I have a question, a frield of mine says I should convert my impreza drumb brakes to the legacy rears.. however dont you need to convert to AWD first?

I think you just need parts from a front-wheel-drive Legacy.

Yeah, you probably want to convert. Would be easiest to find a thrashed FWD Legacy (assuming your Impreza is FWD) and then just loot that car.

So if I later wanted to Go AWD I would have to swap the Rear discs again?

So these Rear disc has to come from a FWD legacy?

I believe the discs are the same, but you may have to get the rear spindles from the Legacy. I don't know if the drum brakes use the same spindle as a disc set up. It would certainly be easier with the ages-old bolts and junk on the spindles you'd otherwise have to disassemble. AWD spindles are different (they have an axle going through them, for one thing).

I thought this would be easy

I suppose you could get rear legacy/impreza AWD spindles and suspension and discs, and then later put in the transmission and diff.

You might also need the crossmember, lateral links, and trailing links.

or just sell it and buy an AWD, 4 wheel disc Subaru.

[Shameless plug] 1-3-2-4, I have my old, though still good, rear discs, calipers, and brand new pads from my FWD that you can have cheap ($45+ship) if you decide you want to do this.[/Shameless plug]

I know this conversion does get done by other people so it can't be that bad. You should probably roll over to NASOIC and check out what they have done. There are a lot more Impreza guys over there who should be able to answer your question.

NASOIC is ok.. But I call NASOIC = a play to ask questions but to get jokes with anwsers

Where here at Legacycental you get a Strightforward Anwser with hardly any BS added to it.

Which is why I ask some of my impreza questions here.

I was going to try and locate a FWD to pull the stuff from.


From what I understand I need the Whole kuckle correct? I was going to go with a friend to help pull some parts in the sometime Spring.

yes, you need the whole knuckle

but i can use AWD legacy rear discs?

yes, same goes for the calipers.

thanks Josh your my Hero!!

lol I've never seen a FWD Legacy before.

looks like the knuckle will need to come off with a breaker bar?

Just guessing here looking at my own Rear..

Other then just swapping the Wheel hubs anything else major that I might overlook.. seems pretty stright forward.

I'd get a big breaker bar and a pipe to put over it, some good penetrating fluid (might even want to hit it the day before), and a hammer. If you get stuck, try tensioning the bar on the bolts and rapidly hit the end of the handle in the direction you want to go with the hammer. It's the rapid hitting that works better than powerful sharp strikes (and is safer). A sawzall would be nice, too, if that damn trailing arm just doesn't want to give and you just need to get the damn thing out of the junk yard. That's a worst case and hopefully you won't have that much trouble. If you could get an air impact gun at it, that would be sweet, but I found the 18V Dewalt to be seriously lacking for such a task.

Something no one brought up is, what about the brake bias?

Thing is I'm going to be going to a U-pull it yard to get these parts, so I will bring the PB BLaster, I have a 10" Breaker 1/2 bar so that should come in handy.
