    I have a vibration coming from the top of the Air Filter Housing when I'm in drive and brake for a stop. When braked and in drive, it idles just around 600 rpm and vibrates. When I put it in P or N it idles around 650ish with no vibration. I know it's the housing because I had my wife get in the driver seat and go back in forth while was inspecting the engine compartment. As soon as I held and pushed down a bit, the vibration went away... at least until she put it in park again and back to drive.

    This is driving me nuts... I've tightened all the mounts but no go... anyone have this before?

    Thanks

    No, never heard of it.

    Maybe a snorkel will make the vibration go away?


    :D

    Is the wingnut on top tight?

    do you have an OEM filter? the Toyota one fits tight in there, others may not. have you looked at the tuna can? coudl be something in there or in the main filter housing

    95 does not have a pair valve correct?

    No PAIR valve. Agree on wingnut, filter brand questions. There's nothing to rattle with a factory filter, the three clamps engaged, the tuna can clamps engaged and the wingnut tight. Unless you bought it used and that's the diamond studded money clip full of G notes the previous owner left in his hidey spot...

    I have the exact same vibration....when I come to a stop while in drive. However, I think the vibration is actually coming from the plastic air intake assembly inside the RT front quarter panel. There must be a mounting bolt missing or something out of alignment there but because I haven't been able to access I've just been ignoring it.....

    The heat shield down low may be touching the fender and causing it to vibrate. I have the same issue sometimes since opening up the exhaust.

    The wing nut is tight and the filter is OEM. When the engine idles when stopped, the engine vibrates more than it would while in park or neutral, because of that, it is vibrating the intake hose that connects to the top of the filter housing. The vibration isn't like a hign pitched rattling but a deep motion vibration. You would think it was just the engine by feeling it, but it's not... I did verify the motion... while pressing on the top of the filter housing. Again the wing nut is as tight as I can get it.

    Not sure I know what the Tuna can is... would that be the small 'can' at the bottom of the housing?

    I'm getting an odd noise now in my wife's 80.

    :hmm:

    I wonder if this might be the issue.
    The "rattle" is coming from the front PS of the rig -- according the the :princess:, it's toward the front of the vehicle.

    I'll need to take a closer look this weekend. I'll report back to this thread on what I find and what, if anything I can do to resolve the issue.

    FWIW -- I got the same symptoms in my rig, and haven't pinpointed the exact location of it yet.

    I do have my intake for my York OBA system plumbed to the bottom of the filter can though so the fitting could be the cause of my vibration. I'll dig back into it and see if I can help find the problem.

    Had the same type of vibe, but it ended up being the OEM bumper corner. Both of them were missing the bolt holding it to the bracket. New bolts, that noise is gone. Too bad i discovered a few other ones :doh:
