The tsb has obviously been done on your car and not a weird question at all.

but its weird to have an hose going up to no where tied up with tie-rap
and i think the tip ( metal ) is leaking not much but it leaks
should i take out the metal tip and put something else ? to prevent leaking more

It's an overflow vent tube, supposed to be open.

It's a vent tube as there is considerable difference in temperatures due to heat generated during normal operation. Many have had issues where some diff fluid would exit this tube, causing concern and drips. The TSB was to install a longer vent tube.

Do not block it. It might cause some of the seals to wear prematurely, and will definitely cause weeping/dripping problems over time.

Has anyone come up with a fluid trap/reservoir that would attach, allow flexion and hold all fluid that may exit, along with withstand road debris?

Though I will comment on a few rearends I've seen that made me weep.

For a diff., waste of money.

Take the metal tip off and clean it up good. It is just a gravity cap to let pressure out. Often the cap will get plugged up with some sludge, and then stay open all the time. If so, it will let a little oil out when you hit a corner. The hose should be long enough that the tip is all the way up, just below the trunk sheet metal. Make sure the tip is not jammed against something, so it can't freely and that it is standing vertical, not horizontal.

Also, if the rear diff is over filled, it will make the problem worse.

No matter what, do not over engineer this issue with more stuff. All you will do is add a bunch of BS to back of your car that you do not need, probably won't work any better, and may in fact impede the pressure relief from the rear dif.

That looks like serious over kill.

The history of the differential as I have read it beginning in the summer of 2007 is

Some owners were complaining about GO 90 dripping on their garage floors.
Many were complaining about the "clunk" sound coming out of their rearends.

GM looked and found that some production differentials were being filled more than others.

The vent is there to accommodate the heating / cooling, expansion / contraction of the gear oil lubrication. If it is not vented to atmosphere, the expanding fluid will put a lot of internal pressure on the oil seals and can cause them to fail.

If the fluid level is on the high side, when the fluid expands it can reach the vent and exit the case. This results in drips on the floor and bad looking gear case.

The fix was to
Put a hose on the vent tube that allowed the fluid to expand up into the top of the gear case and reduce leakage of splash oil out the vent.

Those complaining about the gear whine and clunk were told it was "normal"

Then there started to be more complaints and some failures of the pinion shaft. There were enough complaints and actual pinion failures that GM told engineering to go look at it. They identified a manufacturing contamination problem with the seal that caused the pinion to fail and in a few cases the differential to fail. Thus the pinion recall.

Nice post rob! On my carfax it shows previous owner had the recall procedure done, that's the only reason I knew about it before this

Manuel, check your gear oil level. If gear oil comes out of the fill plug hole, it's over filled. Also check the color of the oil, if it's milky colored, water got in it. Been in a flood or deep puddles?
