    Strut top bearing / mount

    Question for the knowledgeable. I was doing a ball jolint inspection, and did the wiggle test. I grabbed the tire at 12 and 6 o'clock, and tried wiggling it in and out. The ball joints, and control arm bushings are fine. But, I noticed movement at the top strut mount / bearing. Not where it mounts to the car with the three bolts, but where the strut shaft goes through it. Is this normal? Is it supposed to move? Supposed to be stationary at all times? Any advice would be appreciated. Thanks

    There should not be any movement at the top (or the bottom!). You should be able to see at least 3 full threads above the nut that clamps the bearing case to the strut shaft; the torque on that nut is 55 lb ft.

    The torque on the three strut tower bolts is 35 lb ft.

    Good luck.

    A word of caution, check your fsm for the correct torque on the three
    strut mount studs. I just installed a pair on my 94 DeVille and tried to torque
    them at 35 ft. lbs. and wrung one off and then found the correct torque to be 18 ft. lbs.
