    Default Rear control arm bolt size

    I was browsing under my car and noticed one of the rear control arm bolts was missing, looked on google and here trying to find the dimenstions of the bolt but couldent find it.
    does any one know the specs?

    I think this is what you need. It's a 1.5 thread and the bolt is 21.77 mm in diameter. Thats 57/64". Threaded portion is 1.15" long.

    If you are referring to the smaller hardware on the hanging plates and U clamps or the differential/control arm cross member that hold the control arms:

    Take another out then go to hardware store (in another car) or order from nissan

    Apart from the big beastie in the photo above, I think most are M8 and M10... not sure of thread... usually 1.25 but could be 1.5 so buy both threads if at a hardware store.

    The other bolts that Blue mentioned are M10 fine thread (1.25mm)
    I ended up buying a whole box of them when I was working on my car because the original bolts were so rusted in place that they all snapped off when I tried to remove them.

    You could also check the link below. I've changed all the suspension bolts on my Z, so the dimensions are known to be accurate (except for strut nuts)

    Sorry to bring up an old thread, but I have lost one of these large bolts. I cannot find them online or in any local hardware stores. The size is M22 x 1.50 x 30. Does anyone have one, or know where I can get one? I need the big washer and the toothed ring, too.

    Thanks,

    Matt

    Bug Zs-ondabrain again, he's still kicking and knowing him, he has some still. Send him a PM.

    I have a few as well, just not as close! Let me know if you need one.

    I just found a few of those bolts and I think I have some washers too. Email if you need them.
