New thoughts: The saw tooth edge on the bushings may be to lock the bushing from rotation after the long bolt (10) is tightened. There are short screws with washers (items 2 and 3) shown in the diagram that appear to intersect with the long bolt from the bottom. Are these screws to lock the long bo...

Are both sides just as frozen? That is my best guess. And yes, both sides are equally frozen. THAT change in bolt...

@BlackBart this all checks out with my sources as well; yep, it's a big bolt and we're looking at the head end (apologies if I swapped terms along the line). I've already tried pounding on it with a 4lb mallet, and driving it with a c-type bushing press (both from the nut end, so would be driving it...

Maybe more heat will break it loose. volvolugnut @volvolugnut I hear you, re: frozen bushing inners - I've considered this as well. If the shaf...

Greetings all! This board looks pretty sleepy today but I remember when it used to be hopping; maybe a good Volvo mystery will draw a little attention... I'm doing a full suspension/unsprung overhaul (bearings, bushings, ball joints, shocks, springs, brakes) and have run into what seems to be a majo...
