Rear axel twist

[Cainon]

I jack up the rear end on my 85 f350 2 wheel drive dually put it in drive and reverse and I've noticed that my rear axle twist with each motion non understand there should be a little bit of play but the reason I jack the rear end up to begin with was because I was hear noise when first going into gear. My leaf springs twist with the motion as well. What can cause this

Find a helper to locate the source of the noise.

They normally twist when it's on the ground and you are taking off or stopping. But up in the air there should be no resistance to the wheels turning, so it should not twist very much up in the air like that. I suspect your rear brakes are dragging. Very common problem on these trucks. Main culprit is frozen parking brake cables. 2nd main culprit is frozen rear wheel cylinders.

Turn the wheels and see how much drag is on them when it's up in the air.

Bad joint? Or going

If there's any play in it, then yes it's going or already bad. Otherwise, it's just from overgreasing the u-joint.

I have nothing to add.

Also today she started driving different. Struggling. Now I did just fill up. Put some Howes in the tanks. Will recheck the injectors I just installed a few months back. Cheap eBay injectors. Hoping bad gas. But she is struggling.

Hoping bad gas.

Hoping no gas. Only diesel.
