What 650+ rwhp does to a Harrop/Eaton TrueTrac
This morning I got all 12 cap screws holding the thing together out. Still would not come apart. Tonight I got out the mini sledge and got it to pop open. Had to beat on it some more to get the axle gears out. Some time with a punch getting the other gears out. The mating surfaces of the axle gears were the worst. Galled really bad. The side gears all had some wear lines in the middle. No big chunks out of any teeth though.

Ouch! I'm running one of these with the 1LE 3.91 center section. I hope mine holds up better than yours. I drag race a manual GXP with 500+ RWHP no problems yet. I've broken a GForce 750hp axle but knock on wood my diff has been solid.Originally Posted by TooManyHobbies

Bummer! Hope the "stronger" one holds up better.
