I have done a half hanger flip and removed the overload spring. Now when I put my truck in forward gear and give it gas the front of the rear end tilts up and if I put in in reverse it tilts down. Is this normal with the overload spring removed ? Or is it something I need to look into ? Do I need to put it back ?Or is it a completely different issue ?

Thanks

 

How far does it move (tilt up)?

 

This is referred to as axle wrap and it's bad news. Excessive amounts result in busted u-joints, poor traction etc.

 

The axle should not be rotating. Check for tightness of the U-bolt nuts... you did tighten them down equally and torque them to spec, right?

Consider adding axle wrap bars if it is still happening.

 

It Moves quite a bit. I did tighten them but I didn't know what the specs was if anyone knows let me know and I will check them.

 

Spec, TIGHT!

 

Could my drive shaft be too long now ? What is the best way to measure it? I have a AOD transmission and a Dana rear end.

 

The transmission yoke should have about an inch of play to slide in and out. I don't think your DS is causing the axle wrap though.

 

I am unsure if it is causing it or not but I did pull the driveshaft and I only had 1/2" of play. Do you think that may be the cause ? Even if it isn't the cause it seems I should figure out a way to get another half inch. Has anyone that has removed the overload had this issue ?
Thanks again guys I appreciate your time and suggestions

 

How much play is there sitting on the bump stops? If you can go through the full suspension range with about a half inch I think your ok.


I still fail to see how the DS with 1/2" play right now can cause axle wrap? It would seem much more likely to be prone to axle wrap with out the over load spring as you only have I believe 4 regular leafs left, then the axle perch is very short on top of that.
