I just noticed that I can see my flex plate through 2 holes about 1.5" diameter. It doesn't seem right to be exposed to the elements like that. Perhaps freeze plugs that were never replaced? This truck has gone 1000s of miles like this, no mud luckily but a little water has probably made its way in at some point I imagine.

Do I need to seal these asap? If so, How? Do I need to perform any other service or lubrication?


Truck drives like a dream. Just noticed these holes as I was greasing up the joints...
