Lowering springs install help

[KelvinllMelvin]

Trying to install eibach lowering springs at home and having rlly difficult time trying to loosen the nut that secures the shock absorber. Tried to hold from the bolt side and loosen the nut with impact wrench and no use. I tried to soak it up with wd-40 but honestly wasn’t rlly the one to penetrate threads. Am I doing something wrong or are these rlly just a pain to remove?
Note I loosened the 3 smaller bolts that secure the plate. Just reinstalled them when I took pic to try again next week.

Get some PB Blaster on there and let it soak in.

Not a left hand thread, so you're turning it the right way. Not doing anything wrong, I just think you've got yourself a super-tight one. Is it turning the whole nut/bolt as one, or frozen solid?

First thought is to make sure your impact has a full battery (if electric and cordless).

On the other side, make sure you have a really rigid connection holding the head of the bolt. If it's not solid that could be soaking up a lot of the impact force. Typically I put a closed-end wrench on it and allow that to lever on something solid, the back of the hub, maybe.

Can try hitting it a little with the impact in the tighten direction, then flip it and see if that breaks whatever's in there that's keeping it from moving.

May end up needing a breaker bar and more leverage.

I used an about a 34 inch breaker bar and doesn’t budge. It is staying frozen solid when trying to loosen. And what do you mean it’s not a left hand thread? Wouldn’t trying to loosen the nut mean spinning towards me if I’m facing the wheel? Meaning the nut would have to spin left if looking thru the picture

Might have to try that method, the wd40 I used was not meant for threads and I didn’t have any other penetrants. Will try again next week

Shouldn't have mentioned left hand thread, as it's not left hand anyway. Maybe on a "changing lawnmower blades" thread, but not this one.
Standard is right hand (counter-clockwise to loosen). Left hand thread is opposite.

And no luck with a 3' breaker bar is no bueno.

I'd say heat, but I think there may be rubber or something that could melt/deform in that shock mount, not sure.

Only other thought is a weighted socket. But if a big breaker bar couldn't move it then a weighted socket could end up being a waste of $.

Worst case, grind and replace. But hoping it will finally give up before that.

I second soaking it w PB Blaster, worked wonders when I've used it several times. It's part of the fun wrenching on the 50+ year old 240Z when I owned it.

My passenger side front was a bear. I used a breaker bar and just kept working it. At first I thought it wasnt coming loose, spent at least 45 mins on it. Eventually through sheer determination
did we get it to budge.

It's 110 ft lbs torque spec so, quite tight. I used a ~3 ft breaker bar when I did it.
