also they throw defender on A LOT of tires from cars to trucks with vastly different jobs and treads, the only thing i think is consistent is they tend to have a higher tread warranty and cost a lot
you just need a tech 2. my mk808 can do it as well, autel scanner. So anyone with a mid-high range tool should be able to change it. it gives you a list of tire sizes. the list actually distinctly splits between the load range D tires on duallys and load range E on trucks without dually (1 ton)...
speedometer being accurate is PCM calibration
The EBCM
The top part is the EBCM, the thing is called the EBTCM if you have traction control JL4 (i think is the RPO)
The brake lines go into the BPMV or brake pressure modulator valve which is in the middle here above that contains the motor and...
the difference forr the abs system is because theDIAMETER and THE WIDTH because the module is the same as the lowly half tons through the 1 tons (I think)
Also consider the ABS only works over 4mph when the truck can accurately determine wheel speed, under 4 it simply cannot, and under 8 its...
its a reference to the facebook group of "GMT800 with threatening auras" where everyone talks Like "HOSS I PUT A BIG BLOCK IN HER, BARB DIDNT LIKE THAT GOBBLESS"
remove cubby and you can fit more stuff in it
Find thing you want to stuff in it, then use something to keep it from falling in behind there, easy with flashiing or probably aa chunk of wood etc

Wait. I misremembered. Spinning the front shaft is only done because of the axle. It’s not driven normally , I apologize. If you had the wheels off the ground and the shafts both spun, the Tcase was engaged
np241 from a V suburban or blazer would be the WRONG drop. Which can be reclocked, but i bet there is other differences too maybe
The tcase the OP has is also always spinning the front output, so the fact they both spin is not strange
The seals are for dust not water. You can use dielectric grease on them to make them more spongy so they don’t resist removal and rejuvenate them a bit for use. I’d avoid the silicone around the housing unless you have a water getting in problem like when you splash a hose at the housing.
