So i have encountered a problem(s) with my 97 7.3 f250 recently i started to have a grinding sound as well as vibration along with it in the front left area of my truck only when turning right above about 20 mph with hubs unlocked (have not tried with hubs locked), the grinding will get gradually louder the more sharp the turn is. Also when braking from higher speeds there is a gradual grinding and vibrating from the same area not as loud as the turn though. There is movement in the axle going back and forth about 1/4-1/2 inch only on the drivers side and still does it when the hub is locked so i believe this is also a direct relation to the grinding. I believe it may be both inner and outer bearings are shot (or getting there) and/or the spindle bearing may be going out but i'm not entire sure on what it is. There are no leaks so i don't think any seals are broken with the axle movement. If you have any knowledge on the subject any help would be appreciated before i take it apart this upcoming weekend.

 

So i took apart the hub, took the rotor off and replaced both inner and outer bearings but it did not fix the grinding noise so it is in direct correlation with the spindle itself next weekend i will take off the spindle and find out exactly whats wrong with it. There was play in the spindle both moving in and out and around after i took the rotor and the hub off so maybe a type of seal is broken? or the spindle itself is worn and i need a new one but i will find out and post hwat was wrong after i fix it this upcoming weekend. i may even make an instructional video of how to take all of this apart because i have found none for my year and make for my truck.

 

Can you elaborate better on the axle shaft movement?
