Trying to get the blazer ready for Harlan, installed 4" lift, and realized the front driveshaft has seized up in the splines. Never seen this before, so I put the heat on it and try to beat it off, with no luck. I've not had the blazer for the past 2 years, and got it back with the rear end out of it. I cant imagine why it wont move, but the more I think about it, could the splines be twisted? Any ideas?
