CV Axle separates from hub

[Eyedaho]

I'd have to see a pic of the clip 'In place' on the CV axle to accept that the CV is that far out of the back side of the hub. Me thinks....the clip has popped off. Removing the dust cap would tell the tale.

That makes sense. I was thinking the before/after photos were immediately after install, but it makes more sense that it popped back off after driving.

You right again. They just put it on though. Snap ring (e width) doesn’t look compromised from excessive force

I would think:

1. snap ring isn't fully seated in the cv groove (snap ring is too thick and/or cv isn't being pulled out hard/far enough)
1b. I couldn't get my new cv pulled far enough to seat the CV into the hub nor the snap ring in the groove and the problem was the little flange on the cv got bent in shipping, I had to take some pliers and go around the flange and straighten it out/create more space before it would fully set.
2. groove is rounded off on the cv (if so, might be able to file the groove to a more square angle)
3. snap ring has been re-used, has yielded and is now either out of round or the diameter is too large and it slips over the groove

Try a new snap ring and make sure the CVs snap ring groove has a good sharp lip. This should not be an issue if they are in good shape.

I think it’s one, cv is brand new as of 1/22 and snap ring was brand new, may need the thinner one

Snap ring is oddly beat up, looks like they tried to pound it into the groove...coming from someone who tried to pound a snap ring into a groove, I've seen that before.

Yep,

I, an entry level DIY'er, can confirm this is the way to go. Also get snap-ring pliers from Amazon or Harbor Freight, a bolt (10mm? 12mm??) to thread in to the hole in the outside end of your axle, vise grips and a block of 2X4 wood to set up for leverage to pull your axle outward while holding said bolt, and you should be good to go. Many great videos on front bearings replacement on the 100s start with the R&R of dust cap, snap-ring, etc. You will also want a feeler guage to check for < 0.20mm gap between snapclip and flange.

Yes, those are the pliers you want. They work great!

My bet: Snap ring not seated in the axle groove during last service. And or axle groove has rounded.

I've concerns with the look here. Picture lighting and resolution, makes a very difficult call. Regardless it will need clean up. Proper snap ring gap keeps seal seated properly. To wide a gap, and seal can be compromised.

The seal surface on outer CV between it and knuckle seals, should be silver. I see dark color on axle, and rust on seal area. Where axle penetrates knuckle, we should see brass bushing. The color is wrong, which could be bad photo lighting and or dirt. But we should see grooves of bushing, again bad lighting.

The color of axle should be silver where needle bearing rides. This one after cleaning gave clues as to health of needle bearing.

New brass bushing & axle needle bearing. (Knuckle seal not yet installed.)

New knuckle seal and all greased up ready to install.

I've once, in well over a 100 wheel bearing services, found the E (2.2mm factory installed size) snap, will achieve proper gap of less than 0.20mm. Even when I replace brass bushing, wheel bearings, hub flange and FDS (all OEM), I do not use the factory E size. I use a lot of 2.4mm snap rings and never every anything less than a 2.2mm. But if brass bushing missing, 2.8mm snap will not close the gap to spec. If brass very worn down, a 2.8mm may be needed

At minimum you'll need to clean brass bushing and needle bearing and reseal knuckle,. Likely need new axle needle bearing & brass bushing and new seal.

It's also important to not spread the snap more than need during install. Or it will stretch and will fit loosely (not tightly clamp around axle). It's just as important to have a good groove for snap to fit in on the axle. The groove needs a nice sharp 90 degree (squared angle).

So I tried to make my own puller tool today to get the snap ring back on. I used 1.25 by 2 wood instead of the steel Square stock. I put the bolt in the threaded cv hole deep enough that it broke wood twice. It pulled it through really nice until it wouldn’t pull it anymore and turning it was starting to turn the wheel a bit. In had it on the jack with wheel up.

I retried the size e clip that was new that they had put on and slid into the grease car. It wasnt going on all the way. Then I grabbed the next smaller one and put it on and it fit all way. I’m still not confident that that clip is the right size and that the cv is all monkey up from play. Dropping it off at the ship tomorrow for them to double check what’s going on with it

The fact the E snap ring did not fit, strengths my bet: "Snap ring not seated in the axle groove during last service".

If you did get axle pulled out tight, and had to use next size smaller snap ring. Which is F a 2.0mm thickness, and gap was less than 0.20mm. I suspect you've other issues.

All of which, points to tech/shop that did your service. Didn't have a clue and did not follow FSM procedure.
