Any suggestions for a rust welded shackle bolt to spring collar. Because of the bushing, whacking with a BFH from every direction has not helped and standing on the shackle and rotating the spring is only stressing the same bushing. I have also tried PB and it seems to go down but to no result. Every see this? Any tricks?

Have you tried heating it?

Heat it up or freeze it

cut it and use a punch to drive the rest out, if you have to you can use a press to drive it out but you have to take it all of the way off of the truck.

I have the spring off the truck, just cant get the shackle shaft to come off the collar in the eye of the spring. How do you heat this when that collar is surrounded by a rubber bushing? Can this bushing be pressed out of the spring to replace if I cant get the rust to break?

Yes and yes. I had the same problem and nothing worked for me. The oem bushing from Nissan is like 20-30 clams and I got my shop to press the old one out, which cost a little more than 30 lol

I'm sure it would have come out with a punch and a big drill bit but it's my dd and I didn't have time to put more work into it at that time.

You should be able to press it out with a large C-clamp and a piece of tubing or large socket. Or drill out all the rubber material with a thin, long bit.

thanks guys for the advice, got a replacement bushing and took it to a shop where they trying heating cooling and impact hammering to no result. It seems that this was better than a real weld! They punched out the part and replaced it with the new one. What a PITA
