anyone know what you do once you get the steering wheel off and get to this point? both the "non-mud" threads i have printed out are a little light on details.
ALSO, is there some kind of mission critical registration marking you are supposed to do? like do i need to do anything before or after this point?
any good links etc?
THANKS
vehicle is a 97 LX 450.

I think you are mixing up earlier and later models. What you have in your picture is a clock spring, but the plunger part you bought is for a '94 and earlier. '95 and above use the clock spring, no plunger.

That substitution is not for LX/Land Cruiser.

The correct substitution part would be 84306-24010.

Might be cheaper to source a good used one.

thanks a LOT for that. i found out about that this morning. not sure what the new part number means. prices are all over the map.

but for 95-97 owners those old wires control your airbag so best to not punt around with it.

i almost feel like there should be an alert i the FAQ about it actually. cruise control or horn not working is one thing. airbag is on another level IMHO.

but i guess if your airbag bulb works it would light up...

hi zapatius. thank again a lot for this. just so i am clear for others.
84306-28020 is superseded with 84306-24010?
and 84306-33020 is not an LX450 part?
is it a 95-97 land cruiser part? it's weird because it prices out almost the same or the exact same but it is shown with two stalks...

This site answers all your questions:

THANKS man. but i'm not following. that's the lexus site. i super don't want to pay $437 for this part. and i don't have a hookup at a lexus dealer so it is unlikely i will get it cheaper than retail.
84306-24010 is the part number for toyota fiche but it also fits the lexus - yes?(!)

As shown by the link I posted, part number: 8430624010 supersedes the other part numbers you posted. Supersession(s): 84306-24010; 8430620040; 8430628020; 8430630060; 8430633020; 8430650080; 843102L080. And it fits your LX 450. I'm not saying that you need to buy it from Lexus, but pretty sure that is the part you need.

Okay, let’s take a moment and try not to over complicate this. Or ask questions within questions so many times it become a question inception nightmare.

You already answered your own question. The partsouq part numbers your posted both work. Find a dealer that has one of them and buy it.

thanks for all that. i APPRECIATE that.
i called NAPA this morning and they wanted $625 so i kind of went down the rabbit hole today.
some come with two stalks. some don't. some are unavailable. then there is the lexus thing to figure out.
i mean i guess the toyota version contains enough wires to control the old telephone controls on the lexus or something. or at least it would be good for others to know that there is nothing lexus specific in the steering wheel or controls?
also i was sort of laughing to myself that i went in thinking i had a $10 part and i am into the repair now for almost four bills.
/anyway/ that is a long way of saying i could see this intel being in an FAQ. the trucks are 25 years old and the cable in this part contains the sensor to trigger the airbag.
meaning i might have gone in and replaced this right after finding out i didn't have a heater core leak and then doing suspension i suppose. 😊

That one number you posted is for the ES series of Lexus cars. The one I posted and everyone after me is for your LX. You can get it from any Toyota dealer, Ebay, Megazip, Partsouq, flea market, etc....

How do you know this part is bad on yours? Did you test continuity at the horns?

33020 is the part that doesn't fit on yours

As a cheaper alternative, you could just get a sticker that says "Horn broken, watch for middle finger"

ah crap. thanks man.
i need to study what you posted. sorry.
on diagnostic i tried for awhile to figure out what i needed to do. basically all i did was clean the contacts and ground at the horn. also to inspect and replace the horn fuse.
i wanted to test continuity at the horn and also i thought to test the actual wire now that my wheel was off.
i have a used fluke i bought for $50. i just wasn't totally sure where the probes went to test continuity or which settings i should have it on...
