Hello
I use a 2001 ZR2 Blazer as a runabout, daily driver, touring vehicle, off-highway, "everything" rig - and as such my efficiency modifications need to be as transparent as possible, for example I use the roof rack 2-3x a month so it stays on the vehicle.
Specifically in this thread I'm curious about manual lockout hubs for the S10/4x4 drivetrain. Anyone ever see such a beast? The existing 4x4 system uses fixed spindles which always turn the differential and a vacuum operated disconnect on the passenger side axle shaft. This prevents the front driveline spinning, which surely is good - but the diff itself is constantly turning, as well as the CV's etc.
I recall on my 120-horsepower Trooper when I neglected to unlock the hubs after drive in 4x4, the truck was very noticeably sluggish - comparable to driving with the A/C on in a 4cyl car - and would immediately become more "lively" with the hubs unlocked.
So... S10 lockout hubs... ever hear of 'em? Thanks!
