I posted on here a few months ago trying to determine the source of a grinding noise coming from the front driver's side of my 1999 toyota 4runner 4wd. The noise only occurs when there is a lateral force on the front wheel during a right hand turn. After receiving responses on here and elsewhere, I determined that the problem must be the front wheel bearing. As a result, I replaced the bearing and to my dismay it did not remedy the situation. The only other thing I can come up with is that it must be a bearing in the front differential which sounds like a serious pain to repair. Does anyone have any idea what the problem could be? Thanks in advance.

It appears that there is not any rubbing going on. I know what you are talking about though because when I reassembled the spindle assembly after the bearing replacement I slightly bent the shield and it was rubbing on the disc. But that was a completely different noise. More of a screech. The problem noise is more of a low pitched grinding noise which seems like it can be somewhat felt through the floor as well as heard.

The bearing is a sealed unit. I had to have a machine shop press it out and the new one in. The splash guard in the wheel well fell off a long time ago and there are no other signs of any kind of rubbing. The brake caliper somehow actuating is interesting though. I will check into that but I am fairly certain that is not the problem. The amount of turning it takes to make the noise is speed dependent. At faster highway speeds it only has to be a minor curve in the road while going slower requires a sharper turn to make the noise. The bearing is a sealed unit.
