Vacuum shift motor inexpensive fix
I've done this install a couple of times now. First on my old YJ and second on my Dodge Ram last weekend. It is a simple process and it costs very little.
Here's how you do it.
1) Remove the 4 bolts that secure the shift motor to the axle housing and remove the shift housing assembly(careful some 90wt will pour out so have a drip pan handy).
2) Remove the 2 "E" type retaining clips that hold the shift fork on vacuum motor and the 1 "E" type retaining clip that holds the vacuum motor to the shift housing.
3) Pull the vacuum motor out of the shift housing which will slide the shift fork off the shaft.
4) Take the shift motor to the hardware store.
5) Buy a long spring that is just large enough to slide over the shaft of the vacuum motor shaft and take it home.
6) Slide the spring onto the shaft of the vacuum motor, put the shift fork back inside the shift housing and slide the vacuum motor back inside the housing so as to fully compress the spring. The spring will be too long so make a rough guess as to how much to trim off so that the vacuum motor will go all the way back into the shift housing.
7) Once the spring is the correct length slide the vacuum motor back in and install just the 1 large "E" type retaining clip that holds the vacuum motor into the shift housing. The other 2 are no longer needed. (Yay, left overs)
Slide the shift collar inside the axle housing over to engage the front axle.
9) Reinstall the shift housing back on the axle housing making sure to align the shift fork up with the center of the shift collar inside the axle housing. Also be sure to add a bit of RTV gasket maker to prevent leaks.
10) Top up the fluid level in the front diff, and go for a test drive to make sure it works.
