I hope this hasn't been covered somewhere before, I cant seem to find it if it has. But basically my o/s shock is leaking its the old oil type. I have replacments and when the garage went to change them they said that its all one unit including hub is this correct? the ones i bought specifically for my car dont fit they're just inserts but seem to thin to fit in the shock housing. Do i need to buy a new assembly including a hub or are they missing something on how to remove the shocks?
