    Recently I had my front CV Axles replaced and when they installed the axles they left one hub locked in and one hub was free. I've driven it now about 200 miles and I'm wondering if I've done any damage. Or if I'm going to be looking at future damage. I feel crappy right now because I didn't catch it. I felt the vibration and it seemed weird and I got out and I checked the hubs and they're both free but one hub won't engage into locked position so I'm assuming that it's locked in. Geez it may be more than 200 miles. Anyway I'm gonna bring it back to the shop that did the work but I want to know if I need to have them check anything else for damage. Edit it's a 2000 Tacoma

    Absolutely no damage.

    Your cv axle simply spun with your wheel, the same way an ADD setup traditionally does.

    With that said, it sounds like one of your hubs was assembled incorrectly. Just remove it and reassemble correctly; it's crazy easy.

    Ignore the red color, they're Tacoma hubs that I simply painted to match the old Pick Ups

    Keep in mind that this instruction below is *not necessary* as your hub was pulled out as an assembly and not taken apart as shown.

    Doing this for educational purposes but if you do disassemble for a rebuild, you'll want a new o ring, gaskets, maybe even a new spring or two along with the ball bearing in case you lose one or two

    Start with your new o ring on the dial; sil glyde on the ring is your friend here

    20200727_180747.jpg

    Little detent spring; I had one that was broken but you can buy these little kits with replacement parts I think from Yotashop or some other vendor online

    I used redline grease on it cause metal on metal

    20200727_180805.jpg

    The little ball bearing

    20200727_180841.jpg

    This is what you 'feel' when it engages/disengages on the hub dial

    20200727_181026.jpg

    Dial going into the ring; take note of this little notch here for the detent spring and ball to go into

    20200727_181125.jpg

    Self-explanatory

    20200727_181133.jpg

    20200727_181237.jpg

    20200727_181351.jpg

    From left to right, the clutch, the spring, and the pawl

    You have two springs; this one will use the smaller set with the end bent upward

    20200727_181551.jpg

    That spring goes inside the clutch, this is your guide here; grease where applicable

    20200727_182234.jpg

    Spring installed

    20200727_182335.jpg

    And that bent portion on the spring is where the pawl catches

    20200727_182418.jpg

    More angles

    20200727_182550.jpg

    20200727_182602.jpg

    You'll take your partially assembled hub dial, along with this spring, and set it aside as you'll use it later like this

    20200727_182816.jpg

    20200727_182914.jpg

    All that's left is the hub body up top, and left to right the snap ring, inner hub, and spacer

    20200727_182945.jpg

    Spacer goes first; grease where applicable

    20200727_183054.jpg

    20200727_183311.jpg

    Then flip it over to reveal this groove

    20200727_183337.jpg

    Yep, snap ring goes there

    20200727_183544.jpg

    Make sure your shit is in FREE mode

    20200727_183741.jpg

    Finalize your assembly

    20200727_183811.jpg

    Don't forget that new gasket you got in your rebuild kit

    20200727_184247.jpg

    Put on a few bolts, and do a function check by ensuring the inner hub (spinning it on the backside) only spins when in free mode

    20200727_184538.jpg

    20200727_184522.jpg

    And remains stationary when in LOCK mode

    20200727_184518.jpg

    You'll use these gaskets when attaching the assembly to your axle hub on your spindle

    Remains to be seen I bought the tires and wheels the rest came along
    The only time you could have a problem is shifting the transfer case into 4 wheel drive.

    Depending just how the hub was miss assembled .

    Shit bolted onto other shit, and junk.
    No problem with the differential. You merely had one CV spinning and the other stationary. Just switch the LOCK to FREE and you are fine. I would do a complete function check of the system to check everything.

    With both front tires lifted off the ground.

    1. Put both Hubs in FREE to ensure the internal cam is not locking the CV and both wheels spin freely without spining the correspinding CV
    2. Put both Hubs in LOCK and ensure that the internal cam slides inward and locks the connection with both CVs. You should see each CV spin while turning the tires accordingly.
    3. There is no need to mess with the transfer case in this situation, but you can also lower it all to the ground and get offroad to ensure you can lock in your front driveshaft and engage 4WD

    Impressive write-up, well done. I get carried away and suck at taking the time to document with photos.

    Thanks!

    Had forgotten I took those pics some 3+ years ago so I was glad I still had them.

    Would pull them off wrecked trucks and one didn't want to turn at all; turns out the spring had broken inside the dial and so it was stuck.

    For those watching, brass drift is your friend in knocking those cone washers loose
