I have just installed a KAAZ diff on my be3 box. I cheacked that the diff did not foul on the gearbox casing, and I checked the bearings were in the same position as the diff I removed.

Is it normal to feel a lot of resistance when turning one ( or both drive shaft) or is some thing not right inside the diff/casing.

If I turn one wheel with both wheels off the ground, then the drag is quit considerable.

Think thats just how they are ? can't really see how you fecked it up if you put it all together correctly ? I assume you have the correct diff oil in ?

I just put my BE3 box back in this afternoon after having it rebuilt in to a new case. Once i had the shafts in the hubs, i just went to spin it a little before going any further, and i couldnt turn it without a wheel on the hub.

Although that was before i put the oil in, so that may have added slightly. But aslong as it is all fitted properly, i wouldnt worry, its not like you are just spinning one side of an open diff.

Are you 100% that you ground enough material out of the casing? With both wheels off the floor and the car out of gear the wheels should spin fairly easily.

I assume you've fitted the original crownwheel onto the diff rather than a different one?

There arent any clearance issues with the Kaaz. Well, there werent on mine, unless the diff housing vary in any way.

Good to know, as I found no clearance issues either.

With both front wheels in the air, and the car out of gear, is there a fair amount of rolling resistance on one wheel?

Yes with just one wheel in the air you won't be able to turn the wheel very easily.
Have you driven it yet?

Bit OT but did I spy you at pugfest today ash? I was in the White 309 track car.

With only 1 wheel in the air, I would expect the wheel to be difficult to turn, but should it also be difficult to turn one wheel with both wheels in the air.

haven't driven it yet though.

I'd have thought so, an LSD is designed to stop or limit the wheels turning at different speeds, so using a bit of logic trying to turn a wheel by hand would result in you effectively having to turn both wheels ie twice as hard as the standard diff. Ish. Turning one driveshaft by hand would be like the car trying to spin up a wheel with low or no grip, which the diff is designed to limit, so you're fighting the diff there.

My money's on yes, it's supposed to be like that.

Unless i'm talking absolute bo***cks. But it makes sense to me Laugh

The drag was there with only one drive shaft fitted.

Drove the car, and the diff has freed up a lot. Will be trying it in anger on Friday.
