I have written about the best method for removal of the outer cv bolts in
previous posts, but here's the short version again;
1. Loosen the outer 46mm axle nut(s). (you do not have to put the van on
jackstands; drive-up ramps would be better if you're bigger than I am (and
I'm kind of big!)
2. Remove all of the inner cv bolts.
3. Bring the axle/ inner cv(s) off the flange(s) and gently let them hang
down. Cover each cv with a large ziploc baggy closed around the axleshaft
with a tie-wrap or a short twist of wire to keep the mess contained and the
dirt out.
4. Slide the outer cv(s)/ axle stubs inwards; out of the bearings.
5. Remove the now easily-accessible outer cv bolts, using vice-grips to
hold onto one bolt head while you loosen the other ones. Do NOT clamp the
axle in a benchvise or with pliers or a vise-grips, it'll cause surface
damage that will lead to failure. ON the last bolt, move the vice grips to
one of the loosened bolts to break torque on the last bolt.
This gives you the ability to properly clean the dirt, mud, grease. etc. out
of the hex or 12-point holes with a pick or piece of wire, before trying to
insert the appropriate tool and break torque on the fastener. I always tap
the 6- or 12-pt bit 'home' inside the bolt recess before applying force.
This method has worked for me for many years with a 100% success rate. Any
other methods I have tried have only resulted in stripped-out bolts.........
YMMV,
Mike B.
