In the last 2 months, I have replaced the upper and lower ball joints, sway links, and CV axles on my 2008 Silverado. Truck was aligned after ball joints were replaced. However, I still have a thumping/clunking that is most noticeable when turning at slow speeds. After fixing the ball joints and sway links, I attributed this to the bad CVs, but, now that they are new, that obviously isn't the problem.

 

The sound/feel is easily noticeable to me when backing up one way and then turning to go another or when slowly turning into a bumpy driveway or parking lot. Feels like both sides, depending on which way I turn, but is definitely worse when backing with the wheels turned to the driver side then turning them to the passenger side to change direction. There is no vibration, play, or looseness in the steering wheel, no other noises, and steering feels tight. Steering fluid is full and looks fine. At road speed, I cant feel it at all.

 

Got more and more frustrated in my inability to figure this out so I took it to the shop a week ago and they couldn't replicate the issue. I drove with the mechanic and, of course, I could not replicate it for him either. He put it on a lift in the shop for me to look at and everything is good and tight in the front suspension/wheel, it appears. 

 

I'm a little stumped at this point. I had been feeling/hearing the problem for long enough to almost guarantee the shop could replicate it and, instead, it was nonexistent. The shop owner said maybe the grease in the new CVs just needed to get slung around in the boots better, but that sounds like a hopeful thought to me. Oddly, it has been very cold here for several weeks but it had warmed up for a couple days before I took it in. Not sure how much temperature could impact something like this, but I suppose it's possible. 2 days after the shop looked at it, the issue came back again (cold returned too...)

 

Just curious if anyone has had anything similar and what the diagnosis was? Thanks

My ‘08 Sierra creaks and groans when it’s cold out too. I’m pretty sure it’s the14 year old rubber bushings. When it warms up I’m going to rebuild the front end.

We had a guy with a similar complaint last year, turned out his front strut was broken and it was not noticeable until he went to take the strut apart.  The shock flew apart and almost hit him.  Be careful.

I have an 08. Similar issues. replaced both struts (complete assemblies) and no more noises. 

This jars my memory, the strut mount in the strut assembly is rubber, and if there is movement when the truck is jounced, it needs to be replaced.  This can certainly cause a noise.

Could be bushings somewhere, I suppose. Maybe lower control arms or steering rack??

I don't think it's the struts because the problem is most noticeable when the truck is not even moving-- back up with wheel turned tight, stop, turn wheel in opposite direction and clunking happens during that turn. I can feel it in the steering wheel, almost like a binding. Bumps aren't the only trigger.

Guess I need to make sure to keep it from getting wet...

Not the hubs. Shop verified they are tight. What u-joints are you referring to? Front drive shaft? Not sure I'd suspect them because it's a turning-only issue.

 

Anyone know anything about steering intermediate shafts? Decided to grab and shake it today. Should there be any play/wiggle in it at all? There was a small amount of wiggle to it by hand. Hate to take it back to the shop, as I'm afraid it won't act up (again) and I'll look like any idiot (again). Frustrating...

I was actually just going to tell you most likely with your symptoms it is your steering intermediate shaft(most likely upper).  I am sure that is it.  There should NOT be any play.

Yeah. Going to have to look into this possibility. I knew the intermediate shaft was a problem on the generation before mine, as shown in your video, but could find nothing on it for the 07-13 trucks. Watched a video of a guy pulling on one that was not making noise and it had about the same amount of flex mine has. Hope it's not the coupling shaft. That sucker is expensive and there seems to be no aftermarket option.

Very frustrating sorry to hear.  Do let us know what you find.

We have a winner! At least I hope... Went back to shop yesterday afternoon and got the truck to do what it's been doing for the mechanic. He immediately thought it felt like a body mount or bushing shifting with the weight of the truck. Dropped it back off this morning for him to look at. Couldn't find anything bad-- all bushings and mounts looked fine but they tightened every mount and bushing (although he said none of them were particularly loose) and the problem seems to be gone. Hopefully it stays gone. Simple fix for something that has been driving me crazy.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.
