Hi, the nut on the other side of this bolt, is it welded to the frame? The bolt is stuck, but i cant find any socket that fits the nut.

It looks like it's a torx head bolt. Torx looks like a splined allen wrench, or "star".

Yeah that's a t55 torx I believe. I broke both of my high dollar torx on that one bolt.. good luck

If you have anyway to put some heat to it I would suggest that before trying to back it out if not use a bunch of liquid wrench or pb blaster and soak it really good for a few days good luck

Don't waste your time with propane. Use MAP gas or oxy-act. You'll probably set the bushing on fire plus all the WD40 or whatever you used.

I know its torx, thats ok, but its the nut on the backside i asked about ;-) I have tried it all, but i can only get the bolt out 4-5 mm and then its stops, i can enter a nut on the bolt and turn it all theway in to the other nut on the backside, so the visible thread on the bolt is ok. I use a 50cm long wrench/pliers on the bolts head but its not possible to get the bolt out, so i will let it stay in there. Bolt vs me 1-0 :-(

I've had experience with leaf spring and control arm bushings and I believe the steel sleeve inside the bushing is rust-welded to the bolt. When you turn out the bolt, it becomes tight against the outer half of the bracket and stops turning.

In one instance, we had to use a sawzall and cut the bolt on both sides of the bushing, drop the spring out (leaf spring in this case), drill the inner half of the bolt, and use a long easyout to remove the rest of the bolt. In this case, the nut was welded to the bracket. IDK if yours is welded or not.

I hope this helps. I didn't realize you were asking about the nut in your first post. Sorry about the misdirect.
