You didnt waste money on the AVMs they are separate from the wheel bearing assembly and the wheel bearing assemblies cost around $250 a piece depending on where you get them. The AVMs don't have anything to do with the wheel bearing assembly if thats what you're wondering, they replace the vacuum operated hub.
You do not have the TTB, you have the 4x4 SLA. TTB was 97 and older, it stands for twin traction beam and that is NOT what you have on a 99 model truck.
BTW what do you mean by explorer front end swap?
