Okay i have a 91 chevy truck 2wd with the five lug wheels and 3.08 gears. I believe the rear is starting to go out and am pretty much a tight wad and don't want to spend the money to have the rear end rebuilt (never done it myself and don't know where to start!) I have access to a couple junk yards with TONS of these trucks so parts are plentiful. I am wanting to upgrade to a 3.73 gear. Does anybody know if chevy made a 5 lug rear end with 373 that is a bolt up for these trucks? Thanks for your input. I do know the codes to look for in the glove box for the rear-end ID. But don't know if chevy even made what i am looking for! thanks again.

My 03 had 3.73 gearing- but when I went to replace it the junk yard wanted
over 1000. for it as the plow trucks guys were always looking for them. The
3.40 gear rear was 400.

My old '94 W/T1500 had the 3.73:1 gears, stock. Bought the truck new in SLC, UT, so the high elevation may have played a part. Was a V6 / automatic 2WD RCLB.
All the local Pick-N-Pull type salvage yards get $150 for those axles, and don't care what ratio or year.
Why is yours failing? Been overloading it? If so, get a 3/4-ton axle instead. Not 1-ton, as the spring centers are closer.
Also, there's no reason to avoid the 4WD axles.

To my understanding all the 3/4 ton axles were 6 and 8 lug? Is that true?
