Adding Zerk / grease fittings to swing arm pivot, by SystemTechRacing

Less friction means smooth plush suspension. Adding grease fittings to swing arm pivot. I gotta tell ya, pumped in grease to the assembly seems to do a better job than just packing the bearings. A one minute job to lube this pivot now.

It's important to have an 'exit' hole for the Grease.
When you're pumping fresh grease in, the old, dirty, contaminated grease has to go somewhere.
Even a mediocre Grease Gun can generate pressures of around 500psi or higher, without an exit hole, you'll pop the Seals out of place.
Exit hole only needs to be around 1mm diameter or so, and drilled diagonally opposite the Nipple, so the fresh Grease travels over as much of the Bearing's surfaces as possible.
The Grease in the hole will dry out to form a plug, stopping any water or other contaminants getting in.

Thank you. Great video. I’m installing Zerts to my 07 FJ upper control arms. Stock arms, new bushing will now be serviceable.👍

So how has that been working for you. Aside from the possibility of it getting knocked off on the bottom I imagine it would be working great?

My dad use to use a flush tapered Philips head recessed into the axel then he could remove it and thread in a zirc, pack with grease then replace the Philips

Incredibly informative!  Great work, thanks.

usually grease fittings are installed on 'non sealed' wear surfaces, but i guess this is a great way to pack them with grease after the seals are pressed in

My yamaha wr 500 linkage and swing arm bolts are hallow. Going to pack the grease in there and add a hole in it at the needle bearing collars that pivot works added holes to.

Have you thought about Trying a needle zert flush fitting?
