Changing Wiper Pivot Seals
first check the pivots for excessive play before beginning. Up and down is ok side to side should be very minimal to zero. If they check out ok then proceed to doing the reseal. If not find good replacements before starting. they are kind of a ***** to remove but once out it is easy.
the bolts that hold the pivots in place appear to be a self locking type and are hard to remove, spray them down and let the soak with PB blaster, WD-40 etc.. I use a 3/8 impact and a good snap on flank drive socket, do not use a junk socket to remove the bolts they are tight and can ring the heads off easy! Second, take your time if doing by hand removal generates heat and the studs are old. Don't break a stud or your F'ed.
There are two kits that I have seen one as pictured above with the zerk fittings and one like the factory one without them. They need to be drilled out to accept them. Having them is an advantage as they can now be lubed to both seal moisture out and lube the shafts for quieter operation. It is a matter of choice and price as to which way you want to go..
The instructions are posted above, but put the strip caulk in the freezer for an hour prior to doing them it allows them to separate from the plastic packing with ease. install the paper gasket, then the caulk over that as pictured. He made a tool to install the rubber grommet but you can use a socket also and force it over the shaft. re-install in reverse order as removal. Enjoy your dry feet =)
