Sure would be great to start a thread for rounding up all known LS400 OEM's by part type, would save us a fortune on buying many parts directly as OEM brand vs. buying the dealership blessed version of the exact same part for 4 times the price!


I'll start:

struts - KYB
shocks - KYB
oxygen sensors - NipponDenso
water pump - Aisin
radiator hoses, rubber fuel hose, most other hoses - Toyoda Gosei
air filter - Toyota Boshoku, NipponDenso
oil filter - Toyota Boshoku, NipponDenso
cabin air filter - Toyota Boshoku
TPS - NipponDenso, Aisin
ECU - NipponDenso
Crankshaft position sensor - NipponDenso
Camshaft position sensor - NipponDenso
Engine Coolant Temperature Sensor - Ohizumi (NTC), Semitec
thermostat - Kuzeh
timing belt - Bando, Mitsuboshi
serpentine belt - Bando, Mitsuboshi
ABS modulator - NipponDenso
windshield - Asahi Glass
Idle Air Control Valve (IACV) - NipponDenso
Idle Air Control Valve bearings - NSK
stereo - Pioneer, Nakamichi
spark plugs - NipponDenso, NGK
spark plug wires - NipponDenso, Sumitomo
most interior parts such as seats, trim, headliner - Toyota Boshoku
weatherstrip, door/window/trunk seals - Toyoda Gosei
alternator - NipponDenso
idler bearing - Koyo, NSK
timing belt tensioner bearing - Koyo, NSK
timing belt hydraulic tensioner - NTN
fan clutch - Aisin
A/C compressor - NipponDenso
A/C pressure switch - NipponDenso
engine oil - Mobil (but to a unique Toyota specification that exceeds Mobil's other synthetics)
oil pump - Aisin
transmission - Aisin
transmission fluid - Mobil (3309)
wheel bearings - Koyo
distributor caps & rotors - NipponDenso
brake calipers - Akebono, Aisin, Sumitomo
brake pads - Akebono, ATE, Sumitomo
brake rotors - Kiriu, ATE
starter - NipponDenso
headlights - Koito
brake lights - Koito
turn signal lens assemblies - Koito
strut bars (caster arm) - Toyotetsu (Toyoda Iron Works)
tie rod ends - Toyotetsu (Toyoda Iron Works)
upper control arms - Toyotetsu (Toyoda Iron Works)
door lock actuator motor - Mabuchi
airbag sensor - Nippon Denso

 

I would love to know the OEM for inner & outer tie rod ends, strut rods, upper control arms, bushings, and other suspension components, if anyone can contribute on that.

 

Awesome thread is awesome, however, isn't the trans fluid strictly Toyota T-IV whereas the power steering fluid would be Mobil? Just wondering.

We need an aftermarket section thread, I might sort all these into categories in my spare time. This is great info.

 

Toyota doesn't manufacture any fluids, they buy them from the petroleum refiners, Toyota T-IV is just relabeled Mobil 3309 ATF that is just sold in a Toyota bottle. It's Aisin who specifies this fluid.

and if your Mazda dealer has a better price, you can certainly buy your Mobil 3309 from them:

 

advics also makes oem toyota pads..

 

that's true, but they never made the pads for the LS400, they weren't even around back then

 

I've been underneath my car for the last half hour or so, and the back of my calipers are marked "Sumitomo." I see you stated Akebono as the OEM supplier and Sumitomo as a possible pad supplier, but would it be possible for Sumitomo to have made the calipers as well? Mine's a '97.

 

not only possible, but probable, I inadvertently left them out - oops!

however, many LS400 calipers 97 and earlier were Aisin

 

the problem i see here is that toyota has used different manufacturers for the same part in the SAME YEAR, and uses different manufacturers for the same part across different years. so this would only be useful if you say what years that manufacturer made said part.

'95-00 afik:
Air filter:NipponDenso
Front brake calipers: Sumitomo

more when i have time and rest

 

speaking of Sumitomo, I understand that they are no longer in the caliper business, and that Advics has bought up all of their plants and tooling etc.

 

could we get some more input on this?

you guys (and gals) must know a few more LS400 OEM's to add to the list!

 

good info! never knew this, though type-iV is pretty cheap to begin with.

i would assume toyota actually makes the tie rods, and suspension components besides the struts themselves.

 

if you price it out, you'll find that the toyota price for T-iv is actually the lowest you're going to find that fluid for usually.

 

I know the headlights, turn signals, and pretty much all the "lens" on Toyota vehicles are made by Koito.

 

どうもありがとう muchas gracias!!
