Adding Zerk fittings

These are some pics I've taken of one of my Miatas with zerks added. You don't have to do it this way, just suggested locations. Zerks are not absolutely neccesary. They will allow you to maintain lowest possible friction in the suspension action over time. If you run out of the Hyperlube the bushings come with, I recommend Superlube , Ace Hardware carries it too. I used 6mm threaded zerks. 1/4"e; threaded zerks also work but there are a few differnt types of grease fitings that will do the job.

Drill the control arm, deburr, tap. Voila! Take care to locate the zerk at the exact spot where the two halves of the bushings meet so injected grease fills the .050"e; space between them. For the one piece bushings, remove the steel sleeve, locate the drill in the hole you just made in the control arm then drill all the way through the bushing.

The rear upper inner (R_U_I) only has enough room for a zerk with droop travel less than OE. So check your RUI with dampers installed at full droop before you pull it all apart. The Energy Suspension bushings are two piece, fairly easy to remove for periodic lubing. For lowest friction and best suspension action, I recommend lubing once a year in most climates, or twice a year in you drive the car in really wet climates.
