Motor / Axle movement
Had the motor cover off doing the 48v conversion and noticed last night that when you take off fast the entire motor axle assembly seems to rotate some - if you just floor it, rotates about 1.5" or so. Pops back to center as soon as the torque is off.
Normal? |

Re: Motor / Axle movement
The whole differential is rotating. It is fastened to the leaf springs. Check the u bolt and spring purchase connections. And stop romping on it like a 13 yr old .....
Is that how you drive your truck? Electric motors deliver 100% of their hp at 0prm ~ so the start is tremendously strong & the faster it goes the less torque it has.... don't break something. |

Re: Motor / Axle movement
Yes. The more weight vs torque will try to twist the leaf springs till it creates a rolling mass. That amount will vary. The HD springs shouldn't be as bad as the stock springs.
Edit: Scotty beat me to it. |

Re: Motor / Axle movement
I drive my truck like... well like a .... crap. yeah, I see you;re point.
It's just so much fun to stomp on it now that I have it at 48V Leaf springs are almost shot so I guess that is where my rotation is coming from - is this a correct assumption? Bolts and everything else seemed goof when I checked them a few weeks ago. |

Re: Motor / Axle movement
My truck is a F-150 Crew cab XLT, Edge Evolution tuner, Airraid cold air kit and filter, catback exhaust.
After I blew the output shaft bearing seal pretty much off the transmission, I try to keep my foot off the floor now ...and put the speed limiter back on through the tuner. |

Re: Motor / Axle movement
The big difference here is that the electric motor starts off the line with 100% of its potential torque unlike the gas motors who torque rises with rpm. ( to a point) have fun but don't break sumthin!

Re: Motor / Axle movement
Scotty is right on! My truck is mostly built for it but will last a lot longer with a soft foot!

Re: Motor / Axle movement
I mainly drive the speed limit now too - or at least just stay with traffic. Repairs cost too much!
