Dang, I replaced every single bushing on my Pathfinders suspension and steering 2 years ago with poly, I used some super sticky white brake grease, but the rear just started squeaking. My OCD has me contemplating redoing them, I'll definitely be giving this a try. Thanks for sharing!

[@chuckmaddison2924]

Many thanks, I don't think you realise the extent of how far your information reaches. I found you not because of cars but urethane. The problem is with electric skateboard's using hub motors ( direct drive) after a while you get clicks and and other noise. There are many suggestions of why. I did hit on it after washing the skin tyres but have now used silicone spray. I shall now install the Teflon and spread the word. Many thanks again.

Quite brilliant. I have a rear shock mount squeaking like crazy. I am thinking of greasing it. But adding a couple layers of greased teflon in the rubbing surfaces will be a master stroke.

[@jinxtacy]

It's interesting because I've been searching for an alternative to polyurethane for so long for this very reason but it seems like all the great stuff lubricating materials are harsh. My conclusion was cylindrical delrin sleeves with an extended stay within a urethane bush. This does look like a cool trick though. Trying to get that low durometer polyurethane that won't cause binding and squeaking. If that didn't work I figured the only real viable solutions were to either get rubber bushings and enjoy the compliance or get sphericals. Cheers for the great idea!

[@StudioVRM]

FYI - I did actually have to stand on the inner sleeve to press it into the control arm. It just looked a bit odd so that bit got edited out.

Also worth noting that manufacturers warn thar petroleum based greases destroys polyurethane bushes and should be greased with a silicone based rubber grease.

You are correct. Petroleum Grease also destroys rubber too...... I use Super-Lube...It is silicon based and has Teflon in it.......Plastic and Rubber friendly. It is also Food Grade, not that I lick my bushings before installing them. ;-)

Thanks so much for sharing this trick! Would it be helpful to install zerk fittings in addition? or would that be unnecessary?

[@StudioVRM]

I haven't found a need for it. I've gone 5-10 years without having to regrease some of these poly bushings once I got a solid layer of teflon tape between the bushing and the metal. The key seems to be to use one thin layer of teflon tape and to minimize the amount of overlap that you have in the tape. That keeps the tape from being squeezed out when you press everything together.

[@whlawson5812]

In U-tube under "Garage Fab" there is an episode about making a housing for a bush. When the hollow metal insert, for the bush, is bolted tight the insert & the bolt becomes not moveable. The hollow metal insert is slightly longer than the installed bush - such that the bush could pivot freely on it's non moveable hollow insert. 😮😮😮 Please have a look as concept should be the same when PU bushes are installed as replacement in OEM arms such as yours.

[@profiskipinternational4402]

will try this on the polyurethane disks/bushings of a sliding system in a rowing boat. marine greace seems a good idea, as we use it for lubrication of the propellershaft running through a stuffing box. In my boat I have around 47 C degrees on the bearing measured. So I think so long you have to deal with high temperatures, such grease might work well also in a car. :-)

[@bradarsenault6984]

that side of the bush is not supposed to move relative to the bore its mounted in. the ID and the metal sleeve that fits into it is where the movement and lubricant should be.

I have a question does painting or galvanizing the piston part help reduce or eliminate it from ever squeaking besides using the teflon tape?

Unfortunately not. Galvanizing slows the rust, but it doesn't seem to stop the polyurethane from sticking to it. Painting makes the sticking problem worse.

I would say that you will notice an increase in NVH (especially when you go over rough roads or potholes). If the car will be primarily driven on the street, I would recommend sticking with rubber bushings for that reason. If the car is more of a weekend car or a dual duty autox / track day car, poly bushings can be an economical way to help refresh those old bushings while improving the handling of your car under hard cornering.

Yes, I've had very good results doing this. I actually found out that one of my friends has also been doing this for some time, but he has been skipping the grease altogether and just relying on the yellow (heavy duty) Teflon tape to keep his bushings from binding. I haven't tried that one myself but he was the previous owner of a respected Honda shop in the Mid-Atlantic area so I tend to believe him.

[@musicmandz]

StudioVRM many thanks for your response 🤗

[@newfie-dean5803]

I guess this is a good strategy for sway bars with poly bushings too and you could just wrap a single layer around the bar where the each bushing slides over it. Marine grease is the same as PTFE grease, correct?

[@StudioVRM]

Yes, this trick works really well for those kinds of bushings. Most marine greases are actually petroleum based rather than PTFE based, so they can cause discoloration on poly bushings. While they will still work, most manufacturers recommend using a PTFE or silicon based grease.

