This temporarily worked after the gasket sealer dried but the axle had too much wear from salt, water and dirt that the grease could not fix the existing damage. If the axle was only leaking grease, this could have been effective.
it's not such a great idea... Not alone anyways... You want a grease that is designed for heavy wear and high speeds. (I'm not sure if marine grease is designed for that as submerged components will dissipate heat through the water)
I used just some synthetic grease that goes inside a grease gun. You can use the dorman stuff but it's pretty expensive; you'd generally use it when rebuilding axles instead of adding more to it. Not sure what each auto manufacturer uses for their axles.
Electric tape won't help hold the grease back. I'd recommend cleaning the boot with some degreaser and applying RTV or some sort or gasket maker that is not affected by oil. You could also spray some sort of plastic spray like plastidip on the hole but it'll be much less effective and may only be a temporary fix. Allow the rtv to dry for a couple of hours before driving and you should have no more leaking.
If its not making any noise then yes this will work and the axle will last probably forever. But if it’s already making noises then its only a matter of time.
@@MrItsthething I have yet to put new grease in the CV boot and I've kept driving the car this whole time. About 2 weeks ago the clunking noise went away. I've put about 500 miles on the car and the sound hasn't come back yet. Any idea why that would happen?
I live in Minnesota and my 2012 ML350 with 81,000 miles makes a clunking noise when I make a hard right or left turn. Have shown to the dealer and independent mechanic and they all said there is nothing wrong with axle, shaft or the rubber is not punctured. The noise comes only during the harsh winter and not in warm or summer weather. At this point of time I am thinking greasing needs to be done as per another video that I came across. Any idea of what grease or how much grease is needed for the AWD 4Matic vehicle? Not sure if there are 2 or 4 joints. Also, rough labor cost or how many hours it would take to do this please? Video - th-cam.com/video/XFLaCo9Pbv8/w-d-xo.html
Few things. I've never seen or worked on anything Mercedes or German. The sound in the video doesn't sound like an axle issue. My guess would most likely be the sway bar links or sway bar bushings. Could also be the worn out compliance/ control arm bushings. Axle issues would be a whirring noise or a mechanical clicking noise when driving in full steering lock circle which doesn't sound like what was described in the video. You're most likely hearing the noise because the bushing become firmer in the winter time due to the rubber compound getting hard and not hearing issues in the summer since it is softer. I would not advise messing with the axles. Check over anything suspension related- most likely sway bar bushings since they're rubber or worn out sway bar links (these could be regressed it they have a fitting on them). The control arm bushings are also rubber and can crack or wear out which creates noise similar to that video. If you're hearing this noise only at hard turns, your strut top hats may be wore out and need to be replaced.
90% of the time...no grease seen = axles in tip top condition however, use this method on your ball joints and tie rods. then spray all the rubber stuff with 303 and let it soak overnight. Should fix your issue
@@AleksUsovich is this what you were hoping at the wheel end that the grease would make its way the the bearing? I noticed you pieced the boot quite far from the bearing section. Would the the constant rotational velocity work the grease into the bearing area? Also will rtv rubber and rtv silicone do the same job for sealing the boot
Why not just release the clamp a bit to fit in the grease gun fitting instead of puncturing the boot...? Good luck getting decent rtv adhesion on an old cv boot.
Most axle clamps are one time use clamps that require a special tool to tighten. Removing that and adding a hose clamp makes the axle out of balance and produces vibrations during driving. If the boot is sufficiently clean the RTV sticks to it without any problems
Most likely not. If you're hearing a sound that means things haven't been lubricated and more than likely wore down without lubrication. This works best for boots that have a tear in them or a lose clamp.
You can use a regular hose clamp if you have a loose clamp; just cut that one off and fill with any grease (synthetic grease is better) and put a hose clamp that tightens with a screwdriver on it. Could help alleviate the issue.
@@AleksUsovich ok I appreciate it. First time I've ever worked on any CV joint, driveshaft or wheel bearing type problems. So I had no idea where to even start digging around until I started looking at TH-cam and finding videos like yours. Unless my sound is totally something different on top of the leaking boot. Who knows. the sound first came out as like a whistle or recorder instrument type sound then turn into a scraping a grinding followed by a kind of a moaning and groaning which it is now and it's especially noticeable when I'm decelerating fast from higher speeds. But I know it's not the brakes cuz I just changed those. somebody said maybe the bearing on top of the rack and pinion maybe. or I thought a wheel bearing. tough stuff to me but I'm going to try what you said to try first. Lastly somebody told me WD-40 works in a pinch to use that as Grease for inside the boot? Is that true
Now you are only poking a small hole in the boot. Use a lot of RTV on it make sure it’s clean as well. This can work I have only done it once I wouldn’t do it again. If CV axles are old and noisy and your gonna change them soon id do this to get me by so it’ll get quiet and help em out. If you daily drive, that hole poked, as you turn and the boot stretches it may possibly tear itself from that tiny hole. I wouldn’t do this on new axles especially.
The axles on the vehicle had over 250,000 miles on them and had nothing to lose so I regreased them. It didn't change the noises since the bearings were all wore out from the dirt and other debris. May work for someone with older axles that are hard to get to or with non removable clamps.
@@AleksUsovich yea. That’s good they lasted that many miles. Lucky you. The boots would tear then the inside get dirty leading to axle going bad. Good on you. Only ways boots tear is if something hits them. I don’t see any other way! Once getting super old I’d do what you did there and grease them. Some new CV axles come so pre greased that the grease leaks out of the boot all over everything it can get kinda annoying. I bought NAPA axles that leaked grease all over my spindle, brake hoses, lower ball joint. Yep.
bruh...you are way overthinking. that tiny hole wont do any damage For reference, when i was a student back in 2014, the CV boot on my suzuki swift was basically in 2 pieces and no grease at all. I had neither money nor tools to fix it. All i did was fill it with wheel bearing grease and literally pack the whole thing with rtv. The noise was pretty much gone after i did that. I drove the car for another 2 years that way. Of course, it would shoot grease out sometimes but id just inject some at every oil change... Eventually fixed it with a split boot and correct grease and sold the car to a friend... It still runs perfectly to this day with that same axle and boot
@@DesiAnanth what. The tiny hole you make in the boot if it isn’t sealed up well with gasket maker it would eventually fail and your boot would tear more as leak grease everywhere and cause a stupid ass mess.
@@JacksonGuitarsPlayer03honestly it depends on experience, as you can clearly tell there’s people who haven’t experienced what you have. Just cuz it happened to you doesn’t mean that’s everybody’s situation. I never go based off what people say, I just take care of it differently lol Example I wanted a truck, everybody telling me Ford sucks, I wanted a Silverado, fords running strong af and I see other silverados breaking down, not saying ford is better but just trying to explain how suaitions can be different for everybody
Hi, this temporarily worked after the gasket sealer dried but the axle had too much wear from salt, water and dirt that the grease could not fix the existing damage. If the axle was only leaking grease, this may have been effective.
Can the driver's side axle be done in the same way? What type of glue is needed?
Thank you Sr, it works !
Perfect, thx😊
genius
Since doing this has there been any issues and the CV joint is alot better?

