Default Trailing Arm Eccentric Bolts Seized

Looking for tips on how to solve this.

Ive had a few hiccups in getting my TT aligned properly and have solved all issues but one (typical new ball joints, tierods, some aftermarket adjustable rods)

The last hurtle is the rear tailing arm eccentric bolts.

so we are all on the same page, here is a link to 3sx who has the diagram. I am talking about bolt 615 in AWD rear trailing arm

https://www.3sx.com/rear-subframe-co...-3000gtstealth


I think it is a safe bet to say the bolts are seized in the bushing sleeves. Id rather not have to hack it all out and replace everything. but if I must I must I must.

but first lets try clever things to save them. besides the usual unsticking methods, the access makes it challenging, and would rather not drop the subframe.

I was thinking I might be able to rig up some kind of pusher, to push from the nut side and then add gentle heat to the bolt side. keeping the pressure and varying expansion rates it might pop?

if I had to cut, I THINK a cut off wheel in the pocket and cut the hardware. then perhaps swing the trailing arm out of the pocket then beat the bolt shaft out? or burn/cut/press the whole bushing assembly out.

anyone fought these before?

Damn good question!

Cutting the bolt and dropping the arm is the only solution I am aware of. I am interested in any brilliant solutions as nothing I tried worked.

Mine has been stuck for years and the only way I have got alignment right is with adjusting the track end on my disabled rear rack to add the required adjustment on the "pivoting" part of the trailing arm - if that makes sense. Seems to work for me as daft as it sounds but I would like to get that bolt sometime.

I'm in the same boat - been seized for years and I've been able to get it in spec tweaking other areas. Hate the thought of dropping subframe, but it's still on my list.

very little room to get tools in there, the angle doesn't help either. prob wont be able to go full ham on this until next weekend. so for what its worth I will spray them everyday.

I will get them out one way or the other. my dilemma is to order replacement bits now. they are a bit spendy for what they are. not against spending money, but I don't like wasting money, and there is that 1% chance I might be able to save them.
