#17 of 46 Oversize tires by dclawman4155

Oct 08, 2007 (8:13 pm)

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.

Thanks for the input, 1 offroader. My 2500 is a 6.0 liter.

#20 of 46 Wheel Axle Nut by agdawg

Oct 10, 2007 (6:52 am)

I just replaced the wheel hub assembly on my 2005 Crew Cab. The torque specs said to torque to 177 ft/pds. My torque wrench went to 150 ft pds. My question is it ok to kind of guess where the needle would be at 177 and to keep turning the torque wrench till you feel its at 177. The truck drove great to work this morning but I feel I need to go buy a new torque wrench that goes up to 177 and readjust the nut.

That would be a good investment for future use as well unless you have a "real good feel" of what 177 ft lbs is. You don't have to buy a $500 1/2" Snap On torque wrench as a cheap one from Checkers or Sears would do.

Are there any known options that I might have to get better traction from my factory rear end. My truck has very low milage.

#25 of 46 2008 SILVERADO REAREND NOISE by netcrasher96

Dec 09, 2008 (9:42 am)

I have a 2008 Silverado 2wd. 3000 miles. When I make a slow speed turn (Left or right) I get a pop,pop,pop noise from the rear end. I had the truck serviced at the dealer. They told me the factory used the wrong rearend fluid. My dealer serviced the rear end with the correct fluid but I am still getting the noise. Also the front tires are cupping real bad. This is a point A-B vehicle. no hauling or abuse. anyone have any ideas?

Also the front tires are cupping real bad.
 
That could be due to alignment, improper balancing, or just plain crappy General tires.
 
The popping noise on turns could be a loose crossmember as obviously it's not the fluid in your rear end.
