Shudder while starter is cranking (not while driving)

How has everyone been? Haven't posted in a while...

2005, 4x4, man tranny, 4.0L, 190,xxx, miles, 3in proper lift, 33's.

Engine runs as good as it always has.
I removed, rebooted and reinstalled the driver side axle maybe 1000mi ago
I did not change any other parts or anything that brought this issue up (started maybe 200mi ago)
No vibrations or issues while driving
definitely not misfiring.

One day, I noticed a slight wobble/shudder while cranking the ignition.
Truck starts and runs and drives just fine.
When turning the key off, the same shudder happens as the last engine revolution happens.

It almost seems like a balancer issue, but it is only while the starter is cranking and on shutdown, so i got underneath and checked the starter.

The starter bolts are tight. Could the flywheel cause this? I did replace the clutch and TObearings etc about 10k ago and everything in there looked good.

I push started the truck by rolling downhill, just to see and I did not notice the shudder.

What else should i check??
Thanks for suggestions.

 

Possibly with 190K miles that the rubber in the engine mounts is getting a little tired... As long as it drives and runs normally with no codes (Check Engine Light) I wouldn't over think it.

 

Likely just aging components making it feel different
Worn motor mounts, etc

 

Aaaaah, motor mounts. Glad i thought of it!

Thanks, I'll check that later.

 

Thanks. my CE light is only the same charcoal cannister related code that it gets regularly.

engine mounts, I overlooked that possibility in my troubleshooting. thanks.

 

Thanks for the suggestions, I had the wife crank the starter while i observed the engine mounts. They don't look cracked, but do appear to wiggle a little more than they should.

 

Well, shortly after we noticed the mounts shaking too much, the driver side finally gave... It's only 20 years old.
