Original issue was low speed vibration during times of acceleration. found multiple issue with the front drive shaft and I changed the entire unit out (my self) with a new grease-able assembly. Issue solved...

after about a month of local driving I hit the highway for an extended trip. Enter the new problem, now I have a high speed (above 70 mph) vibration that only occurs when I take my foot off of the accelerator. the problem seems to be more pronounced when heading down grade, but have noticed the vibration during flat driving conditions as well.

Thoughts??

 

Hey, did you ever figure this out? I have a 14’ with the same exact thing. Vibration when foot off the gas around 70mph. Fairly constant hum/vibration above 80/85 that stays whatever throttle or not.

Annoying the heck out of me. Would love to fix that.

Thanks
