The clutch plates are behind the side gears, not out in the open where you can see them. Might be tough to find a photo that shows the clutches but the schematics can be found online.
It’s a Dana Spicer Trac-Lok. If you bought a Tremor, you either have it or you got a rare factory error. Very unlikely you got two error truck
bigger question
are they tremors?
why would you buy a tremor fleet truck?
Very familiar with differentials etc.After getting stuck more than once on roadside.I hooked up to a tree and another truck locked in 4wd and see what I have. Then I pulled cover to find open differentials in 2 of my tremors. As far as fleet trucks go , i can purchase any truck I want for myself Sir
