    RTAB Orientation Question

    In the process of replacing my RTABs, but I think the I might have the bushings oriented the wrong direction. Because of that, I'm having trouble to aligning the trailing arms with the carrier.

    One side/lip of each of the rear trailing arm bushings is thicker than the other.

    I believe the orientation should be: (same for left and right)
    Inner Bushing: Thick side faces in toward diff
    Outer Bushing: Thick side faces out toward wheel

    Can anyone verify this?
    Any suggestions on aligning the trailing arm with the carrier?

    Thanks

    Thick sides are outermost for each trailing arm.

    Finally found a few more pictures like those online. Surprised it really hasn't been brought up more.

    Thanks for the validation as always.

    I was looking for this - almost thought I'd put them in wrong before as I now get some rubbing - maybe just too much stress during cornering on sticky tires...

    The inner side of the bushings should have some rubber sticking out. Looks like yours are worn. Just did mine yesterday. What a pain. Looks like yours are installed correctly though. The thick end of each bushing should face away from the arm, if that makes any sense.

    I used the OEM style made by Lemforder. Almost a month now. So far no issues. For RSFB, i used the power flex bushing.

    see picture below with new bushings..



    Old RTAB's were in good shape (as far as i can tell). 14 years old and so changed it.
