My FJ62 feels likes it’s 1 wheel drive out at Cape Lookout (1 Viewer)

[TheElegantFox]

Think I found a replacement front drive solenoid: https://shop.cruiserparts.net/index.php?main_page=product_info&products_id=65334

Pretty steep but it's NLA from Toyota direct. The hub repair is out of my wheelhouse though, I can’t safely jack up the vehicle or put it on jackstands. I'm limited to a gravel drive in the city.

I'd be looking at converting to manual shift if it were me and I planned on keeping the truck for a long time. Won't be cheap, but that would be my preference.

Would that be swapping in an FJ60 transfer case? I’d have to pay for a shop to do that.

No, you can convert your current case to manual shift.

Convert FJ62 Transfer Case to Manual Shifting, and some other questions...

Hey All. Is there a kit out there so I can make my t-case shift like the one in my jeep. Fully Manual, with no electronics. I do not know exactly what model t-case i have, ( would appreciate someone telling me, or pointing me in direction of a page that lists its name ) Another question is...

Looks like SOR sells single VSVs and I only have one bad one, could this be worth a shot? Land Cruiser Vacuum Transfer Shift Assembly 8/87-1/90 FJ62 - https://www.sor.com/cat072b.sor

Here's a much cheaper alternative if you're just looking to replace the solenoid.

I have also mentioned to you that I have both of these parts on the shelf....

Will they fit the OEM bracket?

Yes, they are factory OEM FJ62 from my twin stick truck.

While I agree, you are not getting vacuum from the lower VSV. Something else is still not allowing your transfer case to slip into four-wheel drive and we have to figure that out first.

The big vacuum diaphragm on the side of the transfer case where those two larger vacuum hoses go is the next suspect.

ONSC tech day anyone?

I should bring the truck out to the next meet, I need to actually meet the club I joined, in person haha.

Replaced the solenoid with another Toyota one from another thread. I’ll get the part number when I’m back at a desktop. No change in behavior and no lucky green 4x4 light. I’m thinking either that wire into the red VSV is dead or the switch at the dash ain’t doing jack.

Does that new VSV pull vacuum now when the switch is pushed?

I thought we had already determined you had a different issue....

Something is preventing the vacuum diaphragm on the transfer case from actuating four-wheel drive.

It doesn’t send a vacuum feed out but it’s getting the same feed in, so I think the switch isn’t happening electronically.

If you switch the vacuum lines the switch doesnt do anything. Even the light is controlled by the vacuum actuator in the transfer case.

So if the red vacuum switch never sends a signal and switching the lines also doesn't engage the switch, what's the next point of failure to investigate?

The diaphragm on the tcase, if i'm following this thread correctly.

Ah ok, looking at this thread: FJ62 vacuum diaphragm kit? - https://forum.ih8mud.com/threads/fj62-vacuum-diaphragm-kit.975703/, it seems like a good next plan is to clear the gunk out of the piston.

 

[TheElegantFox]

What tool would I use to test if the lower VSV is getting power?

 

[GLTHFJ60]

A multimeter.

Again, it doesn't matter, because when you switch the at the correct VSV, constant vacuum is sent to the diaphragm on the case, which should cause it to engage 4wd.
