Back in the days when I was a line mechanic, I made it a policy to install new locks anytime I had the wheel hubs off. Which Front Differential does your truck have? Anyway, here is what I do with my 94 F250 4x4 with a Dana 50 front end with manual hubs. If I recall there are actually 2 rings that hold in the locking assembly. I used brake cleaner and engine degreaser. You might need to get your fingers or a hooked object in there to wiggle it loose.
Ther are some small screws around the outside of the locker which need to be removed before you can get things out. The locking hub sits inside of the wheel hub. The hardest part is to find and remove the big C clip and to remove the first lock nut. Here is another clip from a previous posting when things were fresh in my mind. Then back off the torque to about 40ftlbs.
Good Luck, Jim Henderson jim? Behind that should be a thick washer with ears that fit in the keyway on the axle, it slides out. This is the one I was talking about. Remove items 1 and 2 also. I already collect electric tools and odd mechanical tools, so my wife would kill me if I got a whole new hobby. I will probably tackle that in spring. With what I now know, I would use the wood block on the end of the spindle routine, hitting on all sides, lots of penetrating oil, and heat. Grease up the inside of the wheel hub where the bearings will sit.
Posted by steve siebenhaar on Apr 4th 2018 I was thrilled to find this spindle lock nut on you web page at a reasonable price. I use a Haynes manual Chiltons is probably also as good for this. The inner bearing sits in the back of the wheel and is covered by the grease seal. Becareful not to damage the rubber seal. Becareful not to damage the rubber seal.
All you need is a small to medium flat screwdriver or something to push the end out. There are also supposed to be some bearing separately on the other part of the hsteering assembly also called spindle bearings, I haven't played with those yet so can't help on that. So in summary, if you have the locking hub out, the big C clip and the 1 inch c clip and both locknuts and flat washer out, everything should just slide out. I highly recommend an impact wrench. The impact wrench took just seconds. Grease up the axle shaft, especially where the surface is shiney.
These little guys are essential for preventing your Spindle Nut from backing off. I have a 94 F250 4X4 etc. I have not messed with that yet although it also is a routine maintenance item. The wheel bearing comes first adn then the wheel. One is the spindle that the rotor, brakes, locking hub, wheel bearings etc rides on. I spin the wheel while I do this to make sure it doesn't bind.
After that you will need the special socket if you want to remove the entire wheel assembly from the spindle. It is held in with 3 different things. And third, I used a chisel to hit on the edge of the spindle and its backing plate for lack of a better word The spindle had no retaining clip on mine, but it fits tightly into the carrier. Be careful and set the locker aside for cleaning and greasing. Those hubs suck it up big time.
You might need to wiggle it a bit but the only thing that should be holdings things on at this point would be crusty grease around the grease seals and the two wheel bearings. The short bent tab fits in the spindle slot and one of the nut slots to lock the nut in place. I forget now but I think they are right hand thread on the right and left on the left hub. Put the bearings back in the hub and then use a new seal, it goes on the back of the wheel hub. I could not do it with any of my sockets or breaker bars. It will slowly force the stud back into it's hole.
The locking assembly will come out easy once this is done. When the manual refers toa spindle, they get confusing since there are two things on the steering assembly they call a spindle. Taking the 6 nuts off, and then knocking the studs out the studs are really bolts that are knurled to fit tightly in the hole, but they easily knock out Once the studs were out, I put a punch through the bolt hole to sort of hit on the edje of the spindle. On my F250 torque is 50 ftlbs. Once the end is loose you just kind of unwrap it from around the insides.
