2003 Avalanche Z71 157k miles Right rear wheel got hot enough to almost start smoking, left rear wheel too hot to touch. Could be moisture in the brake lines after having all brake lines replaced last summer but decided to replace the rear wheel bearings anyway first (how hard can it be...). Removed C clips with no problem but getting the bearings out required heating up the axle tubes a bit and beating myself half to death with the slide hammer puller but got the bearings out and new ones in with new seals easily enough after that. Problem now is when I crawled back under to insert the Differential Pinion Gear Shaft I find that somehow the Locking Differential Thrust Block has rotated 90 degrees. The holes for the shaft are no longer next to the side gears and instead are looking at me. At this point I have done just about all I can think of to rotate the thrust block, but I can't see how it rotated in the first place. It is movable but squarish. The only thing I can think of is that somehow if I back off the Latching Bracket I might be able to rotate it. Any insight?
