can anyone tell me the best way to get these axle nuts off 98 blazer.Have broke two half inch breaker bars tried impact not moving at all

 

you can heat it up red hot. only problem is the heat can radiate to the cv boot or the bearings seal but sometimes you have no choice. ive always been able to get them off with a impact.

 

yep heat should work but be conservative and try to just heat the nut

 

If you are going to heat the nut, do not attempt it with a small little propane or map gas torch. The temperature is not high enough, nor is there enough heat flow to heat just the nut enough to break it loose in most cases. A good oxygen-acetylene or oxygen-map (oxy-map is overkill, but what we use in our shop) torch with a rose-bud tip would allow you to heat just the nut quickly enough to minimize the heat transfer through to the bearing assembly and CV shaft.

Also, it might be time to invest in a quality breaker bar. I have broken plenty in all of the time I have been wrenching, but they have all been L-cheap-O bars. Snap-On, Mac, and other quality forged bars would be of benefit to your tool collection.

 

thanks for the help finally got 1 nut off the problem i am having now is i watched so many vidios that i am not sure what to do next. I am trying to get to bottom ball joint have brakes and rotor the 3 bolts out of bearing hub the way i understood it i was to knock shaft in and the pop off bearing hub.Shaft went in some and bearing hub wont move could some one please guide me through this this has been a real pain any help would be appreciated this is a 98 ls blazer 4wd

 

To pull off hub use a slide hammer puller. Thats how I got mine off. Theres a rubber seal that really sticks that hub to the spindle. I believe you said you already removed the hub bolts so it will just pull off with axle nut removed.

 

I`ve just used a large screwdriver on the back of the hub, there`s little slots that seem like they`re made for that

 

feel lucky the shaft slid easy - 6 ton press

 

You should feel lucky All of the pressure is pushing in on the axle, right into the differential... not good, results can be disasterous to the differential. Same reason you should never beat on the axle to break it loose from the hub, until the hub is at least partially removed from the knuckle.

To loosen the axle nut: Never use an impact, you're liable to damage a CV joint and or teeth on the ring and pinion. Before you remove the rotor and caliper, stick a screwdriver through the caliper bracket and into one of the rotor vanes. Or, remove the nut while the wheel is still on the ground. Both of these methods will hold the axle securely when you loosen the nut, rather than relying on the differential.

 

To loosen axle out of hub I used a air hammer with pin punch. Isnt that what the cupped end of the axle is for? The punch seemed to fit right in.
