NAPA had this on sale for $6.99 a qt. Anyone see any issues putting this in my front and rear differentials? I know its not synthetic and no LSD additive but its GL5 and the price was right.
As others have mentioned the Ranger either has a Open Diff or an E-Locker. The button for the E-Locker is hard to miss as it sits next to the Auto Start Stop button and I believe the Tow Button as well(can't remember for sure since it has been 3 years since loosing the Ranger).
That said if you are an Avid OffRoader, then it is nice to have the E-Locker as it will help you get through different terrain safely.
