Gripper Diff

[boldy205 75]

Hi, i have just fitted a 2011 spec (plates on both sides of the diff) to my BE3 box, and upon trying to turn the road wheels when on axle stands there is a lot of resistance, (55Lb/Ft aprox when tested on a torque wrench)

 

The car is not in gear, i have tried slackening off the 3, 13mm speedo housing bolts which i presume is the only thing that preloads the diff bearings, its not the brakes tying, nor the intermediate bearing.

 

So unless its just a case of having to bed the diff in, im at a bit of a loss. I can see some thing burning out driving it as it is!

 

Thanks for looking

Sounds to me like the gearbox casing needs relieving somewhere.

I have been an idiot, its seems the diff is touching the casing somewhere, as i slackened off the 8 diff cover bolts and 3 speedo drive bolts, and the wheels turn a LOT easier! Hope it hasent deformed the diff housing.

 

 

Does anyone know where these usually rub?

 

Thanks

You should easily see the witness marks on the casing I would have thought

Just needs a little bit grinding out of the diff housing, had to do this on mine too.

taken the diff out, again, looks quite thin where its rubbing though, maybe 4mm, and i guess i need to take out a good mm.

 

Thanks for the relpies
