i've been having trouble with caster in the front on the driver side
can i use the radius rod to adjust it ?

 

Isn't caster determined by the radius rods from the factory?

 

loosen steering gear cradle and radiator lower support. Get two big pry bars, pry them in negitive or positive caster. You can get up to 0.5 degree +/- caster and some camber adjustment as well. I did this with my 89 4 door DX.

 

what kind of problem are you having? theres really no adjustment on ef's for caster. pulling the front crossmember forward will increase caster pushing it back will decrease caster. The passenger side should be 0.5 degree in front of the other.

 

The factory manual says that you cannot adjust caster on our cars. That's because they did not provide a way to adjust it. You can adjust caster a couple of different ways. First, you can shim the radius rod with some washers, or you can use eccentric bushings in the uca, and install them "unevenly", or not in the same position as each other, to affect caster. good luck

 

did you get your alignment taken care of?
