New member here, what a great wealth of knowledge here. My latest project on my avalanche turned into quite a nightmare. I had issues getting the hub out of knuckle like most everyone, I was expecting that. Took me about 45 minutes to free it. What took me by surprise is I couldn't get the shaft out of the hub. Its still stuck and won't ever come off. I got the but off and tried an air hammer first. Mine is anemic so I didn't get very far with it. So I tried a 2 lb sledge. I was trying to be careful not to damage the threads on the CV shaft so I put the but back on. The shaft wouldn't budge. I figured a heavier hammer would help, so I stepped up to a 10 lb sledge. The carnage from that can be seen below.





It amazes me the shaft didn't move. I heated the bearing up twice before most of the damage to the end of the shaft happened. I didn't want to buy a new shaft, but bit the bullet. Luckily there was no core on the shaft.


The wreckage from the mighty blue wrench can be seen here.





I just kept gouging and trimming til I had a mound of molten metal on the floor. I did recruit the help of a skilled surgeon at the end and he snipped the races inside and what was left of the hub fell off. Everything went together real quick and I made sure to use anti seize.

The whole project took 2 nights after work instead of just an hour or 2 like it should have. I live in Maine so the salty roads in the winter wreaks havoc on vehicles.

Thanks for checking out my nightmare.

I live in the northeast. The salt the road crews use in the winter to break up snow and ice on the road really rusts stuff up. The axle was rusted into the hub.

Snow isn't the problem, salt is. Why can't these municipalities go back to using sand? I would much rather drive on a snow and sand covered surface rather than a salt/slush covered road. But that's just my opinion, some people just buy new vehicles every few years and never see the affect of salt over the years.

Onterrible uses more road salt per mile than anywhere else. Never seen that, not even on the stock shafts in my OBS, after 20years of plowing and salting.

That's nuts, the inner was fully unbolted and dropped first?

My avalanche was run up and down the interstate (which uses only salt and salt brine) for its first 120000 miles. My hood is weird. Where the striker plate is, is rotting out. Where the hinges bolt to the underside of the hood is so tender, its going to pop through soon. The outside of the hood looks perfect. I think the slush and salty water was caked on the front of the hood and ran down the rails and sat in the hood hinge wells and just rotted it out.

Im in the saltbelt as well and never have seen something that bad. Its like they used something corrosive when it was installed. But i def. Would have chopped the cv shaft within 10 minutes of it not coming out. Lol

I have done others on cars that came right out too. I am pretty sure that was the original hub, so 200000 miles and 10 years is a long time to rust together.

I've been saying this for years. Salt is the devil. But I LOVE snow!!

Haven't even got the sled out this year:
