I’m trying to replace the CV axle on my wife’s 2006 Chevy Malibu, and the project is frozen in its track by a seized bolt.
Specifically, the top bolt of the two bolts that hold the steering knuckle to the strut. I got the nuts off the other end of each bolt with a breaker bar no problem. I set a jack under the steering knuckle and raised it a bit to relieve any load on the bolts, and with some PB blaster and a hammer, I got the bottom bolt out.
But this top bolt just will not budge. I’ve drenched the thing in PB and pounded the living hell out of it all to no avail. I don’t have any socket that will fit the bolt head and besides, it’s not really threaded in there. I don’t have an air compressor or impact tools. The only thing I can think to do now is to get a torch and try to heat up the metal around the bolt head to maybe loosen it up some.
One way or the other the bolt has to come out now because I’ve mushroomed the other end of it with the hammer and a nut won’t go back on it. If anyone has any thoughts, I’d love to hear them. Thanks!
