Some sort of grinding sound...
Good afternoon ladies and gents. So I thought I’d ask if anyone else had experienced anything similar to what I am experiencing with my 1LE. This past Friday and again today I heard a grinding sound while making a right hand turn into a parking garage on Friday, and then a parking lot earlier today. At first my heart dropped because I believed I was curbing my rims while making the turn. There was a bit of resistance as though I was stuck on something as well. I was sure it was the curb. After both instances, I got out and checked my rims and beneath the car for any damage and could find nothing apparent as of yet. Rims and all seem to be just fine. I have no idea what this could be resulting from. I also thought that it was perhaps the splitter scraping the ground but the incline for both the parking garage and parking lot had no significant change in angle. Besides, there was no damage shown there either. If anyone can suggest things I may want to look into, please let me know. I can’t seem to replicate the issue anywhere else while driving. I may have to try to turn into that same lot again another day perhaps but would prefer not to as I don’t want to cause any serious damage if there isn’t any reason to.

something stuck in brakes, like a rock?

Are the grades or angles of the surfaces different from where you were coming and where you were turning into? I've had instances of the rear diff perhaps slipping in instances of turning with different angles of pavement and it sounds and feels bizarre. I wouldn't call it grinding though.

Pulling into my driveway I'll get one rear wheel off the ground, and if I don't let up on the gas or clutch in, it will sometimes make a grind type noise as the eLSD tries to lock up because of the wheel in the air.

Was it a grind or a clicking? If it was more of a clicking you may want to re-torque your lugs to 140 lbft.

I have a weird sound when I back out of the driveway on my way to work and it’s very time I turn to the right or left . Only does it in the morning . Can this be the diff groan I’ve seen on here?

I recently dealt with a low speed scraping sounds when I did 90 degree turns, or close to full lock. It looks like part of the wheel well liner on the passenger side had been sagging and was basically rubbing against the tire when I did high angle turns. I just popped it back up and voila, away it went! The area where my sagged was to the left of the fuse box, so I'm not sure if I was just clumsy and pushed it down when I rested the fuse box lid there, but I'll be sure to be more conscious of it. Not sure if this is your problem since I'm not sure what kind of noise you're hearing.

I was not aware the chassis was so rigid that the angle would cause the car to go up on three wheels. After this incident, I saw the noise was not caused by physical contact and determined it was the diff frantically trying to lock a spinning tire. It happened one more time as I was learning how to navigate the ramp transition. Going up on three wheels while trying to accelerate in a 90° turn at 2-3 mph is not something done in normal situations.

Hard turn? Could it be the edge of the tire was rubbing the inside of the wheel well?

When I first experience this, I also thought I curbed the wheels. Luckily, it was the eLSD, traction control, and/or a bit of wheel spin. My heart dropped thinking it was the wheels were curbed.
