    What size bolts for the front shocks 1991 Grand Marquis? bottom of shock at the lower

    Hi, My drivers side shock is hanging down under the car. Does anyone know which size bolts I need to use to attach the bottom of the shock to the lower control arm?

    Thank you,
    Mike

    1/4" Bolts aren't the issue... The control arms are stripped. You will have to somehow get nuts up there on the top of the control arm.

          Grade 5 will be plenty if you need to buy it. (1/4-20 nuts, bolts and washers on mine).

            Thank you guys.
            I went thru this a couple of years ago and forgot which size bolt I used. I was able to use a paper clip to place the bolt into the shock mount in the lower control arm from the top, then use the nut on the bottom. I hope this is understandable. Since then, I keep large paper clips in the tool box. There is no room to use a tool or hand in the lower control arm.

            Thanks again,
            Mike

                  I had the same problem. I was able to tap the holes out, and install Heli-coils. I let them go past the thickness of the arms, so that the bolts had more bite. I Loc-Tited the inserts in the arm, and let them set for 15 minutes, and then used anti-seize on the bolts when I installed them. So far holding up very well at six months.

                    If I ever have the arms out of mine again, its getting nuts welded to the inside. That should fix it pretty much forever.