[@newfie-dean5803]

Can't do it? There's no clearance for PTFE tape; it just get's pushed off when you try and assemble?

[@StudioVRM]

Try wrapping it so it goes slightly over the edge of the bushing where you press it into the arm, then apply the grease over the teflon tape. If there's any grease between the tape and the bushing, it will slide off on assembly, so make sure you get the bushing squeaky clean before you start wrapping.

[@Engineerboy100]

Prothane grease does the same thing. It has silicone in the grease that bonds to the bushing like the Teflon tape and keeps the bushings quiet for years. I've had it on my BMW M3 for over 10 years, still quiet and I just put it on the bushings Installed on my Porsche last week and they are perfectly quiet of any squeaks.

[@bayougtr]

Any truth to the “red bushings squeak, black bushings don’t”. Being that the black bushings have a higher graphite content?

[@StudioVRM]

In my experience there is no real difference between the two in terms of how much noise they make. Once the slippery coating wears / washes off, they both start to stick and squeak the same way.

[@whlawson5812]

Has anyone tried drilling & filling in a small grease nipple into such arm before fitting in greased PU bush + a layer of thin Teflon?. Then grease the arm slightly every year. Also what if the hole of PU bush comes with Teflon liner of say 0.5mm thick?.

[@StudioVRM]

The Teflon liner is a very interesting idea! As long as you can get a sheet that's thin enough that you can get it in there without it getting squeezed out, this could work really well. I know you can get 1/64" PTFE sheet for relatively cheap off of eBay. I might experiment with this the next time we do a nut and bolt on one of our cars with polyurethane bushings. I have seen people drill grease fittings into those arms for polyurethane bushings (primarily for the split kind, like the ones in this video). There's usually enough of a gap between the bushing halves that you can use a grease gun to force some lithium grease through. I haven't had much personal experience with this method though, so I'm not sure how well it works, but I have to imagine that it will do something.

How is it even possible that the Teflon doesn’t slip up when you’re sliding the metal inner part into the bushing ? I mean, is it glued down ? Swear I can’t wrap my mind around that, the hidden camera cut doesn’t help

[@StudioVRM]

Keep the bushing dry when you wrap the tape. The slightly sticky coating on the polyurethane bushings holds the tape in place. Then grease the outside of the Teflon tape so it will slide easily into the control arm. That will keep it from being squeezed out when you press it in.

[@tigoxbrata]

StudioVRM no, i totally understood that part, but what about the metal tube itself ? It’s press fitted inside the bushings, how does the Teflon not simply slip out to the opposite end you’re pushing in from

[@StudioVRM]

@@tigoxbrata Similar sort of technique, but keep the metal tube dry and lubricate the inside of the bushing. It also helps to wrap the teflon tape in a spiral and leave a bit of the material sticking over the end. That will help keep the tape from being squeezed out when you press the tube in.

[@tigoxbrata]

StudioVRM okey! Will try ! Thank you for the tip

[@StudioVRM]

@@tigoxbrata Good luck. I found it helps to keep the Teflon tape layer down to a single thin layer and press slowly. The tape doesn't have to look perfect and you don't need 100% coverage. The key is to get some of it between the poly and the metal so that it can move more smoothly than it does otherwise.

[@gdubleu]

The bush is not suppose to move, only the sleeve.

[@StudioVRM]

Yes, that is often the intent of the original design. In practice these types of round single axis bushings do work better if you allow both the sleeve and the bushing to rotate freely. You just need to make sure that there aren't any sharp edges or burrs on the control arm that could tear the bushing up when it turns.

@@StudioVRM True sometimes you can grind a little off the arm and use a polished spacer to completely protect the bushing.

[@StudioVRM]

You know it. Fronts for a 4th/5th gen.

[@fuzzedoutsounds]

You realise the outer of that bush is not supposed to be greased or move at all right? Its supposed to stay fixed in the arm and the inner crush tube bends and flexes with suspension movement. The inner is with crush tube is what dries out and needs regreasing. What youve basically done is make the outer of the bush twist and turn which will wear out the bush and introduce play where there shouldnt be any. It should be firmly contained in the arm with no movement..

[@StudioVRM]

That's the theory. In practice the faces of the poly bushings get rotated by friction against the arm and it rotates anyway. A lot of bushing manufacturers now recommend deburring the hole in the control arm and greasing it for that reason.

