doga-ot -

i rather stupidly tried to go sideways round this rather tight corner in the snow.
it sounds more stupid than it really was but, long-story-short, i hit the curb and both rear wheels looked just like your photo and it made the car crab ever so slightly!
i corrected the crab with the tracking temporarily but found in the end that it was the diff mount. not so good.

patience and muscle with the diff lowered, a blowtorch and a very big adjustable spanner closed up over the mount straightened it out. YeeHaa! but its still fine today, a few years later.
