Default progress report: replacing LCA bushings and wheel bearing

The original post starts below, this is what I added later.

This project started with unexpected problems, and I am expecting more. I guess I need to come back to this forum for more advices, let me thank all PTer in advance. So let me put everything together in this progress report, hopefully, others can find something useful here.

BTW, please forgive me if some of my questions are so naive. This is just my 3rd DIY project. Oil change is the 1st, I then replaced all brake pads and rear brake rotors as the 2nd.

I am currently working on replacing the bushings in both lower control arms. The first step is to loosen the anti-sway bar links. The picture below shows the nuts of the links, it looks round, but is actually not, its size is between 1-1/8 and 1-1/4, not standard, so I have to use an adjustable wrench. It does not work, probably because it's too rusty. I tried WD40 to no avail. I can't even loosen the links, let alone the bushings.

I am thinking of remove the anti-sway bar all together with the lower control arms, but I trust your guys always have some great advices.

Thank you very much.

PS: The replacement links I bought from Moog have regular nuts.

You can try with a vise-grip or just cut them, if your kit has new bolts.

It's time for the hack saw. You may scrape you knuckles with a vice grip.

I bought this grip.



It's very tight, the nut never slipped even if the link bolts broke under torsion.



You see how rusty it is. My 03 PT Limited is not driven much by its previous owner. When I bought it in 2010, it had <18K miles. So a lot of rust develops. Last year I had to replace pads and rotors in the rear because there was too much rust, one side of the caliper did not move.

This time, the bolts gave in before the rust gave in.

Now I end up with the broken link bolts on both ends of the anti-sway bar. Do you know what I should do to remove it? I checked the service manual, which does not mention any special procedures needed to remove it, so I guess it should be a piece-of-cake job if it's not badly rusted.



I also checked Xwing777's post, he did not say anything about the link bolt either, so I guess he did not have this problem. Here is his picture.

With the anti-sway bar link bolts hanging there, now I have another two rusty ones, those which hold the ball joints in place. I soaked them with WD40, still can not turn them even a little bit.

I have to give up this project and send my PT to a shop. To replace LCA bushings and a wheel bearing, a shop charged me $500 for labor, I will bring the parts. I was thinking of saving the labor fee by DIY, the God blessed rusty bolts set me back.

I will drive my PT to the shop with the anti-sway bar hanging loose down there, I guess it should not be a big problem.

When I was under the car, I took a few pictures about the rust. For a 2003 PT in Michigan, is it badly rusted or just about normal?

Thank you.

That's a lot of rust, IMO...I would remove all that rust and treat it with some rust converter and undercoating before is too late..

Thanks for letting me know. I will send it to a rustproof shop, I don't feel confident to DIY.
