Found a 4 door 2001 blazer being parted out locally and i was wondering how difficult it would be to take out the wheel bearings, and obviously put them on my 2 door jimmy?

also will the front bumper and rear bumper end caps fit?

 

They are not all that difficult to get out of there, but you are taking a chance with used components... I really do not think it is worth it to reuse wheel bearings, but if they feel decent when you remove them, I guess you could go for it.

 

I don't think the front wheel bearings will interchange between 2wd and 4wd ,the rear probably will but you must remove diff cover and pull the axles to get them out (make sure both trucks have same type diff ).
