hello folks everytime I go up my driveway on an angle I hear a noise coming from the back it seems like the traction control and i notice the rear tire is free wheelin on the air, is this normal? em i going to break something in the future? I have no choice but to go up on an angle otherwise I will scrape my bumper thanks

Are you lowered? Thats normal when your setup has no suspension travel.

When that happens try pulling the ebrake slowly

Yes bro Im lowered on H&R super sport lowering springs.. if I don't pull the ebrake will I break something?
If I pull the ebrake slowly I won't hear that crazy weird noise going up the driveway? thanks

I thought I was scraping my drive at first but for me it was the sound of the traction control kicking in.

Yes it is normal. Welcome to the life of a limited slip differential.

My friend owns a completely stock one, and when they drive up their driveway at an angle the wheel comes completely off the ground also. No mods at all on the suspension. Nothing has broke

If you don't pull the ebrake, you're spinning a wheel in the air. If you pull the ebrake, you're "tricking" the diff into sending power to the wheel on the ground.

I think the noise is not the LSD, esp since our is Torson without clutch plates. Sounds like what is happening is when the one wheel becomes unweighted it spins freely while the car isn't moving so the traction control detects it as wheelspin. It then pulses the brakes on that wheel to stop it.
Pulling the parking brakes should help as it slows down that wheel and gives it some resistance torque. The LSD is a torque multiplier, it will transmit 4x the torque of the wheel with less traction to the one with more, so when you give some resistance with the brake it allows some torque transfer to the wheel still on the ground. If you don't, the wheel in the air has zero torque, and 4x zero is still zero.

What I'm saying (in a different way) is: the noise (whether direct or indirect) is the result of the LSD system working.

Not saying it's clutch packs or brakes or whatever. If you've never sat in a car with a LSD (VLSD is probably the only exception to noise here), that's what it
s like.

It's probably the E-Diff part the traction/stability control program kicking in. The car can use the ABS system to apply the brakes to a wheel with no traction so as to help send power to a wheel with traction.

Normal. Sounds horrible, and has made me stall the car a couple times going up my parents driveway, but it is normal.
