Grinding sound during off-roading

[Gilligan390]

Hey all,

I took my big bend out for the first time this weekend and when I was on the trail I hit the brakes and heard a significant grinding sound. I immediately pulled over and looked under the bronco did not see anything. After going further I made a hard right turn on the grinding sound came back. It sounded like metal on metal or a rock grinding on something. I limped it back into the road and after about 15 minutes the grinding went away. The grinding was intermittent and only occasional. I was wondering if anybody had encountered this before?

Were you making full lock turns with your trail turn assist on?

Did you have your trail turn assist engaged accidentally? That shit makes some hideous noises.

I did have it on about 15 min prior to that just to see how it worked. Maybe it just didn’t disengage all the way?

They make some seriously awful noise during T.T.A. but if it continued even in a straight line and sounded as you described my guess would be a rock in your brakes. I've had rocks get in between the caliper and the rock guard (ironic) on a number of vehicles and it makes a god awful racket.

THIS Was my EXACT thought as I was reading it.

My grinding is coming from front driverside area. Discovered leaking grease all over and mechanics believe boot is torn but can't locate tear. They're replacing entire left front axel Something to check for your issue, axel seal areas and grease that shouldn't be there indicating a problem.

***(UPDATE)***
Seems the grinding is a different issue. It's still there after replacement of driver side axel. Just happens I had 2 issues at same time same side unrelated.

Check my thread on Grinding issues might be crawler gear related....

Should explain it.

I just had a Drive the Bronco event and used it and it works. Only did it once, it will be nice use it more if I ever get my Bronc. Great for those tight trails.
