Teeners
I have finally gotten around to hooking up the anti-sway bar using 914Rubber plastic inserts (bushings?). When we drive the car there is thumping noise within the rear that started once we had the anti-sway bar connected. I made sure all of the connections are tight and not stripped. Might the rubber mounting brackets need grease? I am thinking that this might be a binding a then release event that is creating the noise? Any thoughts or direction? |

is it a stock rear sway bar?
how low is the car it sounds overly simplified... but its not too hard to put that bar on upside down can you look under the car and move the rear suspension through range of motion to see if the bar is (upside down) and hitting the trunk floor |

I will look, make certain I am not the victim of the PO playing with this part of the car. |

You may have it upside down. That would make the bar hit the trunk floor under compression.

*******UPDATE********
Got under the car on Sunday, it seems that there is a little bit of play within the new bushings. perhaps as much as 1/4 inch. I will buy another set (had to man-handle them until I was able to get them attached) since I now know how to do this. The little bit of play makes a minor thump which is then amplified through the torsion bar and then the trunk. Sound horrible. Will update as I continue through this tortured torsion. |

Tried replacing my bushings this afternoon; a little bit of play, but then they are the original 46 yr-old ones. Bolts are frozen and I'm too scared to try harder (AMHIK). Not urgent so will wait until next time I take it in to mechanic, and get the fronts done at the same time.
