[xj40] removing rear shocks? 92 Sovereign

Hi all

have had the car from new.

converted the rear shocks decades ago to conventional
shocks, and have replaced the rear shocks and springs twice
since.

rear shocks are worn out again.

I never thought I would ever ask such a question…

I undid the lower shock nut, and undid all the upper shock
bolts. The top of the shock/spring assembly is loose from
the body. BUT, bloody hell, I cannot for the life of me get
the lower shock bushing off the mounting bolt even though
the nut is off. I also cannot get the mounting bolt to move
in the suspension member when I put the nut back on and
bash it with a small sledgehammer…

I have sprayed copious amount of penetrant on the lower
shock mounting bolt and bush. I am now at the point where I
have tried a 5 foot long construction wrecking bar behind
the shock body to try and pry the bush loose of the
mounting bolt, and I cannot get the bushing or the shock to
move.

the car has recently sat unused for several months,
outside. It took me half an hour to get the rear wheel off
once the wheel nuts were off, the wheel was ‘‘frozen’’ onto
the wheel hub, took the axle nut cover off, sprayed a lot
of penetrant in, wound up bashing the tire all around to
finally break the wheel loose…

I am stuck, literal and figuratively. I was eyeing the oxy
acetylene torch but figured I had better walk away for a
bit before I get carried away.

so, suggestions as to how to free the shock bush from the
lower mounting?

Thanks

never mind, solved…

Loc Tite Freeze and Release, a 3/4 inch drive 30 mm socket
on a four foot long breaker bar, then a 650 foot pound air
impact gun, finally broke the huge shock mounting bolt
loose in the suspension member, then a large hand sledge
hammer on the nut (cushioned by a hunk of 2 x 4) finally
drove the mounting bolt loose, freeing the shock.

bloody hell…

now to tackle the other side

I have a brand new pair of Sachs rear shocks to fit.
Hopefully I get a decade or so out of them…

Put some copper grease on the shaft when you put it back in, eh!–

both rear shocks off, all four wheels off the car, going to
do front suspension and brakes ‘‘while I am at it’’.

turns out autopartsway.ca shipped me the incorrect Sachs
rear shocks, so re ordering the correct rear shocks, plus
new brakes all the way around, plus front tie rod ends and
various other bits.

seems as the car ages it takes more and more time to work
on just dealing with age and corrosion related issues, this
time around I had a heck of a time just getting each wheel
off, and getting the rear lower shock bolts out was way
more work then it should have been.

I am a very well equipped home hobby mechanic, I have a
four post lift, huge air compressor with an air
distribution system and all the air tools, a parts washer,
bead blasting cabinet, and a lifetimes collection of
mechanics tools. If I was as I used to be as a younger man,
working outside in the dirt with basic hand tools, I think
I would have given up and walked away…

when I need any major parts to keep my XJ 40 running, I
just buy another car and strip it, they seem to be
available around here for $300 - $800. Really a shame
though that the values have sunk so low. I have just gone
through my third parts car. Wonder how much longer we will
see XJ 40’s on the road in regular use?–
