What is wrong with the pistons? Are they really the weakest component in the rotating assembly? Just asking. -
I agree that this precaution is important when dealing with a rusted pin of unknown origin. My experience with OE stainless pins has been that they come out without a fight. Of course if the OP can wait for obtaining proper tools, they should order the axle pin remover, or at least a plain 7/32 punch (not available in hardware stores). I thought that on a 6 mm hole, a 7/32 drill was easier to use than a 3/16 punch (tried both).

I just tried the following and it worked. Disclaimer: The procedure, as tested, applies to axles that are held with a roll pin to the differential output stub shaft. I don't know if there will be sufficient room to perform it with pin-less axles, but there's always hope. Axle removal procedure: Wheels pointing straight, front end lifted and safely supported, axle nut & roll pin removed. Disconnect sway bar link from the control arm (12 mm head, M8 bolt and nut), and the control arm from the cross-member at the forward mount (17 mm head, M12). Under the hood: if working on the right side, disconnect air intake duct and move it out of the way so that there is a clear view of the inner CV joint (DOJ) housing. Disconnect PCV/vacuum hoses to move the duct, as needed. Stuff something into the throttle body. If working on the left side, you may need to move the washer bottle. My hands-on experience, as of this writing, is only with the RH axle. Hook one end of a bungee cord to the axle shaft near the DOJ, and the other end to a suitable hole in the hood reinforcement, somewhere near the top. The idea is to support the weight of the axle shaft after it is disconnected from the stub. Depending on the length and stiffness of the cords available to you, you may need to find a right combination by connecting them in sequence and/or in parallel. The key step: Pulling the knuckle outwards, slide the DOJ off the stub shaft and direct it upwards and to the rear, to the area where the front differential housing tapers down towards the transmission (MT or AT). The cord should be adjusted to hold the shaft in that position. This, together with the unbolted control arm, provides enough clearance to slide the other end of the axle out of the wheel hub. Done. Installation is reverse. As always, remember to load the suspension with the car's weight before fully torquing the control arm and the sway bar link.

I did have to fix the window washer hose (even before I had to fix the wires). In my case, it was squished and hardened at the bend, blocking the flow. Fixed it by splicing in a new piece with two connectors. If you can't reach the broken end, you will need to remove the pillar trim. For repair, use a thick-walled vacuum hose.

I know this won't help, but anyway. After this code came up on my '95 Impreza, I bought a new front oxygen sensor. Then, when I situated myself underneath the car, I found the flexible joint after the converters to be rusted out and leaking. I fixed the joint and replaced the sensor, and the code did go away. I believe that the problem must still be somewhere in the feedback loop of the catalyst monitor. It might be using inputs from other sensors and there could be something wrong with one of them (w/o any extra codes). Reminds me of the posts about frustrating EGR codes where MAP sensor was found to be the culprit. -
I replaced a rusted-off converter flange with a hinged replacement, the better kind that is made of stacked plates. It is held by the remaining weld bead from the original flange. Since the hole spacing is different between the new flange and that on the intermediate pipe, had to use a pair of stainless J-bolts, combined with original springs.

Caliper question
avk replied to SUBARU3's topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX
One thing that might be different between Legacy and Impreza calipers is the diameter of the piston. -
If FWD MT existed, and I believe it was, there has to be a rear cover that would interchange with tail housing, just like on auto transmissions. But then you might have to remove the transfer gear from the output shaft if it's removable, or replace the shaft with FWD type, at which point it would be easier to simply swap the whole thing.
