Shake it up

[Tonyrodz]

Yeah I had to open it on YT to view it too.

Me too.

Try to click on the top left words in the video screen so it opens the video in a new tab. Click the word 'Wobble' and the word 'Noise' in the top left of the video screen. That should open it in a new tab for you and maybe make it viewable.
YouTube reported I couldn't watch the video on TYF as Massfloefi published it that way. Your browser may just not be telling you can't view it on TYF.

Sorry fellas I didn’t realize it worked that way. FIXED.

Was the problem present before you changed your lower control arms?

Yes it was.

I see it now. That wobble reminds me of my wobble I had, but only during cornering. it was a wob, wob, wob, wob, wob. A new wheel bearing fixed it. Next time when you have time, pull off the wheel, caliper and bracket, and get it down to the hub. Sometimes the weight of the wheel can mask the play in the wheel bearing.

Hi Mooman,

Changing hub assemblies this weekend with Timkens. I am also putting new caliper guide pins on and lubing them with 3M 08946 clear silicone paste because I am getting a slight rub from the inner brake pad on that side. Hopefully not a problem with the caliper itself.

any update on if the wheel bearings fixed the issue?

Tahbro,

I replaced both sides with timken yesterday. No change. There was bushing squeak from one and some bearing noise from the other. No play in my hands. I even hit the old ones with a 4 pound hammer to see if they had any play. Nope.

So I started to think about the conditions and dampening. I might have found my problem.

 

[Massfloefi]

The bottom part of the bushing is completely shot when you squeeze it and you can clearly see that the metal cup the upper bushing is sitting in is bent away from the body mount.

I also have a video but the GoPro is acting up. I will post one when I can.

 

[Massfloefi]

Enlarge the video and slow down the play speed to 0.5 and you can see the play/shake better.

Possibly. Are you gonna try to change it?

No I don't think so. I haven't seen enough videos about how to do it safely and properly. Thinking about having Straub over in Keyport replace them all.

I've had it with this truck. Wish I could find a performance shop who can tear into and finally been done with this.

I had a shop do mine. They used to be in Toms River.

Noticeable difference after they were changed?

Sorry, I misunderstood what you meant. I thought you were talking about the motor lol.

 

[Massfloefi]

I don't know much about all this, but you may check your body mounts. Maybe one rotted and is causing uneven vibration distribution around.

I think you may be right. I posted pics and made a video on page 5 with noise heard and shaking at the suspected bushing. I'm sure they all need to be replaced on a 13 year old northeast vehicle.

Body mounts and radiator supports just arrived.

Where'd you get them and what was the cost?

I thought I was going to only change one at first so I purchased it from Amazon for $48 and the rest from Rockauto for $430 including express shipping. You can save a couple dollars if you choose to a slower shipping time. Doesn't make any sense to just change one since you literally have to loosen every body mount and lift one entire side of the truck in order to change one.

Dorman claims that the 924-040 bushing is only applicable for positions 1 through 4 on my application. After consulting with them directly they can only guess that the upper bushings has a different compression rate and should be fine if I change all of them. I agree since polyurethane kits are all the same compression.

Reason for choosing Dorman over GM bushings is because of price and the fact the GM claims some of the bushings have been discontinued. Well I asked GM Parts Giant if I could just use the other stock bushings in place of the discontinued ones. Their response was useless with no info either way.

I will post after install with results.

Nice that you will be doing them all. Really hoping this fixes your issue once done.
