Mustang ll caster adjustment

Is there any tricks to adjusting caster on an aftermarket mustang ll? Mine has strut rods which are not adjustable. I will mess around with it but it doesn’t look like there is much forward to back movement of the upper control arm in the adjustment slots. Thanks

Are you having problems? Or are you just setting it up for the first time?

Thanks I will start at those specs, just having trouble with the adjustment procedure for the caster. I was going to go for 1 degree + since I have a manual rack.

Pic might help as there are different styles...w/ stock ones using a cross shaft and cross-wise mounting slots, the fastening for the upper a-arm shaft has a forward slot ahead of the axle c/l and a rearward one the same distance behind, there is really no forward-back adjustment per se, for caster you have to bring the front of the upper a-arm out and the rear in, or vice-versa. If you've set the camber first, just make sure you keep that "setting" by moving front and rear the same amount in the opposite directions when you're looking for caster. I don't know how they recommend moving things but I get best results by having the bolts snug, not tight, then using a brass or soft hammer to tap on the shaft or a-arm or whatever for movement. Placing a piece of masking tape on the frame up against the shaft so that you can see a gap created when the shaft is moved is one way to monitor movement. Then when you think you've got it you crank it all down tight.

Ideally this all results in the upper a-arm shaft winding up parallel to the frame rails more-or-less, if the caster you're looking for is the same as what the frame was designed for (I agree about the 4 degrees) but it's not that important, they can be skewed a bit without hurting anything.

Thank you guys, after looking at it and wiggling stuff I realized the way the caster adjustment works like you mentioned. Thanks

You have the sliding arm type. There is a tool for making the adjustment easy. I've used them on Fords and Mopars. Here's one for $20, grab it up!

Ok thanks for the replies...one more question. I have measured the caster angle very carefully and came up with about 1.6 degrees with the wheel tilted “out” at the top. I understand this means positive camber but is that also positive caster? I turned tire 20 degrees, zeroed out the gauge and then turned 40 degrees back and measured it at 1.6 degrees. I was shooting for this as long as it means positive caster. Thanks
