Synthetic Grease, great tip. and marking the shaft is a good tip too. I've always forgot to do this then have to spin the tires to get things lined up. Good video, Cheers

[@robleekay6271]

Hey, I commented on this 8 months ago. Just to it to the shop 2 weeks ago and had the same thing done as what you did. So far no clunking, they also changed the differential fluid with a full synthetic and slip additive.

[@BrucesShop]

That is very cool.

[@adamm8236]

[@BrucesShop]

That is so cool.

[@scottfloyd4139]

So, I have a 2006 Silverado with the 6.6 duramax and a loud clunk, so I watched these videos and agree with most.. that packing your transfer case full of grease is NOT a fix. I have seen videos of guys shoving raquet ball pieces inside the slip yoke. What I did was, I took a valve spring and measured the distance that the shaft goes in to the slip yoke. I cut the spring and welded a flat washer to each side just to add a little spring tension when it shifts. I AM NOT A CERTIFIED MECHANIC!! though this method has worked for me for the last 2 years and I use my truck everyday in my excavation company hauling gooseneck trailers and our 5th wheel camper with no problems and it fixed my issue. my truck has 280k miles on it now and still going strong with no clunk!

[@BrucesShop]

Very Cool. Well I just putt around town in my old Silverado. 800 KM's (500 miles) since last November. So anything that helps me is noticed.

[@miguelreynoso4879]

Hey Scott, I was wondering what was the valve spring from ? I had the same idea for a fix but wasn't sure how big of one was needed . Seems to me that's a better fix then having to repack it with grease in another 5K miles or so .

[@vistaca760]

Can you guys please make a video of how to do this?

[@SteveRobReviews]

Looks like a part 2 coming up. I chuckle every time I see the marking of the orientation of the prop shaft LOL. I worked on the line out in Ontario put thousands of them in as they went down the line and we just fired them in any way we could, their pre assembled and balanced prior to assembly. I have heard some say it's to prevent an imbalance that was not their before , may well be. People are still putting stored battery's on a board to prevent discharge on a concrete surface Ha . Oh well you sure don't have to worry about that clunk again with all that grease :). Not sure the year of your truck but look at your exhaust manifolds and see how many bolt heads are missing. You always do it right 👍

[@SteveRobReviews]

Excellent comment , you really have to look at all the possibilities for all the different types to take into account what you have outlined. 👍

[@kencress1267]

The driveshaft is balanced not the yolk. If you installed a new driveshaft how would you know if you had no mark to go by?

[@SteveRobReviews]

@@kencress1267 Ken I was only making reference from when the vehicles went down the assembly line but yes the whole driveshaft including the yoke is balanced as an assembly then installed including center hangers if needed. The yoke , u joints are cast and machined to specs in combination with the balanced driveshafts. You generally dont see balance weights on yokes or u joints . Cheers

[@brianbrown8763]

So I don’t need to Mark / orientate ?

[@b1782w]

Would this sound resonate thru the shaft and cause me to hear it from the rear? Seems to be the noise I'm hearing but I'm not sure..

[@BrucesShop]

Gosh I don't know. This one was apparent on kind f a neutral load.

[@pleaseenteraname4398]

Sorry to ask on such an old video but I have question. Was the clunking noise when you put the truck in drive or was at other times?

[@BrucesShop]

Hmm I think is was when i moved forward. Sorry i don't remember any more.

[@Gottacacheemalll]

I went over a bump , my lever was on 2h and it just started clunking real bad. The lever was also jumping as it was clunking. I could only drive my truck on 4WD then it just went away. Now the lever kinda clicks. What do you think it is?

[@BrucesShop]

I do not know. I think you may have to take it in to a mechanic.

[@jifi-0178]

Glad this worked out for you. My former truck had the same issue - 2007 Silverado 1500. Yes, the problem has been around for a while. TSBs (tech service bulletin) were finally issued, but I don't know about a recall. The stealership tried the grease approach at first and it helped a little. The next step was to replace the yoke. Luckily, my vehicle was still under warranty and this was covered. Problem solved. The plating was incomplete or inadequate from the manufacturer on the splines and a binding/sticking occurs when the shaft finally slips with a thump. From what I can see by the forums and comments online from people looking for an answer, a TON of Ford and GM trucks experienced the problem.

