From the VW Vanagon Syncro forums I've read that lock-up in a viscous coupling depends on the temperature. At around 90C a stock coupler will start locking up.
VW Vanagons have their viscous coupler in the front differential case, which warms up as you drive. Justys (and my Subaru Domingo microvan) have the viscous coupler in the transaxle, which is heated/cooled by the engine.
My 4WD has become very 'grabby' since replacing my 85C thermostat with an 88C. Wondering if I should try to fix it by switching again to an 82C thermostat to keep the transaxle cooler and stop premature viscous coupler engagement.
The real fix is to service the viscous coupler but that sounds insanely expensive...

I'm almost certain that mine has one. FA8 Subaru Domingo, Japanese Domestic Market. 5-speed manual transmission with no 4WD pushbutton.
By 'grabby' I mean that, when warm, the van can't do anything more than a 90 degree turn without the tires scrubbing.
I've checked tire pressure, and even measured height with a ruler (they're within 1mm of each other). I'm really suspecting that it's because the viscous coupling is slightly burned and is engaging at the 88C engine operating temperature. Supposedly it should engage at just over 100C, but mine is getting old... Getting it out of the garage is easy - parking it again leaves rubber in the laneway.
deegore: I slept in my 2 door driving from AZ to MN. Some front seats that fold flat would be necessary to really get comfortable.

justytrudeau: FWD means you don’t have to worry about any problems that can come up with the AWD system. AWD is clutch in snowier climates, but the pre 90’s models have carbeuraters instead of being fuel injected. Carbs can cause some issues in the winter time.

justytrudeau: Anyone put LED's in their instrumental panel? I have to remove the whole dash to get to 'em, figured it'd put off having to do it again by a few years.

Justy1200cc: bredmirror, if you do it you would need the suzuki transmission. I think it's searchable on the forum for more details

bredmirror: Thats what Im planning to do. However, if the engine and the transmission won't fit then Im just gonna upgrade the stock engine and get a tubo kit for it.

Justy1200cc: I bought a pink sti badge off wish. it was pretty big and when I found a real sti the logo was even smaller than the justys
