A jacking question
Discussion
Sorry if this turns out to be naive.
VH V8 Vantage.
One rear wheel jacked up, the other rear wheel on the ground.
Gear selector in Neutral.
Cannot rotate the raised rear wheel.
Is that because of the limited slip differential restricting rotation?
Perhaps need both rear wheels raised to rotate, but that becomes a palaver to achieve, because of the small (safe) jacking locations.

Hello Dewi, hopefully your famously reliable car doesn’t need something fixing at last ?? 
Assuming you haven’t left the handbrake on, and don’t have binding brakes, then it’s the LSD. All VH AM are fitted with a simple viscous LSD within the transaxle housing. It ain’t the best, but humans are pretty weak (about 0.2hp) when compared to your 400+hp motor, so you might struggle to turn a rear wheel in the air by hand if another was on the ground.

Probably teaching you to suck eggs. You refer to "...gear selector in neutral...". Does that mean you have a manual, or is it a SportShift?
If it's a SportShift you know that, no matter what gear you selected before you shut off the ignition, the gearbox will engage a gear as part of its shutdown process. You need to do a "double pull" simultaneously on both paddles with the car idling, then shut off. You should get a warning in the DIM (plus a warning chime, I think) that the gearbox will remain in neutral when you do the "double pull". This will all reset itself the next time you start the car.
It's so you can push a SportShift equipped car, but it will also free up the one wheel you have jacked up to spin, otherwise, with one back wheel still on the ground, once you overcome the LSD you'll be turning the prop and trying to turn over the engine.

Thank you everyone for your helpful comments.
A manual car.
So it is as I suspected, resistance by the LSD stopping (weakling) me turning the off-ground wheel.

Thanks, everything is fine. Just a general look around, prior to 2023 driving beginning next month. The winter hibernation is nearly over. Might even reach 20,000 miles on the clock this year! Forums | Aston Martin | Top of Page | What's New | My Stuff