[@BrucesShop]

Thanks for the kind words. i have had guys attach me saying i am nuts. But when you have a 19 year old truck you try everything that doesn't cost a bunch of money first.

[@johnredmansr1922]

I have a 4x4 2004 gmc duramax 2500hd it makes some knocking noise when I put it in 4 wheel drive, any suggestions?

[@BrucesShop]

Well they all clunk when you put it 4X4 as the transfer case connect to the front drive line. So it depend how bad it is. Do you have one you can compare it too?

[@kirbylane9451]

I think I would have invested in a new tail seal for that driveshaft while it was out. But that grease trick does work. I've done that to an older model Chevy years ago and it definitely helps to cut the clunk.

[@BrucesShop]

Thanks Kirby. I got the info from a chev mechanic

[@jglaboratory]

Is it a clunk when it leaves 1st gear

[@GsxrJuice]

Can I do this to the front drive shaft as well going into the transfer case

[@BrucesShop]

I don't think it is on a slip yoke. Just have a look

[@makingtechsense126]

Thank you for making a video about this.

[@BrucesShop]

My pleasure!. I hope it helped. At a certain age they are all clunkers. LOL

[@edjo3430]

Is this yoke supposed to be lubricated by T-case oil? Meaning, this grease you put on the drive shaft isn't going to get into the trasfercase is it?

[@BrucesShop]

Good question. I think there may be the smallest of movement. This is actually a GM fix. I did this 5 1/2 years ago so far so good. Thanks for keeping me honest.

[@thaigrass]

I tried this fix on my 98 Sierra 1500 4x4 too but when I tried to push the spleen end back in so as to hook the rear universal joint clamps back up it would not go into the yoke enough to get the rear universal in place. Tomorrow I will have to try hooking up some rigging and use a come along to pull it in if nobody else has any better suggestions? I already had to take a bunch of grease out.

[@BrucesShop]

I did not completely fill mine as you do need a bit of room in there for the grease.

[@edwinmendija8087]

Just wondering...would it be possible that that grease be supplied in those grease gun tubes? Would've been so much easier.

[@BrucesShop]

It isn't something I would want it a tube.

[@BrucesShop]

[@sbond1963]

you mentioned transmission fluid falling out when you removed the spline / yoke. so if transmission fluid is coming in contact with the spline what will stop that grease from possibly getting into the transmission?

[@BrucesShop]

+Bondo The seal is right near the end of the trans. I think the grease helps right at the output of the shaft near the end of it. GM endorses the job ---that is one thing I know

[@stryker1953]

Yep. Every mechanic I have talked to say not to use grease because it will get into the transmission. Just use transmission fluid or live with it

[@jayb198083]

At what point while you were driving did you get the clunk? I have a 99 Yukon that clunks or feels like a jerk at cruising speed of around 50mph. It happens when the rpms drop down after shifting through all the gears. Could my problem be the same as yours?

[@BrucesShop]

+Scott Martin mine was just as I was moving forward under minimal load.

Great video bruce. I have an 01 sierra with an aluminum spicer driveshaft. I marked the slip yoke and put on a new yoke side u joint......I wasn't able to get the parts until this morning and my truck sat out in the rain......now that I have re-installed my driveshaft it will not turn over.......my idea is 1 of 2 things...........water got into transmission overnight or.....there is one spindle on the yoke that appears wider than the rest like it is worn down......at first I thought that it was normal and there should be a spindle on the receiving end, but all spindles on receiving end seem identical......possibly I need a new yoke.......any thoughts or comments appreciated

[@BrucesShop]

+Craig Poeppelman I don't know Is there a wider notch in the transmission to match that grove in the spindle?

[@craigpoeppelman6270]

no there is not, but the yoke did fit in nicely just where I marked it when I took it out as of now I think it is wet spark plugs thank you for replying! From my sources (a couple friends and the tow truck guy) they say my driveshaft looks good and it is some sort of electrical problem from all the rain I had overnight

[@glenwatkins969]

Bruce Pender see

[@xzx4020]

Would this cause vibration while driving ?

