(
2) - Add 4 ozs. (118 ml) of Limited-Slip differential lubricant
additive when changing fluid.
(
3) - For vehicles operating under heavy-duty towing conditions,
use SAE 75W-140 Synthetic lube.
NOTE: Before using SAE 75W-140 Synthetic the old fluid must
be DRAINED and FLUSHED with clean mineral based axle
lubricant. Then refill with new synthetic lube.
(
4) - Use low pressure grease gun to prevent seal damage.
(
5) - Fill until lubricant squeezes out from the base of seals.
(
6) - Fill ball joint until seal starts to swell.
