    Dynatrac Dynaloc Hub Rebuild

    Dynatrac Dynaloc Hub Rebuild or Installation

    IMG_0527.JPG

    I am not a professional and have never taken these apart before. I searched and could not find anything online showing how this was done other than a couple bad videos. I reached out to a Dynatrac who was unable to provide directions to me so I was doing this blind. Overall it is fairly easy as long as you take your time. Install time while doing this write up and pictures was about 45 minutes. Should take 15-20 minutes if you know what you are doing.


    Tools needed:

    - Rubber Mallet
    - Flat Head Screwdriver
    - 5mm Allen Wrench
    - 3/16” Allen Wrench
    - Picks
    - Dykes
    - 2 5/8” Spindle Socket
    - Torque Wrench
    - Brake Cleaner
    - Automotive Grease

    You may need a breaker bar and will need tools to remove tires and brake caliper. Not included in the above.

    Bare spindle with new ABS wire installed using a 5mm Allen wrench.

    This photo shows the seal and the first bearing already installed in the hub as I did not need to remove them. Clean the tone rings if required and back of the hub.

    IMG_8649.JPG

    Insert second bearing. You will need to hold the hub up in place until the second bearing is installed. The hub will want to fall until that is inserted.

    Install first spindle nut and tighten to 50 ft lbs using spindle socket and torque wrench.

    IMG_8655.JPG

    Installed spindle nut “lock washer”, second spindle nut and torque to 70 ft lbs. after torque is applied fold over ear of “lock washer.”

    Insert collar and plate. Make sure to push both pieces all the way in. It may be necessary to spin the hub while pushing to get these fully seated. The plate needs to be installed with the dimple facing in.

    Next install spring into locking hub piece. The larger of the two. (If anyone knows the name I will add that)

    IMG_8667.JPG
    IMG_8668.JPG

    Slide brass ring onto shaft of outer hub lock with the bevel facing in toward the axle and away from the teeth. Slide over axle shaft and into hub.

    IMG_8669.JPG

    Install locking snap ring. You need to ensure the entire hub assembly and all pieces are pushed all the way in to fit snap ring into the groove on the shaft. If the pieces are not pushed all the way in you will not get the snap ring to seat.

    IMG_8673.JPG

    Install outer hub locking plate and spacer. Flat side of spacer facing in and flat side of plate facing out. This is what will catch the hub and lock it as it turns.

    IMG_8675.JPG
    IMG_8677.JPG

    Install large snap ring into groove in the hub assembly

    IMG_8680.JPG

    Install dynaloc cover with three Allen bolts

    Nicely done! Is it safe to assume that this procedure could be used with warn hubs as well or are a few of the components specific to Dynatrac?

    Looks good, I’m surprised Dynatrac didn’t have instructions on how to do this

    Thanks. I’ve seen it done from afar in the desert a handful of times and everyone said it wasn’t easy. Was actually a lot easier than I thought. Thanks for the picture also!

    I have no idea. I haven’t seen a warm hub apart before. I would assume it’s similar but something would have to be different since the warm hubs are unlocked when broken or disassembled and the dynalocs are locked when broken or disassembled.

    They have a bunch of links but not a single one works. I emailed them and was told the IT guys email was down and they would get back to me. They got back to me with “there are some videos on YouTube you can look at.” Which he was right there are. But not a single video had this brass ring in them and that was what I had a question on.

    Ha! I would prefer a garage and some poke but I guess a parking lot in Jean, NV and smoked salmon would also work.

    Are the dykes necessary or will regular lesbians work?

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