[@BrucesShop]

Just a clunk on take off. for me

[@dansportdr123]

I got 2 questions. 1 is there any risk of blowing out a seal, the slop is there intentionally since the driveshaft distance changes as the rear suspension moves up and down. If you fill it with non compressible grease could it damage something? 2. I hear about this nickel plated yolk solving the problem. How would a coating fix a slip issue? Does it just not slide as easily??

[@BrucesShop]

I get that. I made this video in 2015 and still no trouble. I did not fill the void just lined it with grease. I think it is just taking up space where the wear was. Thanks for watching

Hey Bruce, I've had this awful clunk since I bought my truck (2001 Silverado 1500 Z71) , and I think this just might be the remedy, now that it's done and over for you how much grease would you say to use? 'Bout a half of a can of that AC Delco grease?

[@BrucesShop]

No actually just a couple of blobs. 4 tbps's like cooking. Good luck. It won't hurt I think the spline sticks on the outside of the seal.

[@SuperKirschman]

I've been researching this for awhile as I have same clunking on my 03 silverado. From what I've seen and read the only thing you are supposed to grease the yolk with is transfer case fluid. Mine has the auto 4 wheel drive and it takes a blue transfer case fluid. The grease will make its way into the transfer case and contaminate the transfer case. Alot of people say to replace the yolk with the nickle plated one as recommended per the service bulletin. I'm thinking my noise is coming from the differential

[@BrucesShop]

This was like the 2005 steering wheel "clunk" which was also a grease issue. But my 2013 2500HD pounds when shifting since hitting a pot hole.

[@BrucesShop]

Check the transmission mounts and cross member . I had that a few years ago too.

[@usmcoth]

There are two large rubber pads up underneath that look like they would absorb shock which looks like there could be a couple of inches of play. I think that is the 2nd part of the problem. The hard shifting, I presume, is coming from the shift solenoids?

[@BrucesShop]

Did you tighten the bolts at the bottom of the mount? I think you probably did

[@bearwhocares9539]

Me here. Did You ever fix the problem?

[@coltonkelly6303]

Mine makes a clank like a chain is hanging down, when im going down a bumpy road sounds like chain swinging against the frame i checked the spare tire holder thats not it any one else heard this?

[@BrucesShop]

You will find it.

[@smilinbrad7712]

It's the anti clatter clips on the disc brake pads. Use new ones, no rattle clatter.

[@MSNYC11101]

HY guys, same issue here. 2012 Silverado 4.3v6 wt. when I apply gas after coasting I hear a clunk coming from under the truck. Mechanic said it’s typical of Chevy. Thanks all.

[@BrucesShop]

OK Good luck This video is 8 years old and i still have the truck. :-) It is 26 years old.

[@MSNYC11101]

@@BrucesShop Very much appreciated, thank you!

[@wendellgreenidge3362]

Did this actually fix the problem?

[@BrucesShop]

It did make a huge difference. Remember this is an old truck.

[@happytrails1963]

hope this fix, when i put truck in gear have a big clunk its so bad

[@BrucesShop]

Good luck. Yours sounds more major that mine. Give it a try

[@bigphokus]

I'm going through the process of getting to the bottom of this.

[@BrucesShop]

There are a lot of causes. This one helped me obviously.

I change the u joints with the greasable ones since its off

Right Good idea.

[@crazyobservations3080]

Mine has a zert.shot it full of fresh grease problem solved.There is a stationary shaft off the trans and then the slip yoke.extended cab Z71.

[@BrucesShop]

+crazy observations Great. Maybe next for me.

[@hellhellya1]

Your only going to get to do this once in the truck's lifetime. Plus packing grease this way forces grease through seal if over packed

[@tractyzadorozny2972]

You got lucky Bruce with the bearing cap

[@BrucesShop]

Tracty Zadorozny I know.

[@702johnny]

+Bruce Pender , What kind of clunk is caused by the yoke not being greased? I have a 1997 k1500 4x4. when I come to a complete stop and then take off, I sometime have a clunk sounds.. only when I come to a complete stop and take off again. would this be the most likely cause?

[@BrucesShop]

+johnathan wood That is what mine was. I have had 2 though. The trans mount on the transmission cross member was loose once too. Old trucks have there own personality

[@702johnny]

Thanks for the info. I thought for sure it was my rear end. Good thing I did a little research.

