I have this down to a fine art. We have a 10,000kgf press and access to a 100t, this is a better method sometimes when the part is awkward or lacking in meat to press against, like T1 and T2 balljoint cups for example. 1 slow bead with a MIG and leave it to cool for 5-10 minutes. 1 blow with a hammer isn't unusual. The amount of shrinkage can be impressive.
UK readers note 'signs of excessive heat being applied to suspension or steering components' is an MOT faliure.
