Lover control arm bolt stuck halfway out and not moving. Nut and washer is missing. Can’t get it out or alight the wholes

[Maxmax19773]

Hi guys , need your wisdom) my Lowe control arm bolt is half way out and nut and this fancy washer is missing. Bold stock and not moving in any direction. I believe this is the part where CA attached to the frame or its most likely subframe. I attached pictures. I was trying to jack it to take bolt out with no success. Do I have to release the torsion bar? Is there any procedure that align these holes and take bolt in or out? Plan is ( if treads are still there then find the nut and put everything back together. And what about washer or whatever it is missing?? What to do about that? Just put regular washer and search for used one ? To attach pictures of the driver side with misaligned holes and bolt halfway outb. And another picture is the right side for reference on the washer or whatever it is called. Thanks god I was removing radiator to replace the wire harness on crank sensor and discovered it . Thank everyone in advance. Max

Do I have to release the torsion bar?

Yes, the torsion bar has to be fully released to get the bolt out/in.
Releasing with a tool is the savest way.

Nut part number should be N808166-S441

Youll need to get a floor jack under that arm, And loosen the torsion bar like @wollimann says. Make sure to count the turns as you unbolt it to approximate your ride height and preload. I just wrote mine with paint marker on the frame.

after you loosen the bolt for the torsion bar adjustment, you can lower the control arm with the jack and swing it down, it will alieve the spring tension and allow you to remove the torsion bar.

First remove the cover plate

Be careful, lot of preload! You can use a two arm puller but you have to secure it
so it can't be slip off!

Awesome. Thank you! I was removing them few years back, my 2 jaw puller didn’t work on them well, do you know the part number of tool you posted before? Thank you for stepping in. I already purchased the washer from eBay.

If you support the control arm with a hydraulic jack, loosen the adjustment screw on the torsion bar all the way out, remove the lower balljoint, and slowly let down the jack. (as long as the vehicle is on jack stands and high enough) you can relieve all tension on the torsion bar without the tool.

Just remember when re-installing that you will have to use the jack to put the control arm back into place. once in place, you can re-install the lower balljoint and tension the torsion bar to spec. If you are not comfortable with any of these steps, please purchase the tool. you are dealing with a loaded spring, and metal is un-forgiving.

Here is the tool wollimann was talking about

and while your in there, you can replace these:

These are the rubber pads that crumble behind the torsion bar and isolate vibrations

What i bought was the OTC 7826, hope your tool is wide enough to slide over the frame.
