disks are self cleaning (or at least nearly so). that alone is why my MJ has rear disks. I'm never pulling everything apart to clean mud out of my drums again.
if it's the starter not fully engaging, then each time it happens it makes the flexplate/flywheel teeth a little worse. sounds like you found your weekend project.
are you saying the noise was happening, then you replaced the starter, but the noise persists?
I guess the worst worst case is you have some stripped teeth on the big flywheel gear.
I've heard so many people say that the dual swap was indeed mind blowing that I'm inclined to think that more tweaking can be done? dunno. I only did the swap once and had to sell that truck before ever getting to drive it.
love the bed tent! back in the day I really wanted one of those. then I filled the bed with a rollbar and supplies and had to settle for ground versions. lol
I'm guessing I don't have access to your google account? I do see the images in that last post.
most people have no idea what an MJ is, and those that do, probably haven't seen one with an engine swap. MJs are a curiosity for sure.
