W212 E550 Power Steering and Doughnuts
Good afternoon! I was goofing around yesterday in the rain doing donuts in my E550, and after 3-4, I stopped. Suddenly noticed power steering is heavy on low RPM. However, if it sits for a minute, it is normal and gets harder after 2-ish turns. I read a lot of forums, figured it might be the PS pump. Still have hopes that it is not. Any idea how I can check that? No leakings or bubbling in the system when turning lock to lock(at least once). Is there any "re-bleeding" procedure I can try? And is there a good guide on how to replace the PS pump in the worst case? Thanks for the help, everyone!
P.S: Why did I do that? I guess young and stupid do not blend well.

Bleeding involves turning the wheel lock to lock slowly MANY times with the engine running... there are reports of burning up pumps while doing donuts, aka high-RPM and full-lock.
