Spyntec or Dynatrac

[StHubert]

I have an 2001 Excursion 7.3l. I need to replace the hubs in the front and have been contemplating using the Spyntec or Dynatrac conversion kits to replace the whole hub assembly and have manual lockouts. Has anyone used these and how do you like them. Also, what do you do with the vacuum line since you be using them to lock out the hubs? These aren't cheap so I just want some opinions before I pull the trigger.
Thank you very much for any responses.

Could someone explain to me why one would spend all that money when you already have manual hubs with the auto hubs????

ipz2222, Auto hubs suck. they never last with over sized tires and TQ unless you keep it on the pavement or really lay off the skinny pedal. First time you get a tire in a bind, the hub it gone. And if its a stock axle, its going to be the short side. (less deflection in the shaft being shorter than the other makes it go before the long side) Every truck i have ever had with them, the first thing i do it get the manual kit and toss it in the back, and everytime, it has been used.

StHubert, I picked up a set of 60's from Dynatrac a while back for a crawler. Although i never delt with Spyntec, Dynatrac has awsome customer service. Since no one voted for you, ill speak mine i guess.

HostileWes, thank you for the reply. I went with Dynatrac, they just came by UPS yesterday. I guess I got a weekend project.

StHubert, Good deal. I missed the part about the the vacuum lines. You have two choices. There is a electronic box that when your transfer case sees 4X4, creates a few inches of vacume, locking the hubs. Some manual hub kits tell you to unplug this box, this can cause a light to come on with the computer thinking there is a issue in the system. Just do the old school fix, plug the end, zip tie it to the axle tube and the computer will never know the diffrence.
