VOLVO 780 OVERWEIGHT STEER HELP!!

No, just move the 5th wheel back further. Moving the trailer kingpin back takes more weight off the steer axle.

 

That WS is also carrying more total of the engines weight straddling over the steer like that.

 

Well that is my original train of thought. That would make sense.


So what is the purpose of the setback front axle.


It rides like crap because you are sitting on the front axle and feel every bump and steering correction. Kinda like driving vans.

 

Setback axle generally puts more weight on the steer axle. In applications where trucks are paid by weight you want to maximize the axle weights. Depending on the truck setup it might not be possible to get max legal weight with a set forward long hood.

Also gives a better turning radius.

 

Even for for dry van running 48 ?, Volvo or cascadia's dont come with set forward axles ? I couldn't find comparison on those two brands from 2014 and up to 2016 .nothing on net search shows how to tell what u buying till you ask I guess hope salesman know it.

 

I can only speak for what I know and I've never spent any time around highway trucks. All heavy duty vocational spec stuff so I honestly can't give an accurate answer for why highway tractors have them.

 

No, they don't. There are very few set forward trucks anymore. 389, 579SFFA, which are uncommon, W900, 9900 International, and that's about it except for some vocational trucks.

 

Yea got call from premium truck sales dallas location they all over the country I asked him he said I'm gona have to ask my engineers ? And get back to you when did he said 99% come with setback axles one should have round front bumper and the other kind strigh from front . Then I tried searching bumper with setback axles for cascadia and volvo and some online part shops specify set back for sale and some charts showing bumpers from different yers but still I couldn't figure it out.
So I guess that's how it is .

 

They did have some set farward but then prices increased by almost 10 k and some 2016 with around 380 k miles price increased to 80 k 12 -14 k more then others .

 

This is why Volvos are bad.
