Let me start with the "coil vs Leaf " spring debate. As I stated in a previous post, there are advantages and disadvantages to both designs according to our engineers. We use coils in our HD filters for example. Mann is currently running advertising touting the benefits of leafs, saying they help to position the cartridge in the can, they use both.
they both work.
Now, on to the problem filter. After close inspection, the leaf spring was fatigued and was the cause of the rattling. That said, we found a dent on the bottom of the filter indicating it had been dropped at some point in time. It may have happened at the store or who knows where. Difficult to see as it is under the sure grip. The cartridge in the Ultra is heavy and dropping it could cause the spring fatigue.
Mullick-
I would like to send you a case of Ultra filters in whatever part number you want for you trouble and help in getting this resolved. Just email me at [email protected] and I will ship them asap.
Sorry for the trouble.
Jay, very well done.
This is why I always take the filter from the box and inspect it. But, being FU's are sealed you won't know if it is damaged until after purchasing it. If a consumer finds a damaged FU filter after opening it what are they to do?
I would open the box, with the understanding that I will buy it if the filter does not show any signs of damage.
But that's just me.
