2002 F-150 Rear End Swap Question

Hello all

I need to get my 2002 F150 XL out of my driveway but has the famous blown up 8.8 rear end.

Can I by a 97 to 99 drum brake truck and swap the disks from the blown axle and put the earlier rear in the 2002?

You can't swap disc to drum or drum to disc between the units.
You know one uses calipers and the other uses backing plates and shoes.
A problem is, you mix non stock system parts like this and your brake bias/balance between front and rear goes out the window.
Said another way, line pressure to the rear brakes is different between the two types as controlled by a pressure regulator at the master cylinder.
For example if the rear gets to much pressure, they lock up before the fronts do their share and vic vesa.
Then there's ABS to have an issue with from any imbalance.
The 8.8 has been around since the mid 80s and still being used.
I wouldn't say it's famous for any issue used in a stock application for which it is meant.
Go putting big tires on and running through the woods, it might give a problem at times.
Repair what you have if it is only the internals and be done with it and the hassle.
Good luck.

What is blown up? I have rebuilt a couple 8.8's I have owned....not very complex.

I think the OP is asking if he can buy a drum brake rear end and swap the disk setup from his original rear end onto it, thereby maintaining the stock braking setup.
