Comments about Royal Purple Gear Oil Syn 75W140:
AWESOME PRODUCT.......I was hearing and feeling a grinding, knocking, and ratcheting sound from my rear differential on my recently purchased 2000 Dodge Ram 1500 Quadcab 2WD. The person I bought it from told me it would be needing a new rear end very soon. So..... I drained and cleaned the 12 year old differential and refilled it with Royal Purple 75W140 Synthetic Gear Oil. The noise dissapeared and the truck became as smooth as silk. Needless to say I am a Very Satified Customer.
Bottom Line Yes, I would recommend this to a friend

Comments about Royal Purple Gear Oil Syn 75W140:
The differential in my 2002 Dodge Viper was making a whining noise when turning after warming up. I swapped out the factory lube with the Royal Purple, and the noise is gone. Very happy with the results for the money!

Comments about Royal Purple Gear Oil Syn 75W140:
What a great product!!! I replaced the gear oil in my front and rear differentials on my F250 Superduty. Before I used Royal Purple the rear axle started whining above 60mph on the highway, and the front axle was noisy in 4wd, AFTER using Royal Purple the noise completely went away in both drive axles. Also when driving at 55mph my tach would read 2200RPM before using R.P. and now after I changed it reads 1800RPM, this synthetic is obviously much more "slippery" the the factory slop they put in there! I also have ordered Royal Purple 5w30 motor oil for my Superduty as well and I am sure I will not be disappointed!
Pros
- Works Great
- Worth the extra money
Cons

I used this in my wife's 06' Jeep Grand Cherokee differential and wow what a difference. The jeep feels smoother, rides better,and almost feels new. I would use this product again and would highly recommend it.
Also, I never rate products. I was just very impressed with the results.

Comments about Royal Purple Gear Oil Syn 75W140:
Great product. Running it in my front & rear locking differentials. Rear is limited slip with a locker - no binding at all on sharp turns. Do not use any limited slip additive unless you try it without first you absolutely need it. This stuff is slippery and works great!
Pros
- Contains proper additive
- Cost less then GM product
Cons

Comments about Royal Purple Gear Oil Syn 75W140:
To fill, use a long plastic or rubber hose that extends from the transfer case to outside of the area of your vehicle. You can't tip the bottle enough to empty oil without using a tube.

Q:
My 2005 Ford Explorer takes 80w-90 in the front axle and 75w-140 synthetic in the rear axle. Why is that?Asked on 1/27/2013 by Todd from New Castle, Pa.1 answer
CUSTOMER CARE
A:
With reference to your inquiry on the Royal Purple Gear Oil Syn 75W140 - Part No. 01301, a rear differential transmits power from the transmission or transfer case to the wheels. A transfer case is used on all-wheel drive and four-wheel-drive vehicles to split the power between a front and a rear differential. The construction and maintenance of front differentials mirror that of the rear on the same vehicle. Most differentials call for SAE 75w-90 / 80w-90 gear oil, however some heavy-duty and limited-slip differentials need SAE 75w-140 gear oil. I would recommend that you follow the recommendations of 2005 Ford Explorer manual. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.Answered on 1/29/2013 by John the Car-Doc from AAP
