Anybody know what this thing is?

[dlascoskie]

There is some sort of weight attached to the bottom of my rear diff (and i'm sure it's on your rear diff too). I've been staring at it for the last 4 years, and i'm assuming it has something to do with controlling wheel hop or dampening the forces from the driveline, but I'm not 100% sure. Any thoughts? And any idea what would happen if I remove it? It seems like I could shave 20lbs off by getting rid of it.

Is it a rectangle block?

That would be the "dog bone". It reduces vibrations in the driveline. Some say take it off, some say leave it on. I say I don't want any vibrations.

people call it the "dog bone" i forget exactly what it does but when you change your rear gears it becomes useless dead wieght

Its to help with vibration in the driveline. They say if you go with a steeper gear you can remove it without any vibration issues.

sweet! thanks. I have 4:10's so it's a gonner!!!

Let us know if you get any vibration.

its like 8lbs...wheres Tom didn't he take his off and weigh it?

yeah it came to 10 pounds, not uncluding the steel bracket

Did you get shorter bolts and put the steel bracket back in?

i didn't reuse it, but the bracket is there for the pinion snubber, the thingy that stops the axle from hitting the floorboard/chassis

vibration damper....)(offically mot bar)

with 4.10 and aluminum driveshaft...mine has been gone the day I had my gears installed.

 

[ocbaud]

i still need to take mine off just havent gotten to it yet

so you didn't reinstall your snubber? I was wondering if it could be bolted back in after the weight was removed. I'm gonna play with mine when i drop the gas tank and install the fuel pump.

I guess I need some gears so I can take that thing off, it is so ugly it just makes it look heavy!

 

[98bluevert]

could someone take a pic of the mot bar(dog bone). Just woundering what it is so i can take it off. Don't want to take off the wrong thing.

It is not usless dead weight as some suggest.
It is tuned to the drive shaft critical frequency and not the gear ratio installed.
If you install shorter gears that means that you will reach that critical frequency at a lower road speed.
By all means remove it if you want to but keep everything on hand just incase you have issues like I did.
my car just about shook it's self apart at 80mph.
