I am putting my 4" IRO lift kit on and am having issues with the bolt in the leaf springs on the unibody side.anyone have any tips on how to get this bolt out..any advice is greatly appreciated

 

Spray the bolts for a week with PB blaster or kroil oil, use an impact wrench or a 3' breaker bar. If it seizes up after several turns, cut the bolt out.

 

Front bolt on the leaf spring?
Isn't that the one that has red thread locker on it from the factory?
I think heat is the ticket for that one.

 

Yeah that's the only thing I havent tried yet is heat I have a 1/2 snap on impact and it's not budging that bolt what so ever...so maybe I'll try some heat for a bit and see what happens...I dont want to cut the bolt,because it's the side where the nut is welded to the frame,how would I get the bolt out if I did have to cut it

 

You are correct.


That's what's required. It is intended to be that way. PB Blaster is not going to help.

 

Get that bad boy hot. No other way

 

Thanks the torch worked it came out...thank you guys for all you're help

 

hi,
did you heat at the outer end and let the heat travel through the bolt or did you heat at the nut end and burn the bushing.
Thanks,
I'm doing the same job right now.

 

Thanks for asking cause I have always been kind of curious about that too.

 

Heated the bolt head for the most part but did try to heat up the end where the nut is welded to frame

 

My hopes is to one day duplicate the Up Country suspension.
Was thinking maybe just cut the spring off. I see no use in keeping them.
Figure I do that I expose the bolt and could just heat it up closer to the welded nut.
Not even sure if any of that is even feasible.
But if heating the head of the bolt gets the job done why bother? LOL.

 

The heat should be applied to where the LocTite is: The end of the bolt that screws into the nut. In other words, torch the nut.

 

That is what I kind of figured.
But how exactly do you get at it?
Have to actually look at it one day. LOL.

 

ok, thanks.

I normally heat the nut to expand it. But you can’t get to it in that pocket without torching that bushing.

but if we are mainly melting locktite heating the outer end should work

 

Ralph, cutting the spring probably won’t help much. I think you would have to get the spring loop out, then the rubber bushing before you could get heat to the nut.
Probably do able but a lot of work.
unless you are willing to heat the rubber up. Personally, I don’t want to fill the shop with black smoke, or breath it.

the only other way I see to heat the nut is to cut a access hole in the bottom of the pocket that holds the nut. Then weld it back up.
Cutting that access hole is a way to get a wrench in there if the spot welds break and the nut spins.

Im going to heat the outer end. And see if melting the locktite is enough.

I took one side apart yesterday. I got it loose, but it was a workout. I’m to old for that stuff.
