Hi Doug, I installed the 1990 Ford Ranger 8.8 rear end and it uses all the stock Volvo 544 suspension parts. Later model Explorers used rear disc brakes but I do not know if the dimensions would be the same as the Ranger. I would "assume" that someone makes an adapter to put disc brakes on the Ranger axle.
Just narrow the rear axle housing on the long side so it will take another short side axle. There was plenty of meat to drill and tap the housing to be able to install the torque rod assembly. If you need any further pictures just post a reply.
Best of luck.
Ray J.
