I've had a ripped steering rack boot for the past 2 years, and i'm uh finally ready to fix it :icon_redf One useful tip I've gathered so far is to count the tie rod threads so I can reinstall it exactly the same, but my question is what the boot is supposed to do in the first place. Is it just a dust cover for the steering linkage? Is it supposed to contain grease or other creamy lube filling like a CV joint? Considering 2 years of dirt has gotten in there, is there anything I should do besides a quick cleaning to make sure no problems pop up because of this?
