i have the differential and i need too take the joints that conect the wheels too the differential apart-any ideas?

 

front or rear? model? if its front on a 4x4 I unbolted my left a arms for more room then used a pry bar to pop out the left cv shaft ,then pryed the diff off the right cv shaft (or front drive shaft )it may take a little force but they pop in and out) (and im assuming youve allready unbolted the diff ,and slid it foward to remove the frondrive shaft)
if its a rear diff you need to start on the brake side ,remove the wheel ,then the wheel hub ,then the axle jam nuts ,brake cover ,brake drum ,brake backing plate,now the left wheel ,hub, jam nuts ,the four bolts at the top of the diff then you should be able to slide the diff off the axle then reasamble,the berring behind the brake drum may need replacing as well
