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.

“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 ↗
“I thought I needed to push the axle all the way through the hub so I cranked the axle puller all the way down and now the end of the axle is wedged very tightly against the side of the wheel hub and I can't get any part of it to move.”source ↗
“I tried to remove the knuckle from the upper ball joint to get some wiggle room but I think the axle is wedged in there tightly enough that I can't quite get the knuckle off.”source ↗
“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 ↗
“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 all”source ↗
