Default 1979 Trans Am Control Arm Restoration

In the midst of restoring the front suspension components and put together the upper control arm parts after painting with Steel-It in black, with Steel-It gray where the control arm would have been left unpainted from the factory.

Using Moog components. Bushings do not appear seated correctly. What say you? Thanks so much for any guidance.

definitely not seated all the way, the little bumps should be pushed all the way till they stop, same with the other ones, need to be all the way in the hole. might be able to just tighten the nuts down more, or get the press back on them to push in fully... or use a big socket & hammer.

That’s the wrong bushing.

Yep .. they are not going to push on any farther ... the inner sleeve is obviously up against the shaft step already ... they are too long.

How do the new bushings compare to the ones that came out?

Ran into the same issue would press one in and it would push the other side out. Probably the wrong answer but I shaved a little off one of the bushings to get them to seat.

Thanks for all the input. Foolishly, tossed the old bushings, so cannot measure.

These were part of a Moog kit, which also included the cross member (not sure of its technical name) the shaft of which the bushings are mounted.

As these are not expensive, I ordered a new set, so we will see. Several forum members have indicated that the installed ones appear to be too long and from an earlier model year GM application.

Will keep you all updated and thanks for all the kind assistance!

Not to be the voice of dissent, but the control arm is actually riding on the center of the bushing as they sit now... I wonder if Moog decided that is a better design than putting the control arm out over one end? I'll be curious to see how your new ones look.

One thing that happens when pressing them in is the distance collapses some but where the bushing hits the cross shaft does not so they can not press all the way. Looks like they are both seated on the cross shaft

New set of bushings is exactly the same as the ones shown, so wonder if more compression on the one’s already installed is possible - simply were not pressed in enough? Will try that and report back.

How did you press those in? You didn't press them in by just the inner sleeve did you?

For instance using a piece of pipe or something that only contacts the inner sleeve and not the outer shell? If they are pressed that way it will press the inner sleeve THROUGH the outer shell ... then the inner sleeve will be seated on the cross shaft step but the outer shell will not be seated on the control arm.

No sir! They were pressed on the outer “shell” of the bushing, though perhaps not hard enough - a friend did them for me. Will try my hand at it, of course using the correct press tool. Will report back. Thanks so much.
