I changed the rear subframe bushes the other day and noticed that one of the rear shock absorbers has been leaking oil badly. The thing is, all of the shock absorbers on the car pass the bounce test as per the MOT examination but I have to say the whole car feels wobbly over poor surfaces these days , no clonks or anything from arms etc just a feeling of instability..... The car has now done 213k and the shocks/springs are the factory originals, so really think I should invest in 4 new shocks at least. Question is should I renew the springs also? Don't want to lower the car at all so don't know if I should keep the old springs (which admittedly look very rusty and crusty) with new shock absorbers or fit new shocks and stock-length springs? Thanks.
