1998 Ford Ranger, AT, 4x4. We want to tow this truck behind our RV. Are there any modifications I need to make? Is there a special transmission cooler I need to install or computer chip upgrade or stuff like that I should do?

Please reply: samwlee7512@comcast.net

Much thanks

 

I have never towed a 4wd myself, but I'll share what I learned from towing my 2wd from Georgia to Arkansas.

It really depends on the method of tow. Are you using a dolly?
Either way, you will need to disconnect the transmission from the axle(s) in one way or another (drop driveshaft). If you let the transmission spin while in "Neutral", even for a short trip, it will build up all kinds of heat and boil your transmission fluid out of the vent. Trust me, I've been there, done that!

If you're using a dolly, put the front wheels on the dolly and drop the rear driveshaft.

 

To prep your Ranger for being towed with a dolly:

1. Using a paint pen, or something simular, mark the pinion flange and the driveshaft so you can bolt them back together the same way.

2. Remove the four bolts holding the driveshaft to the pinion flange.

3. Strap the driveshaft to the underside of the truck. Try to get some forward pressure on the driveshaft so it won't slip out of the trans.

When you reach your destination, undo the straps, replace the bolts, and go.
