DIY Spyntec Lockout Hub conversion
Have a copy of the spyntec install instructions handy, read it to the end. Use this instruction at your own risk, I am
not an expert and there may be alternate methods to use. this writeup is based on my experience with this kit.
Experts be kind... havent tackled hub work in a long long long... no longer time...
4 ton floor jack
6 ton jack stands (or equivelant)
lug nut socket(s) various sizes.
4mm, 5mm allen sockets
13mm, 18mm 1 11/16" sockets
3/8 drvie inch lb torque wrench
1/2 drive ft lb torque wrench
1/2 drive 4 lug internal 76mmx80mm locknut socket p/n25966 at autozone.
Royal Purple grease
1) put axle on jackstands & remove both front wheels. make sure the axle is level, prevents fluid loss.
2) remove brake/abs line bracket from axle (13mm socket)
3) unclip abs wires from brake line so the caliper can be move out of the way
4) remove brake caliper (18mm socket) and place on the ground out of the way.
5) remove rotor
6) remove the abs sensor using the 5mm allen socket and move out of the way
7) using 1 11/16" socket & impact gun, remove cotter pin & axle nut
9) loosen the 4 hub bolts and back out approx 1/4" or so. (18mm socket)
9) using 18mm and stubby extension, place socket up against the back of one of the hub bolts and turn
the steering wheel so that it pushes the socket up against the hub bolt... you may need to start the motor
and use the power steering to assist pushing the hub out. Gently push on the bolts with the steering,
move the socket to another bolt on the other side of the hub and repeat until hub breaks loose.
10) once the hub is loose, remove the bolts and slide the hub off the steering knuckle & axle
11) using screwdriver, pry out the axle enough so it starts to move out of the axle housing, once it is on its way out,
you will want to support it on its way out. There is a seal on the inside of the axle you do not want to damage, so be
aware. I pulled the axles out 3x so far and have not needed to change the seals... no leaks.
12) using 2 screwdrivers, pop out both retainer clips that hold the u-joint in place
13) using a large socket as a reciever place under one side of the u-joint and using a 2nd socket on top, tap the top
socket to push the u-joint out on one side so that you can remove the cap, flip the axle over and tap the joint back into
the 1st side so that the joint will move enough to come out, then tap out the other cap. (there may be an easier way)
14) re-assemble using the new shaft and MAKE SURE YOU PUT THE SHIMS ON THE JOINT BEFORE YOU RE-ASSEMBLE... this was not
in the instructions so I had to pull it appart and do a do-over. the screwdriver is there to allow you to see the shim.
The shim goes between the clip & the yolk. replace the clips.
15) using a cut off wheel, shorten the hub bolts by about 3/8 of an inch. I found it easiest to cut the 1st bolt down
after measuring it, then using the hub as a guide... made it pretty easy.
16) clean the steering knuckle surface using a wire brush
17) reinstall axle, put a light coating of grease on the end prior to installing & be careful of the seal when installing
it. you may need to rotate it slightly to align the splines.
18) put anti-seize on the knuckle face & bore (per the instructions)
19) slide the seal that goes over the mud slinger so that the lip is towards the outside of the truck. this is the
surface that will seal against the spindle. put a light coating of grease on this lip.
20) install the thrust washer over the stub shaft, instructions were not clear on which way it went so I put it with the
flat surface facing outward. there is a beveled edge on one side, (experts please chime in here...)
21) install the small v-lip seal in the back of the new spindle where the roller bearing is.
22) install the dust shield between the knuckle & new spindle and using the cut hub bolts, bolt the spindle to the
steering knuckle. Anti-seize is your best friend...
23) reinstall the ABS sensor using the 5mm allen socket, careful as they break easy over time. I had to use some force
to wiggle it back into the sensor hole. You may need to bend the shield back into place. make sure there is enough
clearance for the rotor.
24) install the v-lip seal over the hub & put a light coaging of grease on the v-lip.
25) pack the *&$^ out of the outer wheel bearing using your favorite method or tool. I tried a bearing packer tool but
just made a mess and resorted to the old method of packing it using grease on the fingers and working it into the
bearing. sorry, no pics... too messy.
26) install the bearing into the back of the hub
27) using a hammer, tap in the rear seal into the hub
28) now pack the cr@p out of the rear bearing, seal with grease... clean the inside bearing surface with a clean rag,
this surface will sit on the spindle and should not spin so grease here would not be good.
29) slide the hub onto the spindle.
30) now pack the cr@p out of the front bearing and slide over the axle into the hub. Push it all the way up as far as
you can, the hub should be centered on the axle.
