Control Arms

The wrench, and socket size, is 3/4 inch for the UCA nuts and bolts.
Kinda odd that you don't have those tools, in your tool box. :dontknow:

lol I had used a adjustable wrench at the time I was trying to figure out the size...my tool set was in my wife's car.I had got 13/16"...I guess I shouldn't have trusted it! I checked it today with my actual set and it was 3/4"...felt pretty stupid:violent1:
