If you have a bent turbo wheel (3546745).... 850

... and you have 3546745 stamped on it, it also goes by H70185, or 9134402 (volvoworld has a pic by this number, dealer goes by this number as well).

I just had a bent rim replaced (bent AND cracked, so they couldn't fix it), and had a difficult time trying to track it down to the exact model. It's a 5-spoke, 5-lug swept design, and I believe it's called Columba. There are a couple that look very similar (one of them is Perfo, which I like better). Thought it might be of help to someone going through the same thing.

At a local dealer, a new one would've been ~$380. An on-line purchase for a reconditioned one would've been anywhere from $230-$280. Got a reconditioned one locally (Newton, MA) for $200 (+tax). If anyone wants to know, I'll give out the name of the shop. Not affiliated, and first time client, but they seem to know what they're doing. Will see how it goes and repost if anything wrong happens.

Getting it fixed would've been $100 + $15 (mounting & balancing). Hitting the pothole happened a couple of weeks just after swapping out of winter tires... ARG!

Funny thing is, 70 series uses same H70185, but they've got left AND right, and universal (only right) for 850s. I wonder if the 70 series brakes are different in terms of cooling?

    i believe the perfo's were on the s70 which are similar to the colomba's. The swirl is the other direction. I myself had two damaged colombas from the dreaded potholes. i did my research and ended up buying from ebay. i ended up getting a set of 5. so I have now 3 good ones left over. I figure there are more potholes to come so I'm prepared. the roads are crap here and its like an obstical course. And those wheels damage easily.

      So, what is it about 850 wheels? 850

      I would've gone the ebay route, but I rely on the winter steel wheels for potholes. The pothole accident happened just after I got the winters off, and had to find one quick with school vacation just around the corner (planning on a road trip).

      I do see a set of four on ebay right now, ~$400 with 3 days left.

      What is it with 850 wheels getting damaged so easily? I lived in the same area close to 20 years, and this is the first car (for 1.5 yrs only) with TWO pothole damages, one on alloy, one on steel. Other cars I've owned never had such issues, steel or alloy wheels, and yes, I have gone over potholes in other cars as well. I don't think my (or my wife's) driving has changed much at all. If anything, I've become much more careful.

      Is it the tight suspension/springs on this car that makes it less forgiving? Even the shop owner said they see a lot of 850s come in with bent wheels.

    My 98 S70 T5s turbo wheels are all the same (no left or right).
    Maybe left and right versions are newer then 98?
