dont use a metal hammer when reinstalling cv joints onto axel

because ??
 

;)

use an air chisel instead?

lol. DIY gone bad?

you can, you just have to be very careful....
 

I've used my BFH many times..

well i was being verry carefull
 

and i sort of pig nosed the end of the joint that goes into the hub .. but i was able to file it down and back the way it was supposta be and got it to go in smothly again... argh.. i got a different hammer now for the other side and when i do my a4..its got to be really soft metal i am not that strong.. there was this lip that blocked it..argh.. but its all good now..

first off its not funny.. but i modified it to work..:)

haha.. not

its really really bad..
 

unless your as creative as i am to think of reshaping the grooves in the joint to make them fit back int othe hub.

Well you have to line up the joint properly first!
 

My BFH is a splitting maul, which has a very rounded hammer end.. you don't need to hit it hard, just enough to get to climb over the C clip..
