Normally having the hubs locked will not cause performance problems, only additional wear and tear on the front driveline and poorer mileage. That is with an open front diff.
With a locked front diff both front wheels turn at the same speed all the time, even when turning.
Ergo, when turning...
I agree 100%.
There is a saying. Lockers just get you 100 feet further into the hole before you get stuck.
With a winch you can just pull yourself that extra 100 feet.
Lockers will definitely give you an advantage. Especially in rock crawling where you often have very little weight on one...
This might be relevant.
I have a 5.3l with the 4l60e in a Chevy Express van and I have pulled my 45 with not a lot of effort, as well as an enclosed trailer that was about 5000#.
My mileage was about 75% when towing.
Here is a pic of what you had... and then the extractor broke flush with the block. Same situation as most of us here I expect.
The large flutes on the extractor make good spots to tap with a thin punch. A finish nail punch works good or a flat punch with a good sharp corner.
If you tap it...
If your trans tunnel cover is off, you can stick a 4x4 across the cab resting on the door window sills. Use a heavy duty ratchet strap to suspend the tranny. Rachet up the tranny to approximately the right height and walk the 4x4 forward until the input shaft is inside the clutch assembly. Then...
So I dug into it a little tonight.
The inner PS u-bolt broke off at the plate, perhaps due to the force from the curling plate (see pic 1). It's from the beating that a truck with 29" tires goes through on the Rubicon I'm sure.
Once the u-bolt broke the spring and the axle started moving a...
I have a similar clunking sound on mine when backing up with the wheels cut hard.
I noticed that I had a broken u-bolt on the DS.
It was very hard to notice if you weren't looking for it.
Waiting for new u-bolts now to see if it solves the noise.
I think the cross member that holds the hoist is bolted to the frame. Check that out. I'm speaking from 40 experience here.
You may also be able to spray PB Blaster or something like it up through the spare.
