Pushed CV axle in while changing brake rotors

Using a gear puller or heavy hammer to remove a rusted brake rotor can accidentally push the CV axle inward through the wheel hub or separate its inner joint. This halts the repair job, risks spilling transmission fluid, and often forces a costly axle replacement.

What people tried

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    using a gear puller to force off a stuck rotor
  2. 2
    pushing the axle back through from behind to re-engage the splines
  3. 3
    replacing the damaged CV axle component
  4. 4
    Using a larger sledgehammer to strike the spline directly

the rotor WOULD NOT come off. multiple people with torches, increasingly large hammers and plenty of experience with brakes tried and walked away humbled.source ↗

so when using the puller, the part colored in red was pushed back.source ↗

Trying to replace the driver's side wheal hub on a 2004 Buick LeSabre and I've never seen one this stuck. The CV axle shaft absolutely will not budge. We've tried, prying, hammering, and heat and have gotten zero movement whatsoever.source ↗

We hit it with a 20 pound sledge and it didn't move at allsource ↗

Front right lower control arm randomly snapped while going pretty slowly. CV axle pulled out of the transmission and oil leaked everywhere.source ↗

I pulled outwards to check if it was in fully, and I ended up pulling pretty hard on it. It came apart at the inner joint, leaving part of the axle stuck inside.source ↗

I'm kind of annoyed I have to spend another 200 bucks too, but I guess it's a good idea to replace anyway.source ↗
