I'm replacing the front springs and shocks due to a broken spring on the left side and a lot of visible rust on the shocks. By the guides I've seen online this requires separating the hub from the driveshaft, but on both sides the hub bolts are incredibly stuck. I've tried soaking with penetrating oil (multiple applications over a couple days), heat with a heat gun and induction heater, air powered impact driver, air hammer on the end of the bolt and a 2m long extension arm(broke the 1/2" square connection on the breaker bar). I have replacement bolts but am usure how to do destructive removal in an effective way(would drilling possibly be an option? Cannot access the bolt head in the direction to cut it off without destroying the hub also). Does anyone have tips on either bolt removal or how to replace the shocks without removing the hubs? The bolt heads are still good so torque can be applied, see picture.

Welcome to the forum.

Are these hub-bolts 'handed' - I.e. LH thread on the left hubs?

typo

Borrow a 3/4" sq breaker bar and adaptor to 1/2".

Or 3/4" socket too.