[@fuzzedoutsounds]

@@StudioVRM StudioVRM a lot of these bushes would have been metal sleeved. The bush is designed to be loaded in more than one direction and resist the movement and want to return to its resting state. Show me a manufacturer who uses a crush tube in a 2 piece bush and recommends it to be lubricated on the outer. They reccomend you deburr and smooth out the housing so the bush isnt damaged during fitting as its supposed to be a near on press fit and pushing it in with a sharp jagged edge caused after removing the old bush will tear the urethane and it will eventually split from the tear (long before its service life).

[@richardallen1816]

why not just use liquid teflon on the metal bushings

[@StudioVRM]

You probably could. I haven't tried it on these bushings yet. Maybe I will next time I have a set apart for service.

[@newfie-dean5803]

You could probably put a ceramic coating on the steel bar or in the case of sway bars put a ceramic coating over the bar where the bushings attach. Then once that has dried good you grease it good.

Wow! Nigga

[@Rusiputki]

I'm a bit skeptical, if it worked people would have known about it by now.

[@StudioVRM]

You know, I was thinking the same thing while I was filming this. Lo and behold, after I published the video a few of my friends came up to me and said that they've been doing something similar for years. One of them uses just Teflon tape (with no grease) and has apparently been doing it for the last 20 years. I've been talking to him about racecar stuff for the last 5 years and he hasn't mentioned it once. Go figure.

[@johngalt97]

Reminds me of a clutch cable that had a 'low friction' lining that came loose from lubricant, causing it to bunch up and become very high friction. That tape isn't going to stay put, and will probably bunch up just like the cable liner.

[@StudioVRM]

That's what I thought too until I actually tried it. But once the bushing is pressed into the sleeve, the tape stays put.

[@jhuesmann]

Grease on the outside of the bushing is just a magnet for dirt.

[@jonnykrivan6840]

Considering I hate to ‘belt the bushings to buggery’ onto the control arm - I’m picking there’s no way this would of worked

[@AZsmoothrider]

You are greasing the wrong place! That is not the pivot point. The part you are greasing at 1:55 stays stationary in the mount. It's the INSIDE of that bushing that needs grease and is a pivot point.

[@minatormyth]

Although you are right, it does not really matter.

[@Tixbomber]

The sleeve looked greased when he pushed it in. Wouldn't make much sense to wrap it with teflon tape and not grease it.

[@AlphaMachina]

Typically, as long as there's nothing that could cut or wear the bushing in one spot prematurely, it doesn't really matter. As long as the inner surface of the arm, mount, leaf spring, whatever, is smooth, it's okay if it's greased for movement. They'll typically outlast the vehicle anyway.

[@welcometoreality3450]

@@Tixbomber he mentioned in the comments section that he knew someone who just used the teflon tape ONLY (no grease) that worked well for many years. Teflon is one of the top slipperiest substance known to man & the tape holds it in place very cool idea!

[@tthams73]

You’re not suppose to grease the outside of the bushing! And you don’t use “Marine Grease”. All marine grease is, lithium based grease with “Marine” printed on the label and the list price raised a couple of bucks. Only use Silicone Grease. Better idea! Spray the inside of the bushing and the inner sleeve with Dry tungsten disulfide, let dry and burnish it into the substrate. Then grease. I use 3M Silicone Paste. No squeaks ever

[@circuit-maker7971]

What did you use to "burnish" the tungsten disulfide?

Dont waste your time with Polyutherane bushes like these. Rubber bushes are much better unless your racing a car . Rubber Bushes are quiter and smoother and generate less road noise and you never have to take your suspension apart vs Poly where you have take your suspenevery apart every few years to grease them becasue they squeak . Rubber bushes tend to last about 20 years , so I would rather take my suspension apart every 20 years vs Poly where you have to your suspenion apart every 1 to 2 years to grease them to stop them squeaking. I had Poly bushes and they squeaked every time I drove thru a Puddle and had regrease them every time . I now stick to OEM rubber and dont have to worry about driving in the rain etc and taking my supsension apart all the time to grease.

[@Davesworld7]

Polyurethane is technically a hard gel that cold flows. The companies who sell this crap do so because it's cheaper to make, some thermoplastic person got a marketing idea years ago. They do NOT employ engineers who make use of a huge R&D budget in the millions to design bushings for each vehicle. One can make rubber even stiffer than urethane if they chose to use such a high durometer but then things start to break open such as tack welded firewalls right down the middle. You can't just slap on stiff bushings without considering the rest of the vehicle. I feel sorry for the women who ride with their "genius" diy husbands in these vehicles and wonder why they get fatigued just driving 30 miles. Something like, "yep honey, I'm making it better than the manufacturer ever could, those people and their multi-million dollar research budgets and design expertise don't know 'nuthin". Meanwhile the woman thinks, "Why do I listen to this backyard hack"?
