2419.0. "sideways/crab cars" by BAHTAT::HILTON (Beer...now there's a temporary solution) Tue Jun 13 1995 23:28

    What happens to cars to make them appear to be driving 'sideways'.
    
    
    Over the years I've seen the odd car, where the back wheels seem to be
    offset to the left or right of the front wheels, giving the impression
    the car is crabbing or driving sideways.
    
    I've seen this mostly on old Minis.
    
    What's happenned? Has the car been bent in an accident?? Is it illegal?
    Has anyone else seen it?
    
    
    Cheers,

    Over here in Canada it's most commonly referred to as
    dog-tracking...watch a dog run for an explanation of the term.....
    
    It is caused (at least on North American cars with live axles) by one
    side of the axle coming loose a slipping a bit.

    Yes - but only when I'm driving - ask anyone who's been with me when
    I'm in a hurry.

2419.4my thoughts on 'crabbing'...WOTVAX::STONEGTemperature Drop in Downtime Winterland....Wed Jun 14 1995 13:178
    
    On Minis the most common cause is a bent or broken rear sub-frame, it
    wouldn't fail an MOT because of how it looked on the road, but if the
    sub-frame is obviously damaged then it should. On more modern cars,
    there must be a serious suspension alignment problem or else it's been
    in an accident and not been re-built properly.

    re.Mini's and 'crabbing'
    
    ....or worn/shot trailing arms. Same with Metros too. Both cars are
    very particular about having their trailing arms kept well greased, but
    not all people bother 'topping them up'. Hence they wear out and you
    get this rather amusing looking driving stance!

2419.7Carbbier than your average car!TOMMII::RDAVIESAmateur ExpertThu Jun 15 1995 19:165
However, if you look at the Citroen Xm or CX they look like 
they're crabbing from whichever side you view them. This is 
'cos they've got a wider trach front than rear!

2419.8misalignment of rear axle mounts!CTUADM::MALONEAlways ObtuseSat Jun 17 1995 03:2612
    I've seen this on recent cars, produces by the big three bang-em-out as
    quick as you can econo-box makers.  Probably a Monday morning(What a
    hang over), or Friday afternoon(Let's get a hangover) construct.  Even
    with automation, there still seems to be room for error during
    construction.  If the rear axle mounts are off a little, alignment can
    correct and center the car for directional stability, but you end up
    with dog-tracking.  If you can catch it(tough since you just really
    never see your back end as it scoots down the highway), you more than
    likely can get it repaired under warranty.

    It should be easy to see this. Drive the car in a straight line through
    a puddle. Look at the tracks it makes after the puddle. If the car is
    misaligned the rear tracks will be offset from the front tracks.

    ...Provided the puddle is wide enough and the puddle is surrounded by dry
