squeaky sway bar bushings

Recently replaced the sway bar link bushings on my 1995 Honda Accord
and after the first rain with them they really squeak a lot. Should i
have put oil/lube on them while installing or are they not tight
enough? I tightened the top nut down just as much as the old ones
were. Any help? thanks.

 

are they oem rubber or aftermarket urethane?

 

You're using aftermarket urethane bushings. You need to put _silicone_
grease on them before installation and be prepared to pull them apart and
regrease once in a while.

Or you can install OEM and forget about them.
