Great vehicle.

Recently did a Tranny filter and tranny cable change. (aw4)

Took it on a long drive. Made it fine, no problems, although running a little hot (it was hot out too). At the end of the drive I got into town, slowed down, and on slow left turns I heard a bad grinding sound, coming from under me and just to the right I think. I also heard it going straight and right but mostly left.

Changed a wheel bearing, u-joint, checked the others, removed the front driveshaft. Figured I was good. Drove home (6 hours). Made it fine.

Got into town, turned left. Grinding.

Now it drives fine but the grinding is more subtle, but happens after just 10 minutes or so of driving. Don't notice it at highway speed, but maybe something feels a little friction-y.

Front brakes are new and close to the rotor but braking doesn't make it worse/better.

Really can't figure this out. Would love your thoughts (so long as those thoughts aren't useless like "you should take it to a mechanic." )

Last time I got a sudden slight grinding noise in a project car I had to drive it around the block for an hour to be sure it did some visible damage that I could find during an inspection. Turned out the new calipers I put on were a little rougher and that was all it took to touch the inside of the wheel barrel during turns.

In your case you mention some new brake parts so I would start there. If you can drive it around the block a few times in low winds, low speed, on pavement only, you may be able to find metal dust. Otherwise you're looking for shiny spots and such where contact has happened.

Grinding noise is usually hub bearing. Loud when turning left means right hub bearing is shot and vice versa if loud when turning right. Changing my right hub cured the loud grinding when turning left.
