Vehicle is a '93 Blazer Cheyenne.
I'm replacing my front hub assemblies. All bolts on the driver's side unit came out of the knuckle just fine. I've been fighting tooth and nail to get the passenger's side bolts out though. I did manage to get one out after soaking in PB Blaster overnight. The other 2 are not budging though. I've let my Makita impact wrench crank on it a lot, and am using a good 6-point impact socket to get really solid purchase.
I have replacement Dorman class 10.9 bolts waiting to go in with the new units, but don't know what class or grade the original bolts are. I'm hesitant to sit on a breaker bar for fear that I'm going to snap these suckers off in the knuckle then have to suffer new extraction problems.
Any ideas how much muscle the original hub mounting bolts can handle?
