Funny, I've got an '03 Edge 2WD that I'm looking to go 4WD with. What's the mileage? Maybe we could swap parts if they're compatible?
You might get the short end of the stick though. If I were you, I'd get the 2WD spindles from a Trailhead or Edge, and a used 2WD ABS pump. Then I'd install those and remove the front drivetrain from the front driveshaft up, leaving the transfer case intact. Parts should run $200-300. Check out Car-Part.com--Used Auto Parts Market
