I'd begin by cleaning it all well before taking anything apart, I use the purple degreaser suggested by Rich some time ago, it's very gentle to paint and rubber/plastic parts .

Certainly NO BRAKE CLEANER .

Consider trying the dilute DAWN dish soap in a spray bottle, I dilute the purple stuff three parts water to one part purple cleaner, SAMS CLUB employees typically have no knowledge of this product even when I bring in the empty jug with stock number on it...

It's in the office supply section of the SAMS near S.W.M.B.O.'s house .

Spray bottles from the .99 cents only store ~ I bought some nifty looking ones from COSTCO and discovered they're _worthless_ for anything containing soap ~ the top falls right off the filled bottle, no way to make it stay in place, money wasted .

Try to have all the parts in hand when you begin and print out at least two copies of that image, one to take under the car and scribble notes on and get filthy & oily, "cheat sheets" are a wonderus thing but only if you remember to make them first .

The bushings proper are nylon and so don't require lubrication, if you insist, use aerosol silicone .

Take and share some pictures before, during and after , we like to see how and it was before cleaning and touching .
