Because I can afford to take preventive steps and changing the suspension
introduced a little gear whine. Now the car rides like I want it. YMMV.

Does it drive better with the change now? Mine is lowered to and has slight whine, but more so i hear chatter when i go on a bump sideways since the car sways side to side. Hoping that gets relieved with the oil change. I just ordered redline for trans and diff.

Geez. The car is brand new. why are you wasting money?

I have attached a picture of our test car. This is not wasting money. This is the second fluid change at about 9K Miles. The first change was done at about 3K miles.

Hey guys how many quarts are in our diff? And do we have a fill plug on our diff?

Jeff, about 1.6 liters. You want to fill to within just under 3/8" under the fill plug threads.

7000 miles get it changed. Your hurting your car by not doing it.

Wow, I was hoping that by changing the fluid at ~1K I had 'gotten the gunk out'. It looks like it will just keep building up. I wonder if it will slow down at any particular mileage.

Ours get well used Lot going on in a Torsen, other models are mostly clutch wear. It's pretty normal, it's only a concern when the pieces get bigger.

Do you guys hear a slight chatter noise in the rear when going on bumps sideways with lower springs
