Factory torque for axle nuts?


What is the factory torque figure for rear axle nuts?

Ok, so that is me on the end of a 300mm bar. Just as I thought.

What's the maximum?

To save starting a new thread, does someone want to let me know what the front stub axel torque setting is? Cheers :)

looks like I would need to use a pipe on the torque wrench then. I am no where near that heavy lol.

That's what I thought. :tu:

Coz most people I've come across way over-tighten them. That can end badly. :crazy:

Hi

I have a 3/4 inch tension wrench, I can do 217 ft/lb with one hand, they dont need to be overtightened as this can cause other issues.

If you are using a torque wrench it wouldn't matter if you used a 3 metre bar on it!! It will still only register the maximum torque it's designed for otherwise it will be damaged. If it's designed to do 217 lbs ft then the length of handle should be long enough one would think for any adult.

300mm = 30cm = 0.3m or 1 foot. ;)

P.s. is that you Dallas?

Yes Pete. Good to see you are still playing with VWs Pete.

I was lucky a few weeks back with the notch! that tree in next doors yard came down on the workshop. In the process of getting it demolished and re built. Notch and machinery survived but 'other toys" didn't. Lucky for insurance covering it all. Be aware that anything which blows over your fence is your proplem. Not where it came from. Slowly getting there!! See post in Chit Chat.

yeah I mean I wont even be heavy enough to reach that torque with standard 300mm length of the torque wrench. but with the trailing arm removed and a safe means of holding the stub flange in a vice, one can pull that torque fairly easy. After all everyone is stronger than their body weight. But doing it on the car will require a longer handle or a pipe.

Vlad, I sincerly hope that you have more mechanical knowledge than you suggest by using an extension bar on a torque wrench due to the fact a torque wrench 400mm long is usually only around 120 ft lbs (Warren and Brown type). By doing that will only damage it. The only way to increase the torque with a small scale torque wrench is to use a torque multiplier............. but you are surely going to tell us that you knew that and just meant you were going to put a piece of pipe on a socket/breaker bar to reduce your effort to tighten the 36mm axle nut.

I actually know what it took to undo the axle nut on Pete's buggy axle a couple of years ago, no doubt caused by someone (not Pete!) who didn't have a clue on what torque was being applied to the nut.

^ how many of your custom heavy-duty breaker-bar fittings did we break before it came undone? I think it was 2 from memory. :td:

umm? no I 2 have W&B wrenchs one micro and the big one goes to 220ft, even with 100 ft-lb bolts I do up I am putting a lot of force to get to it, typically leaning back with both arms on it.

its simple math, 1 ft-lb is 1 lb at the end of a 1 foot bar, simple! they are about 1 foot or there abouts so 217ft-lb is 98kg of force on a 1 foot bar.

my point is, I wont be able to even get to 217ft-lb with my body weight on the torque wrench, so I will need to extent it in order to get there. If I double the length I can do it by pushing with effort half of what it would be without. And you telling me I have know knowledge of this? :no:

I normally use a 2m pipe on a 3/4" drive breaker bar and jump on it to undo the nut.

Well, just to throw a spanner in the works, I use somewhere closer to 350-400 ft/lb as 217 is not enough in the real world. In the trade doing nothing but ac VW's, if I used 217, I would go broke replacing flogged out drums.

that's a good point, I always thought if it was necessary for more than the factory spec?

guess you answered my question without me even asking.

do you use a thread lube as well? wondering if a lubed thread with the factory spec would be similar to your specs, that is if you install them dry though.

I find a smear of copper-slip reduces wear&tear on the threads, and makes it easier to un-do the nuts. Also stops water from seeping into the threads and splines.... those bastards can 'rust on'.

Ok, but at what point are you just stretching the axle threads?

Always a lubed thread. I've said it before and I'll say it again, up to 700% increase in clamp force between dry and properly lubed thread and washer.