[@rc_anykine8840]

Johnathan Wood did it work?

[@gordb4343]

Uh did it fix it

[@BrucesShop]

Well this video is 8 years old. Now to be honest after I did this another quierter clunk showed up which was the cross member bolt.

[@tumyung9666]

GM had and has a problem with excessive ring n pinion clunking.

[@BrucesShop]

Yes They do. Now this truck is 18 years old so I nurse it along.

[@anthonyskorner4511]

And dodge isn't much better if any. Ford may be okay idk. I just know the 8.8 & 9" are supposed to be strong.

[@skuunker]

this procedure will work in a 4wd 2005 silverado?

I don't know. Mine as you may know is a 98

Ok Thanks. I have heard of softer ones.

[@edmaster256]

We never know if it works or not ?

[@BrucesShop]

true

[@John12ram]

Yeah when you do this make sure you don't feel the back come up with grease there's a air pocket for a reason that allows it not to lock up just Grease the spines do not put grease in the back not unless you want to buy a transmission

[@BrucesShop]

Right. Great to mention that. This video is 6 years old and all is well so far. I was concerned when I did the job.

[@John12ram]

Yes sir but I do want to thank you for the video that you had given people I just figured I would throw that information in there God bless

I love my 2000 Silverado but I started just fixing stuff that falls off lol . Scared the hell out of me when my spare tire fell off

[@BrucesShop]

Right they basically just hang there eh!!!

[@anthonyskorner4511]

Scared the lady tailgating me 1 time. Maybe she won't tail gate anymore. Lol.

[@tumyung9666]

hmmmmmm, so your masking the problem with thick grease. how will the grease effect the trans fluid???

[@BrucesShop]

Well so for so good. I thought the same thing but GM endorsed the job. The video is almost 2 years old now. Thanks for the comment.

[@thomasmason7626]

When i replaced my spider gears in rear differential my clunk disappeared

[@BrucesShop]

Right on. That is a the best move

[@noaolvera1750]

Thomas Mason what year was yours I want to grease my drive line but I think I have a bad rear diff as well do you recommend I grease it like in the vid ?or what should I do ?

[@minnesota7010]

Tom How much did that cost you bro... Thanks

[@MakeFamous88]

Did this fix your problem ?

[@BrucesShop]

Yes. There are so many clunks on old trucks. It helped a lot.

[@tonyharris46]

you didn't do an after to show us ofnit worked......didn't work?

[@BrucesShop]

Well i am still driving it 6 ears later. This video was made in 2015. Now the trick is to do maintenance and not wait for a repair.

[@fish4fun354]

I thought the grease could get into the transfer case and ruin the fluid but if you said GM mechanics recommended it I guess it should be fine.

[@BrucesShop]

I did this years ago.

[@BrucesShop]

2015 and still going.

[@fish4fun354]

Dealer told me to use the Acdelco Super Lube 10-4057 to do what you just did. They didn't have what you did.

[@fish4fun354]

Also read on one of the bulletins that you can only use grease with ATF only. Heard the fix is to use transmission fluid on the splines or get a nickel plated yoke. But that's if it were to get passed the seal and it could ruin the fluid.

[@drewgriffith4642]

Man violates shaft hole with broomstick

[@KRich408]

Also if you have 4 wheel drive the yoke is in the transfer case not the transmission.

[@jackblaylock3696]

Thanks Ken!

[@edkay3601]

This will work for awhile but another way to kill the clunk is to change the trans fluid and add a stop sticking automatic trans valves additive. if your transfer case uses automatic trans fluid add the free sticking trans additive to the transfer case.

[@BrucesShop]

You could be right. This video was published in spring of 2015 and it is OK but i don't put a lot of miles on the truck. Thanks for commenting.

[@sbond1963]

What additive would that be?

[@edkay3601]

Lucas Oil Transmission Fix has worked for me.

[@skatewithvanz]

Lol , and yeah it says 5years ago on my iphone

[@mattyboyz16]

Crazy that splines arent greased from factory

[@BrucesShop]

I think it picked up some wear over the years and this keeps it from binding.

[@ralfie8801]

mattyboyz16 That's because the splines are tight when they're new, they do get lubed with transmission fluid from inside the transfer case.
