Rear right suspension(?) bushing identification

[DerekA]

Afternoon all,

got a problem trying to identify a part that the tyre shop reckon needs replacing as the existing bushing is crumbling.

Went to Volvo dealer who said they could get me a replacement part but they wouldn't tell me what it is called or the part number. Excellent!!

So attached is a photo of the rear right axle from underneath. there is a bolt that runs through both connections (circled red and green). the bushing in the green circle is what the tyre shop said is crumbling and needs replacing.

Can anyone identify what it is called and even cooler could tell me what part number it is and/or even if it is a DIY job.

I have studied Volvo drawings but cannot get my head around what it is. Volvo is trying to sell me the entire kit (nut, bolt, both bushings) which may well be the best thing to do. But they also say I should replace the other side (entire kit) as well. So instead of one bushing, they're trying to upsell me two complete kits.

I hope someone can help here.

Cheers
