siezed bolts

Anyone have any ideas how I can unsieze the rear hub bolt which goes through both lateral arms. Otherwise my grinders coming out. Have the arms free at one end but the long bolt through the hub feels siezed into the metal collar.

Or Bob if you have any arms ill just cut these off and buy some replacement ones

Use heat blow torch etc

yep as above
but some will not shift even with oxy setylene on them, they can be virtually impossible to budge on some cars
if needed ive got good bolts etc if you wanna cut them off

Had same problem on a mazda 323 B6T some time ago. whole hub/arms came off & seized bolt got dipped in duck oil over night & then assembly went in bench press & was left under load over the day. once could see it had moved a bit we increased pressure & it slowly came out.
Was done as non destructively as possible due to cost & difficulty of part sourcing on that model.

Tried again tonight but no joy, the fuckers getting cut off tomorrow. Bob you open Saturday's any more as ill swing buy, still need to pay for the catch tank aswell

Managed to remove the bolt yesterday and finish stripping the arms/hubs. Was a right pain and had to be cut in the end so will need a new one bob

yep pop up mark as we have bolts down here
we were open Saturday but didn't see the message till now.
may possibly be open this coming Saturday but wont know till later in the week
