Lubegard 20404 Universal Power Steering Fluid Protectant, 4 fl. oz

I used this in my motorhome, a Workhorse W-22 model known for noisy power steering pump. I used 2 bottles since the system is so much larger than a passenger car. After a couple lock to lock turns of the steering wheel, the noise was 100% gone. I don't see why it wouldn't keep working. For the first time in years.After changing the power steering filter and fluid, there was no change, still noisy and irritating. Within minutes of pouring this stuff in, a decade long problem was fixed. Would recommend.

Lubegard products really work ! I use them in my engine oil, transmission, cooling system and power steering system. Amazing products !

With a syringe I ran 4 rounds of fresh atf fluid through the system before adding the lube guard... So with the mixture of fresh PS fluid and the LG additive I have zero squealing now... So, I don't need to buy a new power steering system as of yet... I will update if anything changes or doesn't change... GoD Speed...

I had used the lubegard universal power steering fluid before in a 90s Dodge with a Cummins. The pump always whined and was worse when the temperatures dropped below freezing despite frequent fluid changes. After using this fluid, the pump quite making the noise. Fast forward a few years and I have a bought a car that has had a rough life with very little maintenance done to it. The steering was harder than it should have been and the pump made all kinds of noise when it was cold. After cycling three quarts of steering fluid through the system, the noise was gone, however, the steering was stiff. After draining a little fluid and adding lubegard, you could go lock to lock with a finger on the steering wheel while parked.

Did not have steering pump wine, but I did have irregularity in the way the steering wheel felt / push back and in the “speed sensitive” easier to turn the slower the car that kind of thing, also I had a leak in the high pressure pipe. On my third time of adding the Lucas stop leak I sucked all the fluid out of the resivoir added this whole bottle and topped it off with some more Lucas stop leak. 700miles later and I think it did the trick, Steering feels good even, no leaks looks like and the color of the fluid in general looks good.Update: 2 years later 2020 no leak no wine steering feels perfect. This bottle saved me an $800 replacement of the high pressure steering line, Along with a little Lucas stop leak. Also pleas note I did not have any leaks in my rack n pinion.

Ok, I'm impressed. Steering was a little noisy when it was cold and chattered really bad if you turned the when just a tiny but when idling on my Kenworth t680. Revues were good so I figured I would give this a try. The result is amazing. Power steering is completely quiet now. I'm going to be adding this to my other truck too.

I purchased the cheapest new power steering pump on eBay. Despite numerous attempts to bleed air (including adapting a vacuum bleeder to the old reservoir cap) I was never able to eliminate the whine. Adding this product to the power steering fluid completed eliminated the whine in a couple of drive cycles.

had clean fluid and added the 4 oz. when i started the car i immediately noticed the pump louder than before. i figured it needed sometime to soak in but it actually got louder. drove the car for about a mile and had to come back because it was whining more than before. Drained out the fluid and added what i had been using, redline, and it went back to what it was before i added this stuff. Didn't work for me.
