ya i also used 1/2 can of pb blaster. Although I didn't let it sit more than 1/2 hour at a time, I think it still helped. A friend of mine suggested pb blaster and letting it sit a few days then hit it again and keep doing the same process for a couple weeks then try doing the repair. He also suggested just taking the cv halfshaft out with the bearing still on it and using a press to get it off. Either way, I honestly think it was worth the extra $60 to get a new cv halfshaft and just replace the whole ****. Was a $60 well spent IMO.
