Hi good fellows.
I have been taking things apart in preparation for an "out the top" engine swap. I took off the headers, intake manifold, water pump and fan, alternator,heads,fuel pump, distributor and power steering unit. Believe it or not those came off without incident. So, following the guide, I took off the right front wheel (front jacked up from the center with a 12 ton jack, 2 6 ton jack stands placed).
The axle nut won't budge. Have used 3/4 drive breaker bar with a pipe for leverage, an impact gun, various penetrating oils and propane heat.
I have an engine(a 403)all rebuilt with all the necessaries as I've read about, but if I can't get the right axle out....I can't remove the old engine.
I keep looking at it to see if it's reverse thread, but I don't think so.
Anyone have a suggestion?
I sure would be grateful

We used a 3/4" drive on a breaker bar with a 10' length of steel fence post for "additional leverage.". Did work. Tapping on the nut, while it is under tension also helps.

Sigmund,
The axle may have been tighten to 200 or more FT/LBS of torque. You will need at least a 3/4 in or 1 inch breaker bar at least 18 to 24 inches long and get yourself a 6 or 8 Ft piece of heavy pipe and use that as a lever. They can be tough to loosen. The impact needs to be at least a 3/4 in drive and good to 350 FT/LBS, the 1/2 inch drive won’t cut it. We have had 2 people on the end of a 6 foot pipe to break them loose.

Why does that nut have to be so tight. Doesn't it just keep the splined shaft in place?

Sir, if you are taking engine out the top, the axles can stay in. Just remove the 2 bolts in the bearing bracket. When installing have helper keep the bolt holes up, it can be a bear to turn installed. I have a 1" impact and axle nuts are no problem.

John,
You have two taper bearings with a pre-load spacer between them. To get
the bearings set up right you have to torque the wheel nut to insure the
bearings are pre-loaded correctly.

G'day Ziggy,
Haven't seen that nickname since I was a kid growing up in Hoboken!
To solve this problem I bought two of these (one for Houston and one for Sydney) on sale for $85.00 awhile back:
http://www.harborfreight.com/1-in-pistol-grip-air-impact-wrench-62355.html
I'm a tool junkie!
If you review the specs below you will see that it produces 1500 ft. lb. torque @ 90 psi
Name 1 in. Pistol Grip Air Impact Wrench
SKU 62355
Brand Central Pneumatic
Average air consumption 11 CFM @ 90 psi
Housing material Die cast aluminum
Maximum speed (rpm) 3800 RPM
Maximum Torque (ft. - lbs.) 1500 ft. lb.
Working pressure (psi) 90 PSI
Air inlet size 3/8 in.
Drive size (in.) 1 in.
Product Height 10 in.
I would suggest you Google "1 pneumatic impact wrench rental - Los Angeles."
While your emails don't have a signature that provides the model of GMC you have or where you are I went to your profile and read a
couple of messages one of which stated you went to Miguel Mendez's shop but it was gone so I figgered you were in the LA area.

Yes, but not much. Remove starter then turn engine with big screwdriver against ring gear to remove the 3 torque converter bolts and push torque converter back in tranny bout an inch. Remove the long bracket bolt and nut on the diff. 2 front mount nuts. Floor jack under diff and jack up as you lift engine. When front mount studs are clear of mount, shake it or pry forward. Stop jacking diff when it separates. I would suggest removing a coolant drain plug on each side to drain block. Big mess on the ground is better than inside the coach.

It looks like the engine has to move forward to come out. I assume that is because the transmission torque converter has to be accessed. The axle is to the front of the engine oil pan reservoir. Is that incorrect??[/quote]

Easier to remove the tin dust cover also. Remove the 2 bolts you can see then drop it down and slide toward pass side. Bolt hole on drinkers side is slotted end hole and cover will slide out without removing. Install tame way..

On the axle nut and any other stuck screw-type fastener...Lube it with ATF and carb cleaner mixture and then TIGHTEN it just enough to crack the threads loose, then loosen it to remove it.
