I can't get to the head of my rear spring bolts on on the heads. It is resting in the trailing arm frame area. I tried to jack it out but it doesn't move (obviously). I like to unbolt things, but I'm probably just going to have to cut it in half and push it out the top. I just don't like cutting things. Any other course of action?

One other little question, how many pistons are in our rear calipers? I thought they were single piston but mine are double, or atleast look like it.

Schmucker,

Use Vice Grips on the shaft of the bolt to keep it from turning.

Be sure to use a c-clamp or vice grips on the spring to keep the jack from slipping.

Total of four pistons in each brake caliper. Fixed calipers with two pistons mounted on either side of the rotor. Caliper does not move.

4 each :thumbs: 16 pistons in every C3 :yesnod:

Only if you have the metal spring. Don't try this trick on the fiberglass.

I'm not exactly sure what bolts you mean, but to get at the long bolts at the ends of the spring, I took the rear sway bar ends off the trailing arms, and was able to fit (barely) a wrench inside to hold the head of the bolt.

Yeah - I don't have the rear sway bar - so I thought just insert a box end
wrench into the end of the TA. (my recollection may be cloudy)

:seeya

I'd do that but the head is too far into the trailing arm. I'll try the Vice grips trick, just I don't like that I had just returned the ones I had borrowed! I'll run to my mom's hardware store and get my own. They are too useful.

O/a torch is how I did it. But thats only because the top washer was rusted to the bolt, almost like a weld....

Schmucker

I GOT THEM! The vice grip trick worked wonderfully. They came right off after I got them loose. Problem I'm having now is that the differential spring bolts are very solid. I can't move them. I sprayed some PB Blaster on them and air brushed on the threads to clean them up. I need a body builder to help me out. Any ideas now?

Call me paranoid but....While you are under there, cranking, yanking and banging away, please make sure that the car is solidly supported!

NHvette

Even good air tools can have trouble breaking a seasoned spring bolt loose.
Feel lucky. Two of mine were broken off and the remaining two were bent. :eek:

Go back to the hardware store and get about 3 feet of iron pipe that fits
over the handle of your biggest ratchet/breaker bar. 3 feet of leverage can
coax even the most difficult bolts. Let the blaster soak in there for a few days ...
don't want to snap 'em off.

Good luck :seeya

Yeah, I have three different pipes but I'll be damned if none of them fit over the wrench!

And yes the car is solidly supported. We attempted to push it off the stands and it won't push off the stands.
