2004 V70 flywheel material defect Loud Starter, Chipped & Mashed teeth on flywheel/flexplate Topic is solved

It truly is a lonely feeling when you hear this noise (AND just bought/own/service your own vehicles). I’ve been in many a pickle, and have always found my way out of the situation.

First of all, you need to decipher if your love for your XC is abundant enough to tackle this job. It is a hell of a task for just about anyone, FYI. You will need to dismantle your front suspension & driveline from the front subframe, then remove (in its entirety) the subframe. Then you will need to remove the transmission, while suspending the engine and all it’s weight from above. Once the trans is out, replacing the flywheel & rear main seal is a 10 minute job. A days work (or half day the 2nd time around) to get to that 10 minute job but hey, you’re learning! And saving money! And no, I haven’t replaced the flywheel on this particular car again. Still sounds just as healthy as the first time I started it with the new flywheel.

I think you are going to need to invest in a used flywheel (and maybe also a rear main seal - may as well as long as you’re there, so long as you can source the tool to install it…) and tackle it yourself. Surely you have a friend that is mechanically inclined. Even if you have to pay someone to hold your hand, it’ll be well worth the “tuition”. Back when I did my flywheel I was pretty green with P2 Volvo’s. You learn as you go! Everything I’ve learned over the years has been from experience, experimenting, and of course, this place! MVS!

The first thing I would do is put your feelers out for someone who has access to or owns a 2-post lift. You can do this project on the ground, if you can safely support the car at a high enough level to drop the transmission out the bottom & sneak it out from underneath. I would budget no less than 3 days time, figuring on a novice level wrencher.

I had the luxury of a transmission jack and a 2-post lift at my disposal, plus air tools etc so it wasn’t a terrible time. I still spaced it out over 2 days & the final product turned out great.

Thank you for the suggestion. Good idea. Yes it absolutely is brutal and some were mentioning they need a special tool to get flywheel off so they don't want to deal with that. Do you or does anyone know if that's the case or anything else I need out of the ordinary? I think that is my best option. Thanks for your help!!!

You will just need a good set of 12-point sockets for the flywheel - the fasteners are 12pt. I used an impact to remove the screws on mine. Threadlocker is a good idea when putting them back in

I used an assortment of other tools throughout the process, but nothing that was super special. You will absolutely need an engine bridge to suspend the motor from above.

Pretty sure it can be done with a jack under the engine with a slab of 3/4 ply to spread the load.
theres a video of a guy doing it in a driveway in 1 day.
