    :) What can I do to get all those years worth of gunk, debris, and grease off my LCA's I am going to put in new bushings and ball joints and I's like to paint them nicely.

    What is a good cleaner to spray on? Engine Brite I have already sprayed on the went to try to power blast them but not much came off.....

    How should I get out the old bushings and joints?

    a heavy duty scraper and lot of work. soak em for a couple days in soapy water will help. If its undercoating a torch will help soften it up.

    There are you tube videos of how to remove and install bushings and ball joints.
    here's one...on a second gen f-body even!!

    Oven cleaner will help remove the grease and general grunge.
    It will soften undercoating only slightly but enough to scrape off to clean with solvent

    Once they are off hot tank them at the friendly engine builders shop. An overnite dunk willl do the job. pre BJ and bushing installation.

    Here are the steps I do my grimy parts before paint

    1. Oven Cleaner or Engine Degreaser in the can, soaking for a few hours or so

    2. Power wash the part

    3. If there is any tar or heavy grime left I try to scrape it first

    4. If it's too thick, I hit it with a wire wheel on a hand held grinder..it's messy but will break the tar/grime down

    6. Power wash again, let dry

    7. Then sandblast the part to bare metal, this will remove paint and light grime or tar still left

    It may or may not be correct, but works for me :cool:

    How I do it.
    Oven cleaner
    power wash
    Then i use electrolysis to clean all the rust off. Basically I dunk them in a water/washing soda bath with a battery charger hooked to them over night.
    Power wash/light brush any left over scale.
    Dry
    Paint

    I remove old bushing/ball joints with an air hammer/chisel. 10-15 seconds a piece and they are out. Old mechanic friend showed me this one.

    I just used an electric drill and a zizz wheel( or wire brush wheel)
    check out my link to see how mine turned out.

    You dont have to get it down to bare metal just get all the dirt and grime off
