looking for lug nut specifications for a 2005 Suburban (4x4)

It should be listed in your owners manual. I just rotated the tires on my 2000 Yukon 4x4 last weekend. The torque is 140 ft-lbs but look in your owners manual to be sure.

I looked in the manual (prior to my posting) but didn't see what I was looking for. I'll take another look. Thanks for the response.

It might be under "Specifications" or "Torque Specifications" in the glossary.

I believe the 140 ft lbs is correct on the 2500/3500...on my 1500 I torque to 120ft lbs then retorque after driving one day...never an issue...
