not long before my kid got his k11 the previous owner had the rear axle replaced,as it rotted and collapsed on the nearside.and the car i sourced some goodies from a few weeks ago had died from same thing.ive had a scout around the forum to see if anyone else has had this issue,as im gonna weld in some strengthening on my kids k11s' rear axle.so is it a common issue or am i just being a bit'belt and braces'?
