I bought a new '90 2500 LD 2wd 5.7 6 lug axle 7200 GVWR with the 9.5" semi floater long bed 4.10 gears. Towed doubles with it for 8 years. TB engine with a whoppin' 215 hp/300 torque. It had 235k miles and gave it to my 17 year old grand son who ran it up to 247k miles and sold to a 16 year old teen in his town. The last my GS heard of the old truck it had 310k miles and the 9.5" was the same....just gear oil changes.
I see one of the Dmax/drag race teams used the 9.5" axle in their std cab short bed drag truck. Tough axle.
Yeah never an issue with these axles. I ran the repair shop for a landscaping firm when I was in high school. We had several squarebodys (back then they were just "pickups", lol) from 77-86, this was in the late 80s early 90s.
And a couple 67-72 trucks kicking around. Don't recall ever working on any of the 14 bolt axles full or semi.
But your '90?
I maintain, to this day, that the most reliable pickups ever made are/were GMT400s. Have similar stories of absolutely driving the wheels off some. Just like obs Fords with 5.8s in them.
