I have 3 Subaru's and have replaced the front half shafts on all 3, no
problem. Now the driver's side haf shaft needs replacement. Pulled
my Chilton manual, which of course does not give me the detail I
need. One of the first steps is says to do is remove the lower
control arm-to-rear housing bolt and nut. I found a picture of this
for a Justy, and it appears they are referring to a long bolt that
passes through two pinched-sleeves. I got the nut off (driver's end)
but no matter what I do, I can't turn the bolt head or drive the bolt
out by putting the nut back on the end of the threads and hitting it
very, very hard.

It seems that I have to remove the entire rear axel in order to get
the half shaft out. I have removed the roll pin (spring pin) from the
transaxel, I have the rear strut nuts and bolts out and it looks like
removing the trailink link and its retaining bolt (Chilton language)
should not be a problem.

Anyone have any experience with driving out or removing the lower
control arm to rear housing bolt. I got on this puppy with a 1/2"
breaker bar with a pipe for extra leverage (nothing). Before I
attempt with my 3/4 drive socket set, I want to make sure I am not
attempting to turn something that is not meant to be turned.

I had a battle with getting that bolt out. I banged on it enough that
I coudl then get an open end wrench in there between teh knuckle and
the bolt head, then pried with that, then put another open end wrnech
in beside that, then pried, and so on and so on. I found some pipe to
slip over the bolt head and sit against the knuckle to pry against
later. It needs to come out a good ways since it is so long. Putting
it back in I used an angle grinder to taper the threaded end.(be
careful to have the nut on it when you do this, the back the nut off
to clean out the threads. I greased that hole up well, then beat the
bolt back in and it wasn't as bad going in as I feared it might be. I
wouldn't want to do it again though.
