Well I figure if anyone should know or could tell me it has to be the GM Expert..

 

so as the topic ask, what is the best lube for Rubber Mounts? as in Body Mounts...

Something or someway to stop them from creaking squeaking and DRIVING ME NUTS!!

is there any homebrew fixs? I have been thinking of plastic placed between the mount and the body and the mount and the frame...

Say like a nylon type or what????

 

Please give me the once and for all fix for the things.. Thanks Kindly

GM has no recommended lube for body mounts, so I'm not so sure I'm an expert in this case. :D I would use a silicone paste, but I don't believe I've ever seen a truck with squeaky body mounts. Pop or snap, yes, but not squeak. How do you know for sure it's the body mounts?

I use silicone spray lube myself and I also use it on door seals, especailly during the winter as it will prevent your doors from freezing shut in cold weather too when seals get wet and tempature drops. It works like a dream for that.

The best thing in the world for weatherstrips is a product called Krytox. GM carries it as part number 3634770. Expensive, but better than spray silicones.

Maybe but silicone is cheap, easy to find and repels water well and it is likely that the GM product has silicone or Telon in it or a mixture of both of them. With spray silicone, a lot of it is vehical (propellant and carrier to deposit the silicone) so I usually go over it heavy or sometime twice but it will last for some time too.

It is not really a squeak but for lack of a better way to describe it I used the word squeak.. (my bad)

it is like creaking or popping, a rubbing/rattle type noise at low speed and braking, also I can dup it by grabbing my running boards which mount to the body mount bolts.. I can spry the mounts and it is silent.. but it does not last but just a day or so...

It done this before I put them on and still does it. I only have about 1400 miles on the truck and can not believe they make so much noise.. sounds bad.

 

The big washers are all rusty they was rusty looking Brand new... on the dealers lot with 5 miles on it.. not sure if it matters or not but I would have thought they would have had something on them to stop that?

 

So I need to find a fix for the thing. something that would last for a couple years?

I will be looking into this until I find a fix, I thought about a thin shim of nylon or plastic or leather or somthing between the contact of the rubber and body and frame?

Just don't know what to try, and what to use for the shims? or if any of it would work or be worth while?

A thin teflon sheet trimmed to fit would do the trick and last a long time too. YOu could lube/grease the washers and see if that helps as with heavy grease it should last several years.

Bingo. We get plenty of these in with aftermarket running boards and complaints of noises. We don't attempt to fix them because they're not factory stuff, but I'd check and make sure the bolts used through the body mounts are not too long, passing all the way through and bottoming out. A little grease (choose your favorite) under contact points might help.

I understand what your saying but GM Does infact offer the same (mounting type) steps as a option..

 

Anyway I did not change the bolts, they are the factory bolts. also as I said before it done this before the addition of the boards/steps.

 

Where could I find some thin sheets of teflon or such?

 

Thanks for the help

just my 2 cents but ithik ive got the same prob on my 99ext z71 and my squeak is on the driver side corner of the firewall me and a dealer service adviser think its the e-brake assembly that comes up through the firewall i have tried some silicone spray on the rubber around the cable where it comes into the truck but i havent taken a great pain with it but it is very annoying when turning or going over bumps at low speeds just pop the panel off where the e-brake pedal is and pull the carpet back and have someone bounce the truck so you can listen .let me know if this is the same as my prob.

Yes, GM does offer that TYPE, but they apparently ain't the same because we have no problems with noises from those, just the aftermarket type. I haven't investigated the differences, so I couldn't say exactly why.

      GM Hard Folding Tonneau by REV review

      By cautious optimist · Posted

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
