How do i install power steering hose on a 1991 lexus 400

You can get a dye to put in the power steering reservoir it makes the fluid glow

There are two lines. One is a high pressure and one is a return line. They both run from the pump to the steering box.

The main purpose on an alternator is to recharge current back to the battery. One of the most common problems with the Lexus LS400 and SC400 is that power steering pump seal leak. Right below the power steering pump is the alternator. The power steering fluid will drip down and cause many electrical problems for the alternator. Therefore, its very common to have the alternator go bad along with the power steering pump, just be sure to check.

if its not leaking from hoses try replacing the power stering pump seals

the pressure hose runs along the oil pan .

may need a code put in for the computer to work

As mentioned check ps fluid. If it wines when turning and still no power then the pump is internally bad.. If the fluid is dissapearing fast then its a hose or most likely a leaking rack& pinion assembly..

Glad to help.

The leak could be in the steering rack.

There is a loud squeak on the front of my 1991 ls 400. The squeak is near the alternator. Any one no what it is?
