Should Sport Mode Shift to 4x4?

[Jesse-Infotainment]

I’d like to add 4A to my ‘21 Tremor. How did you add it? What did it cost?

It was a transfer case and a module and the selection knob. The case was the most expensive. I think $1000 or so.

No wiring or anything. Was some progrmaming via as build data changes.

I do not knwo if there would be anythign different about a tremmor..

My 2021 Platinum Powerboost had 4A transfer case AND E-IWE hubs

My 2022 KingRanch Powerboost has 4A transfer case and no IWE at all.

I don't think the 4A transfer case requires either IWE option. And I don't think the front differential is different between the XLT or my 2021 Platinum or my 2022 KingRanch

I have NOT compared part numbers to prove my assertions either way.

Note that Ford recently released a TSB for earlier generation F150's that effectively is an IWE delete. It literally removes vacuum permanently from the IWE's and caps off the vacuum lines. I can't believe it took them so long.

I also have a 22 KR PB, how does it not have an IWE?

because now on the 4A transfer cases the front end never dis - engages it freewheels
all the stuff rotates .
