    Has anyone got experience in replacing lower rear control arms on a 1972 Centurion (B Body)? Looking for hints tips or tricks.

    Put jack stands under the frame in front of the rear wheels. Support the pumpkin with a hydraulic jack, closer to the pinion . Unbolt one control arm at a time, and replace it with the new one. It will help to raise or lower the pumpkin if the holes are hard to match up as you go.

    Hey Larry. Thanks a tonne man. Great advice. I just hope the bolts aren’t seized. Wishful thinking. Lol.

    Larry!!! So after slathering on the penetrant … I went in and lived under my car for a few hours. I have to tell you that the car is now TIGHT! Although I didn’t have new school tools -I managed to get the job done. The poly bushings are magic - despite some protest by a purist. The car drives like a dream. The rear is grounded and the front is a tad sloppy but I think that I’ll be swapping out the front suspension bushings to poly. Thanks again Larry for all your expertise.

    Yes the rear suspension benefits the most from a bushing upgrade due to the length and narrow width of the upper and lower control arms, and like you said, you'll feel the difference:D
    The front control arms not so much, they're pretty rigid pieces of steel just by themselves, so they dont have to rely on stiffer bushings to keep things firm and in place.
    Inspect the front bushings and the complete suspension...... tie rods, idler arm, ball joints, etc.
    I'd replace the front bushings with new rubber ones and any worn hard parts .

    Thanks man. Great advice. Old man winter is around the corner here in these parts - so it may be a spring project. Ride on.