Ok thanks
Wondering if you use a Marine grade grease it won't wash out as easy.
That's a great idea!
it's not such a great idea... Not alone anyways... You want a grease that is designed for heavy wear and high speeds. (I'm not sure if marine grease is designed for that as submerged components will dissipate heat through the water)
Hi sir may I ask what kind of CV grease do u use to add??? May I use "DORMAN CV BOOT GREASE" $11/bag is it good and same on honda and toyota, thanks
I used just some synthetic grease that goes inside a grease gun. You can use the dorman stuff but it's pretty expensive; you'd generally use it when rebuilding axles instead of adding more to it. Not sure what each auto manufacturer uses for their axles.
@Aleksandr Usovich thank you , you have a nice day
i have a slightly bigger hole in my mine and used electrical tape but its still leaking grease slowly..
Electric tape won't help hold the grease back. I'd recommend cleaning the boot with some degreaser and applying RTV or some sort or gasket maker that is not affected by oil. You could also spray some sort of plastic spray like plastidip on the hole but it'll be much less effective and may only be a temporary fix. Allow the rtv to dry for a couple of hours before driving and you should have no more leaking.
I'd use hockey tape, electrical tape is PVC and lets go faster.
Clean the area of the year and apply super glue and hold the rubber together tightly for 1 mins or so. It works if the tear is not huge
Can you do this as maintenance to prevent it from breaking
If its not making any noise then yes this will work and the axle will last probably forever. But if it’s already making noises then its only a matter of time.
I'll try this method on my car and see if it helps. I have a clunking noise on acceleration.
Just make sure to let the sealer dry fully before driving or you may have issues
@@AleksUsovich absolutely! I have the ability to let it dry for a whole day. I appreciate the advice. I'll let you know how it turns out.
That won't fix it. A clunking noise means metal has been worn away, and no amount of grease will replace that.
@@MrItsthething I have yet to put new grease in the CV boot and I've kept driving the car this whole time. About 2 weeks ago the clunking noise went away. I've put about 500 miles on the car and the sound hasn't come back yet. Any idea why that would happen?
@@bigilworth just a guess from a newbie, could it have been that the grease worked itself around in the boot?

Can this be done at the knuckle joint end of the CV boot?
I'm sure it could be but you've have to make sure that grease actually gets into the joint

Most likely not. If you're hearing a sound that means things haven't been lubricated and more than likely wore down without lubrication. This works best for boots that have a tear in them or a lose clamp.
Mine gets louder as it gets warmer no noise at first. It's leaking all over the place cuz of a loose clamp the bigger clamp you can spin around
You can use a regular hose clamp if you have a loose clamp; just cut that one off and fill with any grease (synthetic grease is better) and put a hose clamp that tightens with a screwdriver on it. Could help alleviate the issue.

No do not use WD40 as grease inside the boot. You will remove the actual grease from inside the boot and cause long term damage.
I need the name of the grease to use.
Any grease will do
@@AleksUsovich No it won’t you need No.2 cv axle grease. High temp and high pressure. Cv grease only. Also same color!
Now you are only poking a small hole in the boot. Use a lot of RTV on it make sure it’s clean as well. This can work I have only done it once I wouldn’t do it again.

I used regular synthetic grease by Mobil. Can also use some marine or wheel bearing grease as well
Was this effective ??

You have broken the boot 😑😑
If you watch until the end of the video you would have seen that I fill the hole that I made with rtv gasket sealer.
@@AleksUsovich no issues yet?
