I am in need of a master list of the OEM makers of the parts on my '96 Lexus LS400

most of these parts seem to be single sourced or dual sourced in a few cases
and often the OEM is NipponDenso

like, for example

Idle Air Control Valve - NipponDenso
Air Conditioning Compressor - NipponDenso
Spark Plugs - NipponDenso
Oxygen Sensors - NipponDenso

but what about a more complete list, for example, who makes the tie rod ends? - or the upper control arms (those wishbone looking ones)? or the alternator or starter or PS pump or window motors or fuel pump? etc.

 

hard o determine unless you pull a car apart, but just pick any aftermarket part that's made in japan, as pretty much none of the major components are made anywhere else afaik.

 

again, just querying the collective knowledge of Club Lexus - if you have replaced a part on your LS400 with the real Lexus part and you know who actually built the part originally (should be same company that built the replacement) then please post that info!

example: after determining the precise manufacturer and original part number of my upstream oxygen sensors (NipponDenso) that cost $327 per pair at the dealership, I was able to locate the same exact NipponDenso matched pair brand new in the box online for $98!!! - that's HUGE if you ain't rich!

Information is power and there is a goldmine here if we can get CL users to regurgitate their collective wisdom!
