Owner report 10253002 · 2008-12-29 (December 29, 2008)
ITS WELL KNOWN THAT THE POWER STEERING/ALTERNATOR SETUP ON THE 1990-1994 LEXUS LS400S ARE POORLY DESIGNED. THE POWER STEERING PUMPS ARE KNOWN TO SPRING LEAKS. THEY ARE LOCATED DIRECTLY OVER THE ALTERNATOR CHARGING SYSTEM AND THE LEAKING FLUID SHORTS OUT THE ALTERNATOR, LEADING TO FAILURE. I HAVE HAD TWO OF THESE AND BOTH WERE LEAKING AND AFTER RESEARCHING, ITS HARD TO FIND A 1990-94 LS400 ON THE ROAD THAT DOES NOT HAVE A LEAKING POWER STEERING PUMP. THE PUMP SEALS SHOULD HAVE BEEN BETTER MANUFACTURED, PLACED IN A DIFFERENT CONFIGURATION, OR…
