She was drydocked adjacent to "Iéna" on 12 March 1907 at Toulon when the latter ship's magazine exploded. Burning fragments started a small fire aboard "Suffren", but she was not otherwise damaged by the explosion and participated in the annual fleet manoeuvres that began on 1 July. By 5 November, the ship had been replaced as flagship by the semi-dreadnought , although she remained assigned to the 1re Division cuirassée (1st Battle Division). In early 1908 a Barr and Stroud rangefinder was mounted on the navigation bridge. "Suffren" was transferred to the 3e Division cuirassée in July. During manoeuvres off Golfe-Juan on 13 August, the ship's port propeller shaft broke and the propeller fell off in water deep. While a new shaft was ordered from Indret, "Iéna"s salvaged corresponding shaft was used with such success that the ship's engineers requested to keep it in place and save the new shaft as a spare. This proposal was rejected by the Naval Ministry and the shafts were exchanged. The opportunity was also taken to rework the centre propeller shaft's mounting so that it would overheat less often. In 1909 the battleships of the Escadre de la Méditerranée were reorganised into two Escadre de ligne (battle squadrons), each with a pair of three-ship divisions; the 3e Division cuirassée now assigned to the 2e Escadre de ligne. "Suffren", as the most modern of the predreadnoughts, was often attached to the 1re Escadre de ligne to replace ships that were refitting or under repair. In November 1910 the starboard propeller shaft broke and the propeller was lost in deep water. No shaft was immediately available so "Suffren" had to wait three months for repairs; her boilers were overhauled while a new one was manufactured. On 14 February 1911 the port anchor chain broke while "Suffren" was conducting towing exercises with two other battleships, killing one sailor and injuring two others. The ship participated in a naval review near Toulon on 4 September. The Escadre de la Méditerranée was renamed the 1er Armée Navale (1st Naval Army) on 31 October as the Marine Nationale concentrated its forces in the Mediterranean.
