Hi, I have a 2000 4.6L 4x4 F-150 with 150000 miles on it lately it has been making a loud grinding noise when I take a sharp left, to the right its fine. I also have been noticing sparratic whining noises that come and go without notice. I had the 4x4 ujoints changed a few weeks ago. Also the truck is making clunks when you go over rougher terrain such as our cornfields or even when you must take a sharp turn on a steep incline. Probably time for a new truck but funds dont allow it yet. Any help would be greatly appreciated.
Thanks Alot
Ps. Im not sure were I was supposed to post this.

 

Check your sway bar links.. My clunked like that

 

Actually my buddy also mentioned that, thanks will do

 

If not the sway bar, may be a front bearing for the grinding noise. You would normally feel it in the steering wheel.

 

Actually I cant feel anything in the steering wheel thats what got me puzzled, Just a few more hours and I get out of class so I can check these things...Thanks for the suggestions.

 

Well just found out I need to replace the hub assemble, jacked the tire up and it rocks pretty good.
