    Is this cam bolt installed upside down?

    I noticed it looked a bit off to me but didn't think anything until I saw an ad for the Marlin crawler gusset tabs that specifically mention they prevent sloppy alignment techs from installing the eccentric cams wrong.

    I'm guessing it is as it hangs underneath the vehicle and assume the notches should be on the same side as that little arrow.

    If so, aside from it hanging and being at risk of trial damage? I'll need to take it back to the alignment shop tomorrow and would like to know what to say to them.

    It doesn’t look right to me, but it’s also not a great photo.
    Are the tabs on both sides of the flat washer part of the cam flattened out and damaged?
    Have an alignment print-out from the shop?

    Yup they are upside down, typically from a tech not familiar with them.

    It's probably fine, there's lots like that, but it definitely makes you lose a bit of confidence with the alignment.

    Do you have the print out? Usually I have the rear eccentrics maxed to the side on lifted trucks.

    The little ridges are there and not flattened, it may just be upside down?

    Would maxed out be with the tab aligned as so?

    Do you have adjustable upper arms? The alignment looks ok, the caster is actually a touch high, but if its not rubbing and driving fine, its probably ok to leave.

    I have JBA UCA which aren't adjustable, and specify 4.5 of positive caster

    Nothing seems to be rubbing and it seems to drive fine although I'm a bit worried about a few things.

    - the cam getting caught up on a rock, which Marlin crawler mentions in the advertising of their reinforcement gusseta.

    - I've also read it can potentially enlogate and damage the holes?

    Seeing that you have steel skids AND LCA skids, I’d recommend that if you are off-roading to use those, you may want to reinforce the cam tabs… Total Chaos or Marlin.

    Edit, you beat me to it with the link.

    At glance it looks like the RCI LCa skid may require a bit of cutting to work with the skid portion of the MC kit, I'll also have to glance at the RCI engine skid tomorrow.

    So from what I'm gathering, they're definitely upside down which doesn't pose a huge problem for day to day driving but as they're exposed, could potentially get caught when skidding over something off-road and effect the alignment oreven damaging the hardware and mounting location.

    Can that one cam likely be adjusted by itself or will it likely requiron
    Looks like the 3 of the 4 cam eccentrics they touched are all improperly set?
