I can barely move the left rear lever arm. That’s the side with the broken link. I haven’t had time to disconnect the link on the passenger side to test that lever shock. It took my weight, 200 lbs, hanging on the lever to get it to move at all. Does that sound about normal since the car is a lot heavier? Possibly the link broke because of age and it just finally failed? I noticed the right rear link has been welded at some point and it had failed at the same location in the link.

That does not sound normal to me.

Hello Tom What is normal in this case? Would it be the amount of resistance like I experienced, or should I be able to work the lever up and down more easily? Also how does a shock like this "freeze"?

I don't know how strong you are, but my strength is probably average for an 87 year old and I am able to move the arm on a shock in both directions while laying underneath the car or from the wheel well with the tire off. As guess, I would say that the resistance is between 30-50# in both directions. A shock becomes frozen when it runs out of fluid and corrosion sets in.

Thanks for your response. I’ve checked the fluid level and it’s full. If you can pull/push on the lever and it moves that easily then something else must be going on. While hanging on the lever with the weight of my upper body and pulling down with both arms the lever will barely move. Pushing up results in the same outcome. I’ll try working the lever up/down to see if it gets easier. I’m wondering if air got trapped in there somehow.

Air isn't your problem as it is far more compressible than shock fluid. It it obvious that your shock is not functional as intended and it has led to the failure of the shock link and likely the cause of the list of your rear end. Remove the shock and send it to Andy Falandes (andys.shokx@gmail.com) to see if it can be saved.

The shock may have been filled after it failed for the PO. I agree with 3w2 that you should have all of your shocks rebuilt. The ride will be more comfortable and the car will handle better. Bad shock can make it a chore to drive the car.

Yeah that’s where I’m headed. I’m going to check the right rear shock for comparison before I contact the source you gave me,when I return home. Thanks for your help.

If the arm moves with your 200# I suggest you try adjusting the shock by moving the adjuster CCW a small amount, to get it to move more freely. If it remains very hard or leaks a rebuild is in order.

Finally have gotten time to return to this project. I have tried what you suggested but the end of the leave spring still contacts the broken link. Do I also have to remove the two flat pieces and let the spring hang there while I try to drive the broken link out of its hole? I've been trying for days to remove the other end of the broken link from the lever and have been unsuccessful. Penetrating oil hasn't worked and today I tried heating it and that didn't work. It acts like the bushing and pin have rust welded together. Obviously I'm concerned about removing the other piece from under the car even after I get the clearance to do it. Thanks in advance for your input.
