howeitsdone Posted July 12, 2021 Share Posted July 12, 2021 Hi all, So I've removed the 3 bolts on the back of the knuckle, the caliper, and axle nut. I started taking the BFH and lightly tapped around the hub to loosen. Didn't work. So then I tried using a punch on the back side. Didn't work. My last resort was putting the rotor on backwards and taking the BFH to earn it's name. Didn't work. Actually it started chipping the rotor so I stopped. Everything has been sprayed down continuously for a couple of weeks now. Is there a particular tool anyone could recommend for a rust bond this bad? I'm going to replace the hub at this point, but I don't even think the old nut & bolt trick will work. Link to comment Share on other sites More sharing options...
Pete M Posted July 12, 2021 Share Posted July 12, 2021 you can use a bolt to brace as shown and then use the power steering to push it out. I recommend having a second person to do the steering while you watch the progress. Link to comment Share on other sites More sharing options...
jdog Posted July 12, 2021 Share Posted July 12, 2021 But I put it on one of the three bolts partially threaded in Link to comment Share on other sites More sharing options...
Pete M Posted July 12, 2021 Share Posted July 12, 2021 I used to have a picture of that too, but cannot find it. Link to comment Share on other sites More sharing options...
87MJTIM Posted July 12, 2021 Share Posted July 12, 2021 HEAT is your friend! Can you get a propane torch close to the contact surfaces? Link to comment Share on other sites More sharing options...

Next time for sure. 3 hours ago, 87MJTIM said: HEAT is your friend! Can you get a propane torch close to the contact surfaces? I think so. I believe propane won't get that hub hot enough (700) but I can at least give it a go. Would you do this in conjunction with a specific tool? There are quite a few pullers out there.

There are quite a few pullers out there. A 10 lb slide hammer and a hub puller. Acetylene torch is hotter than propane, but not as hot as Oxy-acetylene.

watchamakalit Posted July 13, 2021 Share Posted July 13, 2021 Heat. pb blaster. Bfh. Not sure what else to suggest. I have always used the power steering method on the really stuck ones. If your brave you could try bolting the wheel back on and setting the weight of the truck back on it. Not sure it will work but the weight of the truck might be enough to pop it loose.

Minuit Posted July 13, 2021 Share Posted July 13, 2021 Have you tried hitting it with your purse? For a real answer, I would try heat and a slide hammer first, with putting it back together and using the power steering (CAREFULLY, and WITH THE TRUCK VERY WELL SUPPORTED) as a second option. In case you haven't done this much before, remember to concentrate most of your heat on the outside part. You may also try combining this with cooling the inside part with water from a spray bottle to both expand the knuckle and contract the hub.

Big Dan Posted July 13, 2021 Share Posted July 13, 2021 For reference, the "outside" part as in the surface where the studs are and not the splines of the hub? Sent from my Pixel 4 XL using Tapatalk Link to comment Share on other sites More sharing options...
