PS Rack Rebuild - Correct Lubrication?
I’ve taken my power steering rack apart for a clean and reseal…and am guessing that a lithium based moly grease will be appropriate for re-greasing the geared portion of the rack shaft plus the lower tower needle bearing race (in other words, those areas from which I’ve cleaned the existing old grease), while I will pre lubricate the middle of tower bearings (along with seals) with ATF. Is this correct?
My general concern is the extent to which the heavier moly grease might intermix with the ATF present in this system, but my further thought is that the various seals are designed to sequester the ATF away from both the rack shaft and lower tower bearings. Does this sound correct?
