failed rear axle bushes will cause vague and 'wadery' steering and/or knocking
Any proven methods to test? I had it up on the ramps last weekend with a giant lever in and around most suspension components checking for slack/play - but couldn't see anything moving.
TBH our MOT tester failed it for excessive play on the MOT, as the inner rubber bushes had fallen apart in 3 pieces resulting in a lot of play. the rear axle was floating a fair but so the car would track dangerously and i was constantly correcting it with the steering wheel. It was as if it had rear wheel steering

I'd stopped driving it for 10 days prior to the MOT test as i felt it was dangerous.
I assume he used his big bar and prised the beam to check for play
