I would change the brake fluid and power steering fluid too.

NO limited slip additive on the rear end. G80 does NOT need it. Just straight fluid.

I'd flush the brake fluid and powersteering fluid as well. And the transfer case and both diffs.

I changed my diff fluid out with amsoil and used there little pump, 100X easier than squirting a bottle into the hole.

That's good info about the amsoil pump. How would you flush the brake lines?

Suck the reservoir dry with a turkey baster fill it with new fluid and crack all the bleeders lose one on each caliper. You need a catch can for the fluid. Give it 10 mins or so make sure the reservoir doesn't empty. It shouldn't take more then 1.5 qt of brake fluid and get 4 new bleeder screws before hand. You will probably end up rounding some/all of them off.

rear diff drain plug

There is a drain plug on the rear diff, it is located directly under the diff/on the bottom you will see a square hole, i think its a 1/2" drive, maybe 3/8, either way a ratcheting wrench in the proper drive size will remove that plug. FYI, i have seen the diff so covered in dirt you would not know this plug was there.

Good call on the new bleeder screws. :thumb:
