DIFFERENTIAL OIL
Fill differential up to the top of the
diff cross-pins. DO NOT fill the diff
to the top of the housing.
TO ENSURE YOU HAVE THE SAME AMOUNT OF OIL FROM REBUILD TO REBUILD, DO THE FOLLOWING:
➊ Put the diff (without oil) on the scale and check the
weight (approximately 9.80g)
➋ Slowly pour oil into the diff and watch the weight. Add
1.10g of oil into the diff. The approximate weight of the diff
including oil is 10.90g.
LOW TRACTION 5 000cSt (HUDY #106450)
MEDIUM-HIGH TRACTION 8 000cSt (HUDY #106480)
SUPER-HIGH TRACTION 10 000cSt (HUDY #106510)
NOTE:
Softer oil increases rear traction, harder oil increases on-power steering.

OIL
PROPER AMOUNT OF OIL IN THE DIFFS
Use a digital scale to measure the exact amount
of oil in the diff. Remember that during operation
the diff gets hotter and the heat may allow the oil
to expand. If there is too much oil inside it may
interfere with the diff operation and damage the
internal gears.
Use HUDY Ball-Bearing Grease
