Swapping my new 8.8 rear in

Andrews24 · Mar 27, 2021

Pulled the old 8.8 4lug drum out, my new 94 5lug disc 8.8 is plumbed and ready to go in... question tho, I forget the name of the thing on top/bottom of the diff - I believe it’s for vibration... what is the general consensus - people not running it? I seem to recall some saying it isn’t necessary, but then again I do dream things...

EDIT... is it called like a Dog Bone or something?

I left the Dogbone on my car but don't think its that big deal one way or the other unless you are trying to eliminate weight for racing.

I just redid my rear end with new gears and a five lug upgrade. My plan was to leave it off unless someone here convinced me otherwise. Then it’s one more thing I need to clean, sand, and paint.
I still have a while to contemplate before I put the rear back in the car, so I’ll be keeping an eye on the replies as well.

Dog bone, moose balls, vibration dampener, pick a name that you like.

Yup. Vibration dampener for the driveshaft. I took mine off, but will likely put it back on

Mines off since disc brake upgrade( over a year,8,000 miles) no problemo .

Ford would not have spent the money and added the weight of a weight without a reason. If your driveshaft is precision balanced and U joints are in great shape, it probably will not be missed.

slow84lx · Mar 28, 2021

Agreed. Ford put in a lot of engineering time, $$$$$, and the cost of adding the part in production. However, most of us are no longer using the stock driveline for which it was designed. Once you start making changes it may or may not be a relevant piece of equipment with that combination.

I guess once you change your gears, assuming your u joints and driveshaft are in good shape and balanced, it’s just trial and error as to whether you need it or not?
