I'm in the same boat but I am about to change the lower arm and on checking I can see the inner plastic guard has some rub marks (clean bits) that the upper head of the drop link attached to the shock is touching it during travel that means the top of the shock is bolted in incorrectly positioned or not centre maybe not tight enough or the bushes on the bottom arm are allowing too much movement I also found that there was noise coming from the brake pipes that had become unclipped underneath parallel to the cat/middle box and slapping on the floor from underneath any other noise like exhaust rasping check the heat shielding all along the exhaust deep standing water tends to fold it in against the exhaust pipework especially where the joint would be before the back box if it has been replaced. Just waiting for dry day with daylight and some time. To date new shock, top bearing and mount, inner and outer track rod ends and checked for play in the steering rack during the change. All that's left is anti roll bar bushings and lower arms the hub upper and lower ball joints have no play. Failing that I will have to check all sub frame bolts the gearbox mount was changed in the last year and exhaust is totally standard except one flexi mesh that's going but no blowing out yet.
