I have developed a sqeak in the rear and I think (hope) its the bushings needing lubrication for the rear swaybar. I power washed the wheel well recently and possibly that's why...

So what size Zerk fitting and what type of grease should I use.

 

Most any grease gun will fit the Zerk....
I would use a waterproof BLUE synthetic or maybe a RED if that is what came in the gun....
IMO just by a MINI (small) grease gun (unless you have a need to do lots of fittings)...and good to go!!

 

Hotchkis sells a special grease for urethane bushings:

This is a clear, silicone based grease that keeps urethane bushings from squeaking/deteriorating. I NEVER use petroleum grease on urethane bushings.
