Went through the rear end of the 99 Outback to fix a few issues and do some preventative maintenance. Put aluminum reservoirs on the struts hoping they'll run a little cooler. Changed the valving, put in new oil, and replaced a boot and the top bearings.
I had a wheel bearing fail last year and I've been putting 20k miles a year on this car so I thought it'd be best to just replace the wheel bearings, seals, and hubs over the winter. Will probably do this every winter if I keep driving the car that much and it keeps them from failing on the road.
That one parking brake shoe was really bad so I replaced all of them. I don't use it much but I think mud and sand get inside the drum and just eat the shoes.
One CV boot was leaking, another one might have been leaking slightly, they were all at least a little cracked, and this one was worn over halfway through, so I replaced them all and repacked the CVs.
I think I've already swapped out the trailing arm on the driver's side but this one on the passenger side was getting bad so I replaced that with a used one. They're $76 from the dealer so I'm thinking about getting a couple of them.
While I had everything apart I figured I should do some body repair. It hadn't really failed completely but was starting to crack again, haven't done anything on this corner for about five years I think. Hard to see from this picture but the seam on the left is separated and the seam at the bottom where the floor meets the strut tower is pulling apart. Also that shiny piece laying on the floor was barely attached to the strut tower so I pulled it off and cleaned up all the rust and sealer.
Welded those two seams and welded that extra sheet back on. Also added a piece of sheet metal to the bottom of that seam by the door (lower left).
Painted to slow the rust.
This is what it looked like in the wheel well after a little cleanup.
Welded some of the seams, then added that big patch. You can see where I welded the extra sheet on the inside penetrating through. Burned/scraped more undercoating off. That big rusty crack on the right is welded on the inside of the car. Hammered for some strut and tire clearance.
Painted.
I've noticed a gasoline smell when I filled up the last couple times. Pretty sure this is the source. I've made these gaskets a couple times now, I think originally from cork and the last time from Buna N which is supposed to stand up to gasoline and alchohol.
They're just shredded. I suppose some of the breakdown may be mechanical but I assume it's mainly chemical. Whatever they made that flap out of on the inside is still holding up great.
Got some flourosilicone from McMaster, expensive but hopefully it'll last more than a couple years.
