mine looked like that...and I was told it was 5 degrees off and 10 is the max.
so I had everything replaced
chain rials etc.
just to be on the safe side
well when they opened up the chain they found other problems
one of my guide rails was chipped (end broken off)
and the master link was put on backwards.
I am so glad I had it done!! made a major difference in starting the car, the pick up, and the smooth ride now.
to replace everything it cost me 975.00 but well worth it
