Towing!! Removing axle on Heavy duty truck!!

Recommended Posts

When we can't remove the drive shaft.. Do we need to remove one two or all the axles? some people said only one it's fine (I don't think so) some says remove all of them and some say remove only two in diagonal. Please can have some explanation!


Thanks,

Félix

There is no cookie cutter one size fits all answer. You really need to be familiar with the axle manufacturer recommendations for the axle setup. Following manufacturer recommendations to the letter will keep you out of small claims court.

There are tons of different final drive systems out there. And each one has a specific procedure to dis-engage it properly. with that said I had found over the years that On most single screws ( 1 drive axle ) As long as the diff lock is dis-engaged,( if equipped ) Pulling one axle will do. On certain twin screws, one from the first axle does the trick as long as the power divider is disengaged. If time and space allows I used to pop one axle out from the first drive, then move the casualty a few feet then look to see if the drive shaft turned at all. ( a quick mark with a grease pen or piece of tape on the drive shaft makes it easy to see if it rotated at all ). If it did not move then I was on the road, If it did then I would pull a rear shaft out as well. I cant say for certain that my system is 100% the right way, but it worked for me the very few times I had no choice but to pop axles. I was never a fan of pulling axle shafts and I can probably count on one hand all the times I ever had to resort to it throughout my career. I am most certainly a pull the drive shaft guy. And knowing this, i made sure to buy all the right tools ( proper, quality sockets, good impact as well as breaker bars and ratchets and a good u-joint press tool for those particular types out there ) to make removing drive shafts as painless as possible. Just be careful playing with all the different setups out there, especially with todays fancy stuff.   


There are Tow Truck Drivers, Then There is Towing and Recovery operators...... Which one are you??🤨

Thanks! I’m not a special fan of poping out axles too but when you have said to be sure to have all the right tools to remove drive shaft have you special tools that you use ? Other than ratchet and socket and braker bar.. tools that are very good to know to help.

thank you 


Thanks,

A good high quality cordless impact tool is a big one to have. Also, with the right socket it will help with caging brakes too. A can of brake clean and a wire brush is good to have for cleaning the grease and crud off of the bolt heads to make sure you get your socket on those bolts with a good bite. and a u-joint press tool for the pressed -in style u-joints is a must have. there are ways to pop them apart with out the tool but i am not going to mention how because I feel it is very dangerous. A good u-joint press is a lil expensive but worth its weight in gold in my opinion. Of course a good pry bar and hammer is a must have as well. If you are new to this then I also suggest contacting some sort of training academy or at the very least stopping in at a local truck shop and talking with someone who disassembles this stuff regularly. they will have some tricks and suggestions to help you out there. Not only can you cause alot of expensive damage if you dont know what your doing, you can get badly hurt as well.
