- If you are going to spend this much time swapping axles, make sure the axle you are swapping in, is worth this much work. There are weak and strong versions of every axle, so don't assume anything.
- Ideally you want the front axle wider than the rear, so keep this in mind when hunting for axles.
- Front and rear axles should be the same bolt pattern, so make sure whatever axle you are looking at can be converted to whatever bolt pattern you need.
- With some axles it's not possible to get the same exact gear ratio front and rear, you are allowed a 3% difference. So 4.11 in the front and 4.09 in the rear would be fine.
- Bigger is not always better. If you only plan on running 33" to a 35" tire there is no point in swapping in a 14-bolt, as all it will do is drag the ground everywhere.
As for mating the new axle to your driveshaft, some axles will need adapters, some you will just need a conversion u-joint available at most any parts store. Normally in most cases when swapping out to a larger driveshaft, you'll need to have the driveshaft shortened, so double check your driveshaft length. Usually hooking up brake lines and hoses is pretty straight forward, usually no adapters are necessary and it will just hook right up to your factory lines. However if you do need adapters you can get them at any parts store. The final thing to remember is that your master cylinder may not be able to flow enough fluid for larger brakes. However many times people find their stock master cylinder is fine with larger brakes. Some people prefer to install an adjustable proportioning valve, or modify the stock one to get proper braking bias.
