No, I don't have it apart yet. Weather is not good to make a replacement.
Also I'd like to be sure that I can put new bearing after removing old. That's why I asked here..
But seeing current bearing will be the best to be sure, really
May be I'll do swap somewhere at spring or even summer

Just got pictures from dealer.
Chris, you are worng, pre-86 also has 1 wide bearing.

Cool Glad you've got a definite answer mate! In which case, make sure you get the oil seals to change too.

It looks like mine must be the big single bearing as you've seen that Scantech one now too, so hopefully I won't have too much trouble when I come to do it.

I wouldn't say that answer is definite..
Pre and post 86 cars have similar construction with one bearing, but which one is used can be decided only after removing old.
Post-86 doesn't have oil seals, bearing itself has that seals.
The only chance to get type without disassembling-remove break drum and see at center. According to pics, they are different, but not sure about real life.
I'll post pictures later

i also have been struggling to get hold of a rear wheel bearing for my 1.4 340 mk2 on a c 1984 does anyone have a bearing code so i can get one made up at out local bearing company as i don't want to go stripping it down and end up have to wait days for one to get to me i need the car every day of the week for work

I think this one:

340 B14 1976~82
340 -CH.120999 1983~85

volvo:
3105765
scantech: 52.115

I now have the same issue - need the replacement part before I take the car apart.

Need a bearing for an '84 360 2.0 - anyone have a Volvo part number for this?

I have a spare Volvo bearing (double for 360) that I never used because I could not find anyone with a press to change it. In the end I just used a hub from a scrappy. Its hard enough to get the hub out, you need a huge socket and the right puller.

I have had no problems and every car i have had i have done rear wheel bearing on and every one has been the single wide bearing, without an oil seal....
QH do a good kit so do firstline.
