4x4 engagement

[BrentBronco1987]

So now that my 87 bronco 4x4, with the 305 and c6 transmission, is running I want to see how she does in 4 wheel drive.. how do I do this properly. I've seen people put it in neutral and do it but she grinds when I try.. I am able to shift it only when she is off and in park.. the neutral safety switch must be bad bc I can start her in park.. could this be my problem?

305 engine? Should be 302 unless its modified in some way I'm not aware of.

The 87 Bco has a shift on the fly t-case. As long as all your wheels are going at the same speed you can engage 4x4 high at any time.

• Lock the Hubs
• Switch to 4 high.
• enjoy

In the winter time I leave my hubs locked and drive around in 2wd HI till I hit something that need more driving force.

For 4x4 Low you must

• come to a complete stop,
• shift to neutral,
• Move the t-case to the 4x4Low position.
• Then you can place the transmission back into gear.

To take it out of 4L

• Come to a complete stop
• Shift to natural
• Move the t-case selector to 4hi or 2wd
• shift the transmission back into gear

Simple once you know what the steps are.

You noted that yours grinds when your trying to shift, I would inspect the shift linkage to make sure it is all in the proper position.

It is a 302.. that was a type o

Next step is to get rid of those hat style hubs only found on the 87-88 models by replacing knuckles out with 89+ parts. A good time to do this is when you need ball joints anyway.

Come to a complete stop, neutral or park. Then engage. To deactivate, stop and disengage, then go in reverse for about 12ft. Then put it in drive.
