Haven't been on here in a while but careful running those. Had a set myself and they bent on me. RE wouldnt do anything about them with me even working at 4wp. They redid them shortly after I bent mine into a S just by going into a parking lot.
If I shim it out it would hit more. It's hitting the tip of the starter that goes inside the bell housing. The only thing I can come up with is grinding down the face of the starter to make it go farther in so it won't hit.
Ok so I've been having this issue for a while and thought it was a broken flex plate. Put a new one in and it's still doing it. So I put in another transmission thinking it was something to do with that and it is still doing it. While idling you can hear it ticking as it hits the flex plate...
Well I have the RK steering and have had it for years. I love it and have no DW issues at all, no bump steer, nothing. Its nice and tight and drives great with it. I would check the knuckle and see if there is play inside the hole that had to be drilled out bigger. Maybe its gotten worn bigger.
