I pulled the shaft, put the whole assembly vertically in my bench vise, taped off any cracks and openings in the torn rubber and poured poly urethane in that vertical position. I had one leak so things got a little messy, but it was slow enough that it cured before too much leaked out.
And a screw driver to steal it too…
I’d say his daughter wants a better riding/handling car with more comforts than any 80’s based EA powered Subaru could offer! I doubt she will get much more involved mechanically than paying a mechanic or buying parts for her dad to maintain the vehicle.
Get that forester issue sorted Steptoe and enjoy it for what it is
Cheers
