CV axle threads

I am getting ready to replace a wheel bearing but the threads are damaged keeping me from removing the spindle nut. Yay for buying used...anyhow does anyone here have any tips on how to proceed. It appears who ever did the last bearing change used a metal hammer and hit the threads pinching three threads into a lump near the end of the cv axle. Thanks in advance.

 

You got any pics?

 

a very small file, and file them to a point where they are usable, or purchase a proper thread chaser

 

No pics yet had to stop and put her back together for the work week. I dont think a file will do much because the end of the axle is not round anymore. The area impacted sticks out a bit. I'm almost thinking I need to either grind it down or try and cut it off since the spindle nut will come about 3/4 of the way to the end of the threads but I dont know that a sawsall with a demo/steel blade can handle that.

 

subbed to see the outcome
good luck OP

 

Get an angle grinder and cut off the nut.

 

Luckily the axle half is only 60 bucks so worst case I'll take scuba's advice and cut the nut and replace the axle. I'll snap some pics and post when the horror is over. thanks for the suggestions all.

 

Yeah I'd just either grind down the offensive area, or cut the entire end of the shaft off.

 

It's a hard to snap a good shot that shows the three threads pinched but from this angle you can see the spot impacted. Today I ground about two or three sixteenths of an inch off the end (picture was taken before grinding) but had to do so quickly at work and put it all back together. (no electricity to the carport at my apartment complex) So now shes ready for another attempt to get the nut off. If it weren't for my job this would be done lol. I'll post with my next success/defeat.

 

go buy a metric thread file... they do wonders for shit like that

 

This. It doesn't look too bad from the picture. A little elbow grease should get that cleaned up... and you won't have to buy an axle.

 

Well after grinding off all the mashed threads I used a file to fix the last thread at the end and problem solved. After all that changing the bearing was a breeze.
