of your tire check for any play. If there is play your bearing is bad. the play will most likely be very very little (less than 1/16 of an inch) but there should none whatsoever. if the grinding noise happens when turning left, check the right side or grinding when turning right check the left side. sometimes the bearing has a bad seal or wasn't properly lubed when being made.

it can be brakes or a wheel bearing

If you hear the nosie when turning right or when turning left? Have you checked your front or back brake pad linings? It sounds like you have a bad bearing,cv axle or ujoint, . Where do you here the noise from? Front or back or left or right?

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?

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.

ok you have a bad right front wheel bearing by what you are describing

the hub bearing is bad.the reason it stops when you turn the wheel to the one side is because its taking presure off the bearing

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).
