whats the grinding noise in front end.
sounds like you are losing a front wheel bearing, unless it changes when you hit the brakes and then it would be a brake problem likely
or a shaft is on its way
i took off the barring on the one side... there was just 1/16 of little play in it, is that enough to make such an loud noise? I hope its not somthing to do with a differential barring or somthing. How can you tell. theres no play in it, I had it up to 80 mph and it was fine, just loud. shafts seem tight
I have had wheel bearing with no play roar really loud. wheel bearing will tend to change its tone on turns. It will get louder turning one way and quieter turning the other way. If it does not change you may have to raise the vehicle securely and run the vehicle in 4 wheel drive to try to pinpoint the noise. Good luck!
Check your differential fluid/transfer case fluid. Make sure they have been changed regularly. Is the noise present in 2WD (if you have selectrac)
