1985 toyota 4runner
going down hill, extreme grinding sound
she would stop accelerating and then it would whine loudly
but when she came out of gear all the bad sounds would stop
but then she would lose power to Steering AND brakes
but like intermittently or like flickering in and out
but she was still able to downshift and did not stall
still running, still has electric, but couldn't keep driving without the brakes.
I'm confused because AFAIK the power and brakes should be completely independent systems although I did read that maybe the ABS uses power from the steering on some models?
all tips welcome hoping to avoid a long delay and mechanic visit.
Thanks!

Given the symptoms, it could be a problem with the powertrain or drivetrain. Probably, there's an issue with the transmission, differential, or even the transfer case. Also, maybe, check the transmission fluid level and condition.
Regarding the power loss to both steering and brakes, while these systems are typically independent, there could be a common issue affecting both. This be a problem with the power steering pump or a vacuum leak messing with the brake booster.
As for the rattling sound coming from inside the motor, this could mean an internal engine issue, like maybe, a worn-out bearing, piston slap, or even a damaged valve train component.
