Screwed up my axle joint threads
 

While doing a boot replacement on my drivers side front outer boot, I managed to bang up the threads on the joint. Took several blows with two sledges to get the thing out of the hub.

called around and couldn't find a machine shop that has the capability to re-thread this bad boy.

Just the first few threads are messed up, the remaing 75% is still good.

Any advice to re-thread?

apparently this is a M27x1.75, correct?

would like to fix this issue, but buying a new cv joint is not out of the question.

any thoughts?

How bad are the threads?

outermost 2-3 threads are messed up. the rest is good.

looks like the sledge blows compressed the starting thread.

not sure if I need a thread chaser, or a thread file.

Can you crank out the threads to ghetto re-tap using the old axle nut? This is why i use a puller to pull the axle back through the hub instead of banging on the stub lol

not sure how to ghetto re-tap. any advice?

gonna order a thread file in 1.75 and get to work.

learned my lesson, and the other side was done in 30min.

now I'm stuck with a fresh booted side, and a no-go on the other side.

The lesson learn is to put back on the nut before hitting the axle with a sledgehammer.

If it is just the first thread or two, you can get a dremel and dremel the thread down so the nut can go back on the axle.

yeah, that's what I did with the passenger side, and it worked like a charm.

this job could've been done by now.

funny thing is, I kept reading that the nut should be left on when pounding the axle out.

Yes that is the proper way!!

Fir future readers, once the nut is loosened, leave it flush with the end of the axle before using a hammer.
Better to use a gear puller to push the axle inward.

This. :iagree:

I give the thread/nut/spline area a light spray of PB Blaster during each tire rotation (7.5k miles). This is a preventive maintenance step to make removal easier.

Also, reassemble with a light coat of Weicon or copper base anti-seize on the spline (keeps moisture out).

success!

took a thread file to it for about an hour and after running the axle nut on and off a few times, it seems that we're back in business.

lesson learned.

for those who F$%K this up, the joint has an M27x1.5 thread.
