I saw this on the rusty's site when i was looking at the part to their version of the Superlift kit. I knotice this roller on the rear diff. I have never seen this before. It looks like those roller on a boar trailer that help the boat roll on. I assumed it is meant here for protection of the rear diff/driveline u-joint if you were high centered on a rock or cliff. OR some kind of counter balance weight or something.
Does anyone know what this is?
Got me dude I have no idea. Looks like a good idea though :)
It's not centered with the rear diff, tho. I would think you'd need another one for the other side.
Vibration dampener most likely. Looks like an 8.8 rear diff.
I just took a better look. Not an 8.8, but does look like a vibration dampener.
Its a vibration dampener. Reduces drive line vibe propagation throughout the rest of the vehicle.
They can be found on some tcases as well.
Cool find, how long will it be before someone puts one on their Commander?
I wouldn't put one on if you're not having issues with vibes.... otherwise its just another thing to get caught up on.
thanks! I guess i dont need to order one then! you saved me some cash!heheQuote:

This isnt an upgrade by any means or anything thats going to prevent damage to your Jeep while off roading.
