Default 2002 wrx front subframe removal

Hey guys has any changed out their front subframe? the stealership wants a fortune to do it. The main thing I'm afraid of breaking a bolt off. Any help would be appreciated.

I don't think you are strong enough to break a bolt off unless they are completely rusted. Bolts on the subframe are pretty large.

Like scotty said use some sort of penetrating oil, some of the bolts can be accessed from above the subframe, allowing you to spray the threads letting the oil work its way down into the threads.

The bolts are mostly large and you would need a huge breaker bar to snap them, its highly unlikely they will break after letting them soak in liquid wrench.

The subframe gets rusted out pretty bad in the snow belt.

If a bolt breaks off, you use an EZ-OUT and re-tap / chase the hole while you drive around without a subframe for a while while your stainless bolts ship in from Fastenal. Then you install them with anti-seize so that doesn't happen again... Even paying for the EZ-OUT, taps and stainless bolts... it's cheaper than the dealer AND next time you'll actually be able to remove the bolts.

Yeah, and if you manage to break one off the dealer would have broken it too. Then charged you more to replace it.

It is a pretty straight forward removal. You will need a 12mm,14mm and 19mm. If it is the first time they have been off you will likely need a breaker bar or impact to get them off.

I hate cars from the east but when I do work on them its time for the penetrating oil. Give it plenty of time to work before you try to remove the bolts. Good luck on that.
