TIRED OF YOUR NOISY REAR END? THIS MAY BE THE EASIEST FIX EVER.. BONUS BAG TECHNOLOGY REVIEW. 

Thanks for the vid. I've got a howl too so will be trying this fluid out 👍

It works. I've had a few Vettes with the dreaded howl and new (correct) gear oil fixed it every time.

I have a little 97 Dakota that I use as a daily beater. The ring and pinion is worn, and noisy. But they want $400 for the gears and another 150ish for all the bearings, and seals that I'd end up replacing since I'd have it apart. I only payed 1000 for the truck so there's no chance I'm gonna put that much into it. Instead I'll try this and see if I can limp it along for a bit longer. 🤞

I'm tired of this new ticking and misfiring my Z started doing. I pray that it's just scorched plug wires and coil packs from the long tube headers, but we'll see. About to pull the transmission and build + throw a twin disc on, I'll try this in the diff too!

Taco Bell makes my rear end whine! This worked in my Exploder with 200,000 miles on it. Thanks,

Mine just rolled 61k miles, so it's time for a change. I'm going with a different brand, but they offer the same bag tech for fills. I always despised the pump and tube. You did sound deadening for the interior, but any problems with heat from the exhaust and trans tunnel? I have seen the reflective kits for heat from the trans tunnel. Any thoughts if it is a good option if I'm going with sound absorber also?

Mark, This video was perfect timing for me. I had a very strange noise coming from the rear end of my automatic. I used this product and all the noise is completely gone! By the way, one of the bullet points on the back of the bag actual states Friction Modifier. So we are good! Tip: I used a short clear hose to help feed the gear oil into the rear diff.

I put the heavy weight amsoil in my c5 6 speed. It really knocked down the whine a lot. On a side note, I looked at 6 different manual c5’s from 38k to 115k miles when I bought mine and they all had some form of whine in them.

“Doo-Doo addictive” I’m dead💀 😂

I wonder if Slip Differential Additive is the same as Friction Modifier Additive? Were the flex bags really helpful adding in this tight area?

I'm wondering if this will work for mine. I notice a noise in the rear at highway speeds but stops when the throttle is released.

75W “140W”. 140 don’t forget the friction modifier if it’s a LSD or Posi-traction

What about shifting? Mt transmission? Is Harder?

My Mustang GT is driving me nuts I’m trying this oil tomorrow!

C5 diff is so much easier to refill than C6

let us knw ,thx

Pull the tape off of that poster ¿`_

The stink is sulfur
