I needed a truck, as my dodge is down, and I don’t want to drive my Jetta on gravel roads.
It has over 570k kilometres on it.
It has pretty bad blow by, but starts good when plugged in.

The rear diff is, well, I’m not sure, last time I drained it there was pieces of roller bearing from the spider gears rolling around in the bottom.
Been there Done that. My 1993 was pushed past retirement because of some Dodge problems. Nice to be able to toss a NV5600 in the back of a pickup...
Oh, That's why they call em a cumapart...
PO left me the above mess. I have to have it put back together and then I will find a trailer to pull "The Rim" and make sure they get seated. Of course with Total Seal Gapless rings...

Vanity ain't my thing. Paint don't make it go faster after all. However having a solid vehicle under you is important. The metal "reading part numbers in the oil" from the rear end is reason alone to PARK IT! RAM had some recalls over rear ends locking up and the trucks going into the concrete barrier at freeway speed. Engine Failure I don't consider as critical as tire falls off/ rear end locks up. (Unless the engine failure say knocks the brake master cylinder off... or it's on fire while stopping.)
Even back road speed: any new chunks coming off or bounced out of the bottom of the differential can instantly lock up the rear end. Things like to roll over in a turn on rear end lockup where the damaged spider gears are turning the fastest. After all a proper correction will have you going sideways...
You have looked at the clues, frankly Warnings, GM vehicles are known to give operators before failure. In the interest of Safety First esp. innocent bystanders: park it until the serious problem are corrected.
After the above IMO it's earned the $500 putting four road rats down. It don't owe you anything and again for Safety IMO and it's long list of wore out plus rust (at ~350K miles) I would park it and scrap it.
Your time and money is better spent getting your Dodge back on the road ASAP!
