johny Posted January 19, 2023 Report Share Posted January 19, 2023 I do like the idea of heating the hub as although Ive never done that in theory its exactly what is needed. Theres no seal or bearing in it to worry about so it can be heated rapidly and, with rotation, evenly (needs a decent torch) to expand while the shaft remains cooler and separates🤔 Link to comment Share on other sites More sharing options...

Pete Still do that expt, or did when I was teaching. Plus other similar perennial expts. But I am not certain it is expansion that does the trick. I have only recently had to weld a spanner to a bolt head (a long take of woe!) and the heat released the bolt. But with expansion, it should have been held tighter. The lump of steel it was wound into was large and the localised heat would not have expanded that much, in fact it would probably have gripped tighter. So I reckon heat just causes a bit of movement between the two parts, releasing the grip. Similar to hitting fastners with a hammer to shock them before attempting to undo them.

sulzerman Posted January 20, 2023 Report Share Posted January 20, 2023 I've removed several hubs with the correct tool. Wind up the pressure with the tool and give the flange a good whack with a punch and lump hammer. Never had a problem, always comes off no problem.

Jeffds1360 Posted January 21, 2023 Report Share Posted January 21, 2023 It is 2yrs since I needed to repair mine. For some reason I ended up with the 30" wrecking bar and socket resting on the floor and 24" stilsons (on the top hat) in my hand pressing down from waist level when the joint gave and I fell onto the concrete floor Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 21, 2023 Report Share Posted January 21, 2023 using a reaction bar/grips whatever is well worth as the hub wants to rotate I welded /added a tube to insert a long tommy bar not everyone can lay hands on 36" stillsons ,yes ive used them also Pete Link to comment Share on other sites More sharing options...

Wagger Posted January 22, 2023 Report Share Posted January 22, 2023 Because I was replacing the u/j inserts, I jammed a spanner on the u/j flange. Second side I used a stilson. Yes, I have two massive ones obtained when working for a secondhand tool shop. They 'Accidentally' sold my toolbox when I had a day off. Therefore allowed me free access in compensation. Lesson learned ther was take your tools home every day. Link to comment Share on other sites More sharing options...
SpitfireGeorge Posted February 1, 2023 Author Report Share Posted February 1, 2023 Hi Guys, The hub puller arrived from Rimmers, it is built like a brick chicken house, almost a two handed job to lift it. Put handbrake on and into fourth gear. Put puller securely on and put 30mm socket on centre bolt and wound it in using hand power only. Hub came off! Wow piece of cake. Other side, cannot even undo the drive shaft end bolt! What a bummer. Back to reality. Cheers Link to comment Share on other sites More sharing options...
SpitfireGeorge Posted February 1, 2023 Author Report Share Posted February 1, 2023 Should be drive shaft end nut not bolt, sorry. Link to comment Share on other sites More sharing options...
Wagger Posted February 1, 2023 Report Share Posted February 1, 2023 I used a tight fitting socket, a short extender bar with a 'T' handle. Put a long pipe on both sides of the 'T' bar. Symmetrical torque stops the socket trying to slip off. the nut. Link to comment Share on other sites More sharing options...
SpitfireGeorge Posted February 1, 2023 Author Report Share Posted February 1, 2023 Hi Wagger, Thanks for reply. The problem I have is I cannot stop the shaft revolving when I try to remove the nut. I tried putting a strong screwdriver across the bolts and jammed against the floor but it just bent. Will try a stronger tommy bar next.

johny Posted February 1, 2023 Report Share Posted February 1, 2023 Be very careful you dont distort the hub flange as its soooo easily done. Another alternative might be to put the wheel back on and lower the car onto the ground and chock it so a socket can then be used on the nut...

SpitfireGeorge Posted February 1, 2023 Author Report Share Posted February 1, 2023 Good idea Johny will give it a try this weekend. Cheers Link to comment Share on other sites More sharing options...
PeteH Posted February 2, 2023 Report Share Posted February 2, 2023 Get it hardened as far as you can, whack the Nut/bolt end with a Hammer. The shock is usually enough. As one old Chief Enginner used to tell us. "If at first, you don`t succeed?. Get a bigger hammer"!!.😂 Pete Link to comment Share on other sites More sharing options...
SpitfireGeorge Posted February 13, 2023 Author Report Share Posted February 13, 2023 High Guys, Got the other hub off without dramatics. Jammed a large screwdriver in the universal joint joint and wound in the puller. A large bang and it was loose. Anybody seen some of the frightening hub removals on Youtube? One guy did not initially leave the hub nut on was happily screwing in the puller with his hand resting on it. I moved to the side of the screen on that one to avoid the puller. Another guy was using a hydraulic puller and when the hub let go the combination disappeared at high speed out of sight. Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 14, 2023 Report Share Posted February 14, 2023 and i suspect along with some easily bent flanges Pete Link to comment Share on other sites More sharing options...
