@Dave mine was an 01 EB too.

Dave

I think the auto engagement of the awd is stupid and i cut one wire on top of transfer case and it will never engage awd again i can still shift to 4×4 from selector

1
Dave

@Matt. Probally ordered with that option maybe

0
MattQuestion author

@Dave I see its purpose, but I still prefer to have the option to lock it in 2wd only.

0
Dave

Thats why i cut the wire on mine makes it stay in 2wd then if u need 4×4 u just change selector to 4hi or 4lo

MattQuestion author

I’m glad my 05 has the 2wd only option on the switch…gives me more control of what the truck is doing.

1
Dave

For sure not being able to be in 2wd in nice weather is ridiculous

1
Chad

Mine I a 99. Wish it had to 2wd option. Don’t care much for a4wd

0
Dave

I know how u fix that problem

0
Dave

Dosnt cost a penny

0
Dave

@Chad this only is for models that on dash say a4wd.4hi.4lo
Its very simple this is what i did there is a single gray wire in a black wire loom all by its self that goes to top of transfer case u cut that wire .what that wire does is when rear tires slip transfer case engages front wheels .it wont do that anymore it will stay in 2wd and when u need 4×4 u simply just change ur selector on dash to 4hi or 4lo .its as simple as that .no bs thats how i did my 01 eb way better so u dont have a slip of the rear tires and while its spinning the front shaft thats not gets slammed into engage .stupid system.do it and u will thank me .takes 5 mins and a pair of wire dykes

If I make Sharp slow turns like pulling into a parking space. Not cranking the wheel all the way, I get a little jumpyness or weird noise from front end. Got an idea what that could be?

0
Dave

The awd cut that wire u wont have those issues mine is same setup as urs and it runs in 2wd now enless i need 4×4 like i did today with this blizzard

0
Dave

Its a bs system cutting this wire makes it operate like a normal 4×4

0
Chad

@Dave my dad has an 05 f150 with the 2wd 4hi and 4low setting. His doesn’t do that when turning so I suspected it was the a4wd bc his doesn’t have it

0
Dave

U could have a alignment issue to i dont know how the maintenance is on urs

0
Dave

Mine dosnt do it either

0
Chad

@Dave I Haven’t Had IT long. Maybe a year. It’s really clean inside and out so I assume it was taken care of. Might be an alignment issue, my steering wheel isn’t perfectly straight when driving down the highway

0
Chad

It’s close but not exactly where it’s supposed to be when driving straight lol

0
Dave

But i have a brand new front end parats tires and alignment on mine to

0
Chad

I need shocks and probably need upper and lower ball joints. Everything looks original down there lol

0
Dave

U might have a tie rod bad or out of alignment that will cause it to bit that awd bs is for the birds

Thats a huge topic with these modular motors alot of people get very inconsistent hp numbers
