on my front axle in a 84 s10 blazer 4x4 the drivers side is leaking. without taking the axle completely apart to do the outer seal. or am i sol and just need to drop it and put new seals in it

 

What seal is leaking, the axle or the differential seal? Either way that axles coming out, its not too tough to do though, you maybe have to but an axle nut socket though, 32-36MM, Im not sure on the size.

 

ok thats what i thought i have a front bushing that is completely gone so i have been needing to do some work to it i wish i was closer to having my stuff ready for the sas so i could just rip it all out and leave it out but i will just fix it. is it possible to weld the front spider gears up. but it not bind up when i am in 2wd???
