Drum to Disc

I have a 97 f-150 lariat with drum brakes in the back and i was wondering if anyone knew how to or if it could be done, but i would like to switch it out the drums for disc. The only reason why im considering is because my rear end has gone out and I have to buy a new one for it and the place I'm looking at has one out of a 97 and one out of 2000(with disc) so if it was possible i would like to switch. Any help would be appreciated. thanks

It CAN be done because I bought the rear end and master cylinder from a guy that did the swap. Just get everything that's different from the "new" rear end donor. That may include parking brake cables( which should come on the rear end ), proportioning valve, master cylinder .......

It should, I got disks from a guy who swapped a 99 disk to a 98 drum. Unfortunately the Bearings are larger on the disk and the back plate mounting is different so I can't just bolt on the disks. But the lines and emerg cables and mounts are the same for 99 to 98. I am sure someone hear will have better details.

oh, since the 2000 has a higher load rating (larger wheel bearings) technically the truck capacity will increase to match the new axle.

Your 97 wheels may not fit over the larger studs of a 2000. I don't know for sure. The 97 is 12mm and the 2000 should be 14mm. The bolt pattern is the same though. If they do fit, you will need the lugnuts from the 2000 on the rear.

I would keep driving it. My front would pop even after the ball joints where replaced. Some have mentioned checking the pinion.

How much side to side play do you have? Usually when something goes bad in the rear end seals start leaking.
