200 Nm + 180°, had to call on my old pal Archimedes.

 

Suddenly I'm a Matco fan too. I needed triple square sockets because Germans can't use regular fasteners to attach a wheel bearing/hub. indecision

Matco had a decent price on their impact triple square set, bought a 12 pt 24mm socket from them for the axle bolt too, and got my order in 3 days. I'm not going to be replacing my entire arsenal with Matco anytime soon, but will probably be adding more of their stuff as needed.

I've always had to do those with the wheel on... and the car low enough that the tire touches the ground.... and the engine running so the assistant applying the brake could keep the tire from spinning.

Other side was still on the ground.  The DSG's parking pawl may not have cared for it, but the only popping sounds were from my back.

One of these things is not like the other, one of these things just doesn't belong.

Where is the rust on the flange?  The chisel marks?  The deformed metal from beating it to within an inch of its life with a blacksmiths hammer?  None of this seems right.

When I moved to New Mexico after wrenching on stuff in the rust belt for four decades I was shocked to learn that those are not a tight press fit!

I did 3 winters in Ohio, I served my time, I'm a reformed man, no chance recidivism here.

Thankfully I was dailying an 850 at the time, their bodies are galvanized, but none of their fasteners or hard parts are.

Can someone give me the "for dummies" explanation on chain driven rear axles?


 

I think it's cool af but I don't understand the reasoning behind this vs. a driveline and regular live axle.

In reply to barefootskater (Shaun) :

You don't have to be able to hob gears or cut splines to make a chain drive.  Gears aren't hugely complicated to design, but the machines to make them are.

In reply to travellering :

I would think that a chain drive also means you don't have to figure out how to support the wheels while also sending power through a concentric shaft.  That is a non trivial thing to do.  A chain drive you would be able to use the same kind of bearings/spindle as on the front, no need to have a hollow spindle to run axles through, and then try to seal the whole mess.

 

Semi floating axles, like flathead or pushrod engines, is an engineering exercise in simplifying for mass production, not making better.

In reply to travellering :

That makes sense, though I'd argue that they are obviously making the gears already as the drive sprocket is perpendicular to the engine rotation. Engine>trans> 90* turn somewhere. 

I was thinking it might be to do with being easier to work around suspension articulation with a chain than with a driveline and slip yoke and u-joints. 
 

Not trying to say you're wrong! I just habitually question mechanical stuff. Almost like "well I didn't design it so it must be inferior and not work well."

The U-joint was still a fragile new technology when The Beast of Turin in your photo was built. Not trusted for such a high torque application. Chains had been driving machinery for over a century and were trusted and predictable.

Ok, it's quite a picture now.  But the back round is cluttered.
