Default Split front control arm bushing (I think)

Not sure if it's considered a bushing or what, so I'll let the photo speak for itself. This is on an Impreza 2.5GT, which is supposed to be equivalent to a 2008 WRX auto:

(front/passenger side)


Driver's side has that same type of split in the bushing(?). The car has 130k on it, but I haven't really noticed any handling problems lately, only some occasional light popping noise from that that area over small bumps at low speed.

Any advice on how serious this is, and what to replace them with? Thanks

That's deterioration. It's inevitable due to influences of oil and grime picked up off the road as well as exposure to the air / ozone. Rubber is tested for such resistance, but in most cases manufacturers only require these things to last one vehicle lifetime, which is usually considered 100k miles. By years your car isn't old, but by mileage I would expect to start seeing wear like this. Sooner or later those small surface cracks will propagate through the bushing and it'll tear and fail. How quickly that happens depends on the loads your suspension sees. Smooth roads and no crazy track day or autocross and you could get 30k-50k more miles out of it. If you're on rough dirt roads or having fun at a rallycross you could get one big load and tear it apart in 5k miles.

Thanks Scooby921, it certainly looks like rubber which has dry rotted. Are these things a PITA to change out? I've read that it's easier to replace the whole control arm than just the bushing. But I'd prefer the cheapest solution. This is my DD, I don't autocross it.

It's a PITA.

There's aftermarket bushing that require you to gouge out / burn out the old bushing, clean up the sleeve, and (the easy part) grease and press in the urethane bushing.

If you go to the dealer, they will just sell you a new arm with the bushing already in it.

I'm considering new control arms, since they come w/ new front/rear bushings as well as new ball joints. Parts geek has OEM replacements for $282, and I'll need two. Then I'll presumably need an alignment...this is becoming expensive.

this is why I converted my WRX to STI control arms which have a sealed/booted/greased spherical bearing.

When my passenger got a little worse than yours are now, I went ahead and got an OEM bushing and found a small garage who had a press. (Total Cost: Around $70 for part and labor) Having been around when a buddy did his on an E30 and being a fairly straightforward PITA job at times, I was comfortable contracting it out.

It is usually highly recommended to do them in pairs, but I did not, with the plan to swap in polyurethane before too long.

Any issues/problems with the WRX to STI control arm switch or relatively seamless?

It's not seamless. The STi arms are wider.

I swapped in :
2011 WRX front axles
Forester inner tie rods
08-14STI (or 11-14 WRX) sway bar (because it's wider)

Maybe I can buy the bushings (they're $46 at partsgeek), remove the arms myself, and bring just the arms to a shop to swap out the bushings. It should be cheaper that way, since I'm not taking up a lift, and less of a PITA since I don't have to mess with bushing removal.

Decided to buy a whole new control arm, which has both bushings and the ball joint already mounted. I did it this way (instead of replacing just the bushing) to save time...and because I think I would have needed a garage’s help to install just the bushing (need a press). With the assembled part, I can replace it myself.

Parts Geek wanted $282 ea (didn't check shipping)
Parts.com wanted $206 ea + $50 shipping
Fred Beans wanted $224.96 each....then they wouldn’t tell me the shipping charges until after I input my CC information it...as if that will make me more likely to buy from them. When I found out that shipping was $40, I cancelled the order.

The best deal that I found came from Quirk auto, who charged $210 ea + $14 shipping.

BTW, I found this interesting site from a shop that says this is a common problem in later model Subarus, they even have a photo very similar to mine

Update. I took off the driver's side tonight...it was really fun to take out the ball joint. That "split" I spoke of wasn't a split at all, that's the way the bushing is designed. Here is a side by side comparison (new/old):
