Hi, on-going topic, the long rear suspension bolts.
One bolt I couldn't remove so removed the rear hub with strut and an arm attached. Angle ground the arm off, pausing to check heat transfer levels. The angle ground the strut off and the removed remaing exposed segements of the bolt. Despite all this, those segments are still stuck fast.
My debate now is whether to drill or press these segments out. Press wise, am considering loading up from the outside, on both segments at the same time and pressing inwards, using short M8 bolts to press on the segments rather than the hub. Any change the hub will bend though? What ever the inter-metallic reaction between bolt and hub, these things seem effectively welded together.
Drilling is not going to be easy as these are high-grade hardened steel. Cobalt drill bit or should HSS be enough?
My car has been on 3 wheels for several days now so would be good to get this sorted, somehow...
Thanks in advance.
