Default Re: Wheels-Caps

Yes the early 4x4's, back to 1941 Jeep, had an in/out lever and a Hi Lo lever. Even when in OUT-HI, the front drivetrain was turning. I see now this is the type we are talking about with the 62. Albeit just one lever. My bad.
As BBV6 says, They came out with what they called "full time". Even though it did not have to be in 4x4 all the time, you could drive it in 4x4 all the time if you wanted to. Still had "in/out". However it had a differential inside the transfer case so that you could turn corners and drive on hard surface in "FULL" 4x4 mode, which you should not do with the part time T-cases. That system used the 203 xfer case. You can't just add hubs to that unit to switch to part time. You can add hubs, as mentioned, to the T221 and others to free up the rotating front drive train. T221, NP205 and others are Part Time only cases. Meaning you can't run around the streets in 4WD unless you live on dirt roads or in the swamps.
I was lumping all systems without locking hubs as Full Time.

The part in red is wrong. I was wrong again. You can only technically operate in 2WD with a 203 if a conversion has been made. The only thing worse than being wrong is not admitting it. Thanks to BBV6 for trying to set me straight. I had a mind block. Back in the 70's I was taught that any Chevy 4X4 without hubs was called full time and with hubs was called part time.
