Step 1: Obtaining and disassembling your Kia Sportage Axle
The absolute first thing you need to find is a Kia Sportage third member from the front differential. They are a common vehicle, so if your lucky a local yard should have one. Typically, they will just pull the entire front axle. Its not a large piece, but still nothing you want to stuff on your motorcycle to get home. Just make sure you dump the diff fluid out. Its should consist of an aluminum axle housing and a cast iron third member. See Picture below:
Once you get your Kia axle home you can start to remove the 3rd member. I recommend laying out some cardboard or plastic to catch any diff fluid that will come out. First, remove the 4 bolts holding the long side axle in. Use your hammer and give the axle some taps until it breaks free. Then slide the axle out. Add it to the scrap pile or sell it or place it on your coffee table as a conversation piece. They choice is yours, but from here on out, you don't need it.
From here you can start removing the 3rd member from the aluminum housing. Two of the bolts holding the 3rd member in are 12mm. Rest are 14mm. Save all of these bolts as you will reuse them later.
Will the bolts removed, again use the hammer to break the 3rd member free. Once free, lift the piece out of the housing. You should now have an empty axle housings and a 3rd member. See pictures below.
