Higher mileage cars can develop creaking and groaning noises in the front suspension, particularly when coming to a quick stop. Inspection and replacement of any worn parts should correct this concern.
If your power steering pump is making noises or leaking, get it fixed ASAP or you will likely be replacing your alternator too. The alternator is located right below the P/S pump and if fluid drips into it it will short out the alternator, this has been occured many times.
Also, if you get a puff of white smoke in the morning it may be a bad speed sensitive steering solenoid, which screws into the power steering pump and has a vacuum line ...

The diagnosis was that the shift solenoid "E" encased in the transmission was faulty (PO770).

After putting the alternator on it ran better than before. But wouldn't keep charge the next day. And that same day when I would push the brake or gas my radio would cut out not shut off though.

We have a 1990 ls400, 160k miles, the power steering pump leaks fluid into the alternator causing it to go out. We're replacing both items but, the instrument panel light is going haywire while this is happening. Does anyone know or have had similar issues & did the replacement of the alternator & power steering pump fix the problem with the instrument panel? Thanks for the feed-back.

I bought this car at a car auction in 2000. It had 86,000 miles on it. I now have over 259,000 miles on it and it runs like a champ. I use a full synthetic oil combined with Lucas Oil Stabilizer, a K&N Oil Filter and I change it approximately 8000 or so. I want to milk this bad boy over 300,000 miles ! The only issues that I have had in the past 11 years or so was the power steering pump and li...
