I guess my biggest question is is there any modifications that have to be done to the dana 60 in the front or the 14 bolt f f in the rear? or do they just boat ride up to what is already there?
Dana 60 front is straight bolt up. Here's the but...... if your upgrading to a d60 your planning on lifting the truck and putting on larger tires, so upgrading to crossover steering is almost a must (stock steering on a lifted truck SUCKS). If you do crossover you also have to remove the sway bar. Your wheels will have to be 16's or larger. You can run 15's, but.....A LOT of grinding and careful selection of offset is required. Driveshaft will have to be modified, shortened a little and a different yolk (takes a different u-joint).
Now for the 14b...... 1ton you'll have to cut off the spring perches and move them.You will also have to move the shock mounts and mod driveshaft (shorten and change yolk) If the 14b is from a 3/4 ton it's straight bolt up affair except for the driveshaft mods.
Once the axles are in you will need to change to a one ton master cylinder because the stock one doesn't move enough fluid to give a good pedal feel and stopping power.
All of this is also dependent on the year of your truck and the year of the donor axles. The brakes may or may not just bolt up. The later brakes are metric and the early are standard, so if you mix years the brake lines won't interchange.
So in short.....NOT a straight bolt in, if done right.
Depending on how you plan on using your truck and what tire you'll be running, a 3/4 ton axle swap may be a better idea. If done from the same year as your truck it's a bolt in, only driveshaft mods in the rear.
The drawback to a 3/4 ton swap is the front axles are the same strength as 1/2 ton just with better brakes and 8 lug outers.
Edit....... Damn I must type slow nvrenuf beat me to it
