Finally got around to greasing the front power jacks on our fifth. What a difference!
I "assumed" that the jack factory would have lubed them, but by the change in the sound when powering up and down, it sure doesn't seem like it.
And don't "assume" that the dealer will grease them in their PDI either, as they obviously didn't do mine. The paint still covered the ends of the grease zerks.
Now I can understand why there have been compaints about failing jacks. Without lubrication, and all of that weight on them, a dry screw isn't going to last long.
