So i went to replace my water pump today and the guy asked me what size my hub height is. Anyone know this? I have no clue
I have a 1990 jeep cherokee laredo 4.0 4 door

Not sure maybe this helps

i think what hes tryin to say , god bless the parts man for he knows not what he says, is do you have a serpitine belt or a v belt. i imagine the v belt water pump hub could be different. tell him what you got. call around too. it never hurts. i call 3 different part stores at least 20 times a day.
