Genuine Ford Fluid XL-3 Friction Modifier Additive - 4 oz.

WOW THIS WORKS GREAT FOR SURE...

I have a 2000 ford E350 ambulance with a 7.3 powerstroke diesel engine. 3 yrs ago I had to have the rear differential clutch pack replaced. I think he replaced the gears as well. He told me it will chatter a bit but would go away. It did chatter a bit but didn't go away. Recently it has gotten worse so I ordered 2x4oz. bottles of this stuff. It came in 2 separate boxes. I did order them alone due to other reviewers' warning about the smell and they weren't kidding. I also ordered a.big fluid syringe to "inject" it into the pumpkin. I have a prosthetic leg and some back issues due to a disc replacement surgery. This makes it hard for me to get under the truck so I took it to my friends shop. He had one of his young guys do the job for me. I won't lie, I also didn't want to touch the stuff. It stinks. Bad. The whole garage smelled of the stuff even still packed in the boxes. I put it in the side compartment of my van to bring it to the shop. I felt bad, the guy got it all over his hands and i.know it's going to be hard to get off. I hope he is allowed to sleep in the house tonight! Anyway by the time I got home the chatter seems to be.gone. I will have to do some serious sharp turns and reversing on an incline to know for sure, but it already is better doing normal driving with normal turns. I put 8 oz. In because that is what I saw as a recommendation for my differential. Anyway it's good stuff but it stinks. I left the syringe and boxes and empty bottles for him to dispose of!!

Wow!! It works. I rebuilt a 98 Cherokee with a 8.25 Chrysler rear end. I replaced the true track, with a new Auburn limited slip differential. I Set my tolerances and Lash, everything was good to go. The rear end howls at highway speeds, and over several thousand miles I felt it was getting worse. I did have correct lubricants, and a limited slip additive. I tried this Ford stuff, and I have to say I am amazed!! Within a matter of 30 miles, the howl sounds so much better. I won’t lie, it’s still a bit noisy, but with the gearing, differential, tires, and all the stuff you do to a 4x4 some noise is to be expected. However, it is so much quieter, I really feel it is much improved. I heard a lot of chatter about the smell of the product. Yeah, it’s there, but it’s really not near the deterrent to not use this product. and, you’ll have to admit, a rear end with over 260,000 miles on it probably doesn’t smell the best to start with!!That being said, great product, I would definitely use it again and recommend it.

Bad smell but it works

This stuff is amazing. I will purchase again and use it for any transaxle - slip extender... Silent transaxle.

Worked for what it is used for

Excellent

Just as described thank you for your time

Fantastic product. Stopped my slipping transmission

Good. But 10$ at the dealership

It does exactly what it’s intended and it’s genuine ford motor company and I used it on my F-150. Beware though it reeks. It smells like 10 year old burnt gear oil from a final drive condensed into a tiny bottle. Open a door before you open the bottle

My local differential shop that has been in business for many years use it on all differentials that require a friction modifier.. it's less expensive as most and does the same job.. bonus!
