I have a split cv boot and looking to replace it over the next few days. Any advice, tips, or tricks?

 

Easier to replace the entire shaft vs. replacing the boot.

Most difficult part is removing the hubs from being seized on.

Pretty straight forward....most likely you will be able to re-install the axle shaft and the seal will be OK.

 

I think I found the harder part. Getting the wheel nut off. I've tried everything blow torch, induction heater, impact, and a 4 ft breaker bar which BROKE.

Anyone have advice on how to solve this? I'm at loss.

 

Penetrating oil, heat, oil, heat, oil, heat...longer breaker bar and patience

 

Okay, I've got heat and oil. Just got to get a new breaker bar, and find patience... somewhere...

 

When it's cherry red, rock the breaker bar back and forth (tight/loose/tight/loose)

If you can get a tiny movement it will help the penetrating oil get in there.

Another trick I try is use your flat hammer bit on air hammer and vibrate the axle behind the hub as close as you can to the threaded part

Use flat skinny air hammer bit (if you trust your steadiness!) on tip of axle. You don't want to damage anything just cause vibrations to break loose all the crap you've been working on with torch and penetration oil

In desperate times, I have sharpened a chisel bit for air hammer and notched then walked nut off, sometimes a good punch tight then loose will help

But usually I do exactly what keninnc suggested, over and over.

Also most air impact have 2 stats, the initial break impact and then the follow up impacts. Make sure you oil your gun right before then use the trigger forward and back but just the first 5 impacts so you take advantage of the break/initial impact. It's hard on the gun so oil it before and after

 

This isn’t just Land Rover. My Dodge Dakota hub nuts broke 2 sockets before I got a 3/4 drive breaker bar.

 

3/4" breaker bar with a cheater pipe, or the beefiest impact money will buy. Both work great for those. Common for lots of old stuff with axle nuts, not just these

 

Weld the socket to the end of the broken bar, get a MAP gas blow torch or even better and Induction heat coil, and get thr nut red hot, allow it to cool to black before putting on the welded socke bar, I would if you can mage a bar to hold the hub say t over size nut weldes on a long 3/4 inch bar or 2 in 1/4in flat bar, you could drill out the flat bar and bolt it on using the wheel nuts

 

I managed to get it off last week, but haven't put the wheel nut back on. That's tonight's job!
