Regarding GM marketing...I haven't seen a decent TV ad yet for the new Silverado. The fact that it outsells the Tundra 6:1 (or whatever) is a bloody miracle, given the poor quality of GM advertising. That Toyota has gone to extraordinary lengths to create elaborate (and bizarre) ads for the Tundra should tell the competition it means business, even if the ads make little sense (to me at least).
 
Why can't GM come up with a decent ad??? Hey Chevy, for a fee I'll help you put together an ad that will sell a bundle of Silverados to other guys like me who use trucks.
 
Feel free to contact me. I'm not cheap, but I'm good!

They spent all their ad dollars on those Transformers...

That would depend on who's doing the rebuilding. You or a shop.

as far as what parts need to be replaced on the rebuild. I assumed a total rebuild parts and labor in the $1200 range. Course you may find it cheaper to go to a junk yard for the parts as some shops will do that upon request.

thank you, I was just feeling like I was being overcharged with an estimate.

Oversize tires by dclawman4155

I'm considering a 6" lift on my 2500. To fill the wheel wells, I'd like to go to 35's on 20" rims. Will the extra weight (100+ lbs.) versus stock (62 lbs.) cause far too much stress on the front axle stubs? I can't find outer axles (4340 steel) for the 9.25 IFS anywhere. I certainly don't want to snap an axle.
 
Any input?

The weight of the wheel/tire combo isn't the major issue, it is the larger diam., or actually the larger radius, that increases the torque stress on the front short shafts. When you increase tire/wheel size you are turning the axles against a larger radius, which increases the torque on the axles. I think you'll probably be OK since it is a 2500 with the heavier front end components, but still, you will need to be a little more careful about applying power. I would be especially careful if you have a diesel, which is a very torquy engine.
 
You could get special axle shafts custom made at considerable expense, but then the ring & pinion would be the weak links, or maybe something else.
 
That is the problem with major mods - you do a change, then you need to beef up something else, which leads to beefing up something else. It can be a never-ending process.
