Here's a bone. Search for "Curt 31055" Also good for a spare carrier

Thank goodness if we *did* have to pull a boat out of a lake in reverse we have a 2.7-to-1 Low range. Most of us, that is.

Your old rear diff begs to differ.
Quick summary: Using the recovery strap alone on the stuck van was ineffective, but moved him a little bit. I wanted to be in a position that I could be driving forward in case I wanted to use the engine to assist the winch, so I put the winch in the rear receiver and strapped my front shackles to a nearby tree. The van was too close, and I didn't get down to the final layer on the spool so the winch could develop its rated force. So the winch stalled out without extracting the van. At that point, using the winch line as a taut strap, I just started pulling in 4LO and the diff broke at just over half throttle. But the van started moving. :woohoo:
The root cause was the G80 housing (holding the spider gears) cracked near the ring gear, and I'm pretty sure the bent axle tubes allowed axle shaft stress to transfer to the cast iron housing.
I've used far more than half throttle in 4LO before, climbing rocks, and this wasn't a case of wheel spin locking up the G80 and shattering it with the engagement stress. There are tangs in the stack of clutch plates designed to shear in case of this kind of shock, to prevent total destruction like I had.
Guess that wasn't such a short summary after all. Carry on.

Only my proctologist knows for sure.
Oh ok. I thought you were using the winch mounted at the front.Quick summary: Using the recovery strap alone on the stuck van was ineffective, but moved him a little bit.
