hey, I have been fighting with my lower control arm bolt(that goes thought the Shock) to remove it and install my new suspension.

I've tried so far:

-Using a standard breaker bar and ratchet set
-using my dads air gun

it will move a bit but I'm scared that if I force it too much, I'll snap the bolt.

I've heard that If I put brake fluid on both ends of the bolt and leave it for a while, that it will sink into the threads and allow me to un-screw the bolt.
Is that true??? any other suggestions???

I believe this bolt is seized in there so I need to get it out asap before Saturday.


thanks

soak it in some good penetrant like pb blaster. work the threads back and forth with a breaker bar slowly.

 

On my car, i had all teh bolts on the rear seize to the lca, and even parts of the trailling arm. If you live in a climate that snows etc, i would expect it.

If you tried all the above, and the bolt isn't turning, it could be seized. even IF the bolt turns, it still could be welded by rust to the sleeve inside rendering your bushings bad.

What i had to do was change out my entire rear suspension including the lca, and trailing arms.

PB Blaster does wonders, but after soaking the lca with it, as well as using a torch, it was a no go.

 

When they feel like they are turning a little then not coming out, that usually means the bolt is siezed to the steel sleeve in the bushing. It might come out with penetrant, but I would expect it won't. Be prepared to replace the bushings and the bolts. I ended up cutting the bolts off and pressing out the old bushing and pressing in new ones. You can get new bushings for the LCA without having to replace the whole arm.

 

ok, thanks guys.

But how much does like a new bolt and bushing cost????
