Detroit trutrac
Hey there jk fans. Need your help I bought a truetrac for my dana44 rear when it arrived I had a local shop here on guam change my gears front and rear. When it came time to install truetrac in rear the shop calls me and tells me the bolts don't go thru.so I asked what the solution would be. The shop calls randy and he says drill the holes bigger or get smaller bolts and put it thru the bigger hole. So they get smaller bolts they say wasn't around to see the install. I guess what I'm asking is how do I tell if the shop really installed the truetrac in my dana44 or did they jip me and say they did. Really don't wanna take diff cover off or open drain plug. How do I know it's really in there? Is there a way I can tell easily. Jack the rear up put in gear and spin tire or what else can I do to know its in there. Any advise will be awesome. Please help. Thanks in advance. Really want to know if they really installed it. Thanks again from guam671jk

5. Final Inspection.
MAINTENANCE
XXXCAUTION: TURN THE ENGINE OFF AND RAISE ALL DRIVING WHEELS OF A TRUETRAC
DIFFERENTIAL EQUIPPED AXLE WHEN SERVICING WHEELS, BRAKES, AXLES OR TIRES.
FAILURE TO OBSERVE THESE CAUTIONARY MEASURES MAY CAUSE THE VEHICLE TO MOVE
WHICH CAN RESULT IN A MISHAP WHICH CAN CAUSE PROPERTY DAMAGE, PERSONAL
INJURY, EVEN DEATH.
To verify that the TrueTrac differential is
properly installed, restrict the rotation of the
pinion shaft (by placing the gear shift lever in
park for automatic transmissions, or in reverse
for manual transmissions), and raise the axle
so that both wheels are off the ground. When
one wheel is turned by hand, the other wheel
should rotate freely* in the opposite direction.
Check in both directions.
To verify that the TrueTrac differential is
operating properly: Pull the vehicle off to the
side of the road – the left wheels on dry
pavement, the right wheels on loose gravel, dirt,
etc. – any safe place where the traction surfaces
(ground friction coefficients) are different.
As you accelerate, the wheel with the least
traction (right wheel) should spin momentarily.
The spinning wheel should then slow
down and synchronize with the opposite wheel
as the TrueTrac differential transfers power from
the low traction wheel to the high traction wheel.
CAUTION: PERFORM THIS TEST IN
AN ISOLATED AREA TO PREVENT POSSIBLE
INTERFERENCE WITH ONCOMING TRAFFIC.
