GM transfer case pump rub/leak problem - best fix?

[SSWaters]

So my tahoe has fallen victim to the infamous pump rub at 120K miles. Looking at this;
http://www.merchant-automotive.com/tech/tcp.pdf
or the plate from Kennedy Automotive; http://www.kennedydiesel.com/detail.cfm?ID=511 but feel the plate is kind'a like putting the same issue back in, wouldn't it just cut thru it eventually also?
What about tapping a higher fill plug and running thicker oil in the case and doing away with the pump stuff all together?
Gon'na weld/beef up the area (look for big fire at my house, it's magnesium) or buy a new case back half.
Just love how Chevy stands behind there latent defects, should have kept my old blazer.
Hey CHEVY, you're losing customers because you want fix known problems (designed in defects) in your vehicles, and they barely make it to pay off without breaking down.
So far they haven't fixed but is a known issues in there trucks;
Pump Rub holes ($tealerships really screw unknowing customers with this)
Steering Shafts
Duramax Injectors
Speedometers sticking (got the notice on this 40K past there fix window)
Auto 4wd shift problems (go back to a lever you idiots, it don't break)
Power Steering pumps moaning and can't keep up
10 bolts burning up
IFS seals always leaking
Water leaks
Castec Heads (search this and coolant loss - bring the grief)

Friend has a tranny shop, says he can't walk to the other side without tripping over all the allison trannys.
My brother in law has a duramax he tows with, told him he'd go thru the transfer case first but I beat him, lucky me.
I'll never buy another chevy that was built after 1989!

as far as those two products go either will help solve the problem after you weld the hole up. the second product is similiar to the factory but much thicker and stronger material. probably cheaper than the first one? either should last a very long time. i would advise against anything other than autotrak II in a magnesium cast gm t-case. plenty of people will say auto tranny fluid is ok too.

I'll just add that I'd be willing to bet that the fuel gauge in 2 out of 3 90's to 2000's gm vehicles doesn't work either, as well as at least one of the drl's. Just had to chime in.

Hell if you can get a front wheel bearing to last in a DMax, you should be rewarded by GM.
