my 4x4 seems to not work and its not my front axel, so people have told me that ther was a vacume hose to my t-case that could be broken. but i cant find it nor any pictures. can anybody help?

ON that back of your t-case will be a square looking plug with 4 different color hoses running of off it. It will cross over your t-case and go to a connector onyou riht side frame rail, the connect to your axle via 2 rubber lines.

Most of the time the problem is either in the hosing, or the actuator is bad. If your t-case was messed up you would know.

hey is there any way to get rid of the vacume lines and put something elce that manualy locks the front end- cuz the vacume lines suck and im tired of mystery wires

You have several options depending on how much you want to spend and your level of mechanical knowledge. The cheapest would be to lock the shift collar in place with either washers on the shift fork shaft, or a nut and bolt. On the other end of the scale would be to install a Posilok cable system that will allow you to manually engage the shift collar when needed. If you have the tools, the know how, and the time, you can swap the two piece passenger side axle shaft with a one piece from a later model. If you go with the axle shaft swap, then get both sides from a 95 and up. It will have the larger, stronger u-joints for added strength.

how much does a posilock cable system cost

winston427

Just a little over $200.

ok thanx

now if i just locked the collar in place -wouldent that mean that my 4x4 will always be engeged?

No, your 4wd is only engaged when you engage the transfer case. All the shift collar does is lock the two piece axle together to supply power to the wheel. The problem with it is that an open differential (meaning without a locker) is that it supplies power to the wheel with the least traction. Therefore when you engage the tcase it tries to turn the passenger side tire which will only turn the inner part of the axle shaft if the collar does not engage.

so my locker wont work?

winston427

Do you already have a locker installed?

CHIF8008

i believe so, but idk the guy i got it from said it had a dotroit locker how can i tell if i got one?, same as for the rear

winston427

For the rear, raise both tires off the ground and rotate one tire by hand. If the tire on the other side spins in the same direction then you have a locker, if it spins in the opposite direction then it is an open differential. The same process would apply for the front, but if the shift collar is not engaged then the other tire will not spin at all. Try this, raise the front end and support it on jacks stands (safety first). Remove the shift motor from the passenger side axle housing. manually slide the shift collar in place to lock the shaft, then try the process of spinning a tire.
