Been really struggling with the rear suspension of the wife's Volvo. Both rear coil springs had broken. which entails removing virtually all the interior trim, to get to the top mountings and the trailing arm control links needed replacing.
One side went ok but the nearside is being a real pig of a job.
The pivot bolt has seized solid in the metalastic bush. Gentle then progressively less gentle persuasion (large club hammer and skinned knuckles) has failed to move it. Soaking in WD40 overnight did sod all. Heat did nothing but produce noxious choking smoke as the rubber caught fire,
Spent all day drilling a line of overlapping holes along the bush and it still will not move.
As a last resort I am in the process of drilling a 10mm hole through the pivot bolt, as near to the head as I can, the idea being to break off the head. The other end I can get an angle grinder to. Damn this thing is hard to drill.
This folks is what can happen if you dry assemble components. A little grease at the factory would have made this job so much easier.
Rant over.

sharp cold chisel and cut down to the bolt with a club hammer through the rubber oalong the line you have drilled ?
once you cut through the bush you should be able to hammer it with the chisel to peel it off the bolt ?

Can you not cut down through the shaft of the bolt, either side of the trailing arm?

Tried the cold chisel. Didn't work. The centre sleeve is very thick and just wont spread. Even tried using my big SDS drill with a chisel and just ended up with a headache. It's as if the bush centre and the bolt are one thing I can't get the angle grinder or hacksaw in to cut through. Really need something like a body saw. Perhaps would be a good excuse to get one seeing as SWMBO wants her car back.  |

Just looked at the parts bill from the Volvo dealer and realised I've paid £3.54 for one M12 nyloc nut  |

 Hooray, done it. Because the bolt hole in the chassis is actually a slot to allow for the eccentric, I managed to free the pivot bolt by driving a hardened steel wedge along the bush from the nut end. Think the neighbours will be pleased that the noise has stopped. Car is back together with new control link arms and springs both sides and ready for the MOT. Have to have a word with the wife about how much shopping she must be putting into the back to break the springs.

Should have given me a shout mate, I have all manner of nut and bolt busting equipment! I also have a reciprocating saw. Every bush or linkage on the ol mans jag has been like this!

I did think of giving you a shout, but I figured I'd taken up enough of you time recently and I hate borrowing tools.
This is the first time that a single bolt has taken a full day to remove.
