Do you have a picture of where the motor mount caused a crack in the tube? I'm curious which tube and where exactly.

Oh you can most definitely run it without the driveshaft. It's FWD full-time, and engages the rear wheels when slip is detected. The shafts are always rotating and the Haldex system simply engages input from the engine as needed.

For what it's worth, mine is also not perfectly straight in exactly the way you describe. I replaced mine a few months ago and both the old one (which was certainly original) and the new one looked like that, so I'd say it's designed that way. As for the vibration, you can disconnect (or remove) the...

I've heard the seats in the XC90 are fairly interchangeable between years. I'm wondering if maybe someone procured some seats from a wrecked 2014 or something and transplanted them into what you drove (wouldn't that be nice).

Can you have a helper verify that the crank is moving while you're cranking? They should be able to see the power steering pump and such spinning while you crank if the serpentine belt is hooked up. It almost sounds like the starter isn't engaging the flywheel or sort of the sound I'd expect if the ...

Oh, also, do you know what caused the low oil pressure? Even if you got by with no damage to the engine, low oil pressure's a BFD and isn't sustainable. I've heard one common cause is the seals between the oil pan and the block leaking due to age/cracking or being installed incorrectly (folded, twea...

Changing the oil should give you an idea if things are toast as well too, right? Finding lots of glitter and/or chunks coming out with the oil or in the oil filter will be a dead giveaway and will save you from having to drop the pan. Maybe run a telescoping magnet tool through the drain hole once i...

As long as it's not making noise, that grease on your driveshaft doesn't look like a showstopper. You'll want to look into replacing the CV joint as some point, though. How does the front one look? Colorado Drive Shaft will sell you a kit to replace the joint for around $100 each, but if the middle ...

Mine developed a leak after disconnecting it from the torque mount and pushing it back out of the way. I pulled it out and found the last person that worked on it had put on a black o-ring and sealed the top with RTV that had ripped. I jumped online thinking a new seal would do the trick and ordered...

This is a bit of a shot in the dark, but hard starts followed by a stumble and then running smoothly could be a leaking injector as well. If putting the key in position II for a second or two before starting helps then that further hints that this could be the issue. I would hook up a fuel gauge to ...
