Most of the bearings on the Volvos were sealed style inside the housings. If you have an inline engine there is only 1 bearing. If you have a V 8 then there are 2 bearings. You can remove the brass fitting and replace it with a Zerk style but it may be a waste of time. Replace the drive shaft bellows and those bearings will last a long time as long as water does not get to the bearings. EN2 Nunez. IWO JIMA LPH2, SEDGWICK COUNTY LST 1123
