They've been soaking for 2 days actually... lol. I pulled the truck in on Friday after work and soaked everything down. Saturday I pulled everything out down to the cross member and soaked the trans bolts again. So today was to pull that and drop the trans, swap out everything and slap it all back together. Co-worker said he's never done one and wanted to stop by and help today... so much for that, never showed.
I got it finally, I was about to call it a day and start plans to pull the motor when I remembered that I had gotten a 1/4" angle air grinder for christmas from my parents. I had to pull the driver's side exhaust manifold off and 30 mins of grinding later the bolt head is gone. And then to throw salt onto the wound, one of my creeper casters burst apart while in the middle of it. So I spent the rest of the time sliding around on the concrete.
All but the bottom 2, 14mm bolts are shot. Imagine that, those were the ones I could get with the impact... rofl. The 17mm ones are fine, though I almost busted my hand open on one of them. Good thing I had gloves.
I'm going down tomorrow and picking up a stud puller to take out what's left of the bolt. BTW the source of all my noise... my bearing sounded like that bolt I just ground off when I spun it.
