as long as it is a non-disconnect axle, cause if it is then you need to change the axle seal on the passenger side, otherwise you will get blow-by

he said its from a 1998 so that means non-disco, and means the shafts will run the spicer 297x u joints which can be supplemented with the spicer 760xu joint, which is larger bodied and stronger.

yeah, but don't change the joints until you need to. the 297's are fine for now, unless they are worn out. then yeah, try to get the 760's for replacement.
