Guys, this is my first CTD and I was surprised to learn that the front axle and drive train is turning all the time. Has anyone installed unlocking hubs? My previous 4X4's all had manual locking hubs. I just think it would save wear and improve the fuel economy at the same time when on the highway. Any comments?

Dynatrac makes a kit but they do not list it for an 07 on there web page. Only up to 05. It is not cheap.

I recently installed the EMS kit. It is VERY nice and easy to install. Comes with everything you need

 

Does the EMS setup stick out as far as the dynatrac kit?

 

Curious too...

Also would like to add it would be great if I could just swap to an old school D60 that is knuckled . I might look into this when my balljoints fail me.

 

Thank for the info and web sites.

 

EMS, 2 1/4 inch farther than stock hubcap.
Don't know what Dyna trac is... Anyone?

 

Dynatrac sticks out 2" past the end of the hub cap.

 

my dyna-trac set up sticks out exactly two inches form the center cap. i cut the centers out of the cap and just re-installed them. i installed the dyna-tracs when i replaced the entire front end. i picked up a 1.5 mpg increase with the dyna trac set up!

 

The great aspect of the Dynatrac kit is that the wheel hubs are supported by two greaseable Timken bearings and not a single sealed bearing (roller I think). Think this kit is the bees knees.

At $1475 for the kit and a savings of 1.5 mpg, it would take about 150,000 miles to hit the break-even point.

 

Could wait and use the kit when it's time to rebuild the front. Will ease the burden of cost.

I would also take issue with how much "wear and tear" free hubs actually prevent. It would make sense that spining the front drivetrain must put a lot of wear and tear on it but I haven't seen that. Since the front is rarely under power the amount of stress on it is negligable. The system is designed to spin and one could easily argue that moving the parts keeps out moisture and therefore damaging rust. I've run several 4x4's with and without locking hubs and the Dodge set-up actually is pretty darn trouble free and fairly strong. Besides, it's really nice to have 4wd available without getting out of the truck and locking the darn hubs

 

I think it would be great to have 2wd LOW low especiall when I have to load square bales of hay
