Shake it up

Not a stupid question. No I have not yet but I would think the shaking would be present at all times if it was a bent rim.

It seems like there is no damping of the shocks over these types of road imperfections. A chop in the road, a large pothole or a highway traverse causes a vibration/shimmy/shake that starts in the front suspension and seems to travel through the chassis and the cabin. There has been a reduction during straight line travel and I believe lower speed sweeping turns after the idler arm bracket was changed.

Mechanic looked it over and couldn't figure it out. Guys were honest and admitted to not being suspension experts. They did indicate that pushing down ******* the front end felt like the shocks had no give. They suggested maybe trying to run my tire at a lower psi (I run stock 30) and removing the front jouncers to see if there was some kind of improvement.

I have removed the front jouncers which I believe provided a slightly smoother ride. There has been no negative affects in hard braking or turning with them remove. I know I should probably put them back on and I will. I am guessing at this point. Maybe my shocks are having a travel issue?

I think 30 psi is a bit too low. I think recommended tire pressure is a min of 32.

I'll give it a try. Only reason I was doing 30 because that's what is listed on the door.

Is it really? I gotta check mine tomorrow. I could've sworn I've seen 32.

I forgot the previous owner ripped the tag off the door.

This is all the owner's manual says.

I have 20" wheels stock. They are updated sierra all terrains but my original wheel size was 20" which is 30 psi via the door.

Are you familiar with bad wheel bearings? I left some videos on the previous page.

I replaced my driver side about 2 1/2 yrs ago. It was making a grinding/groaning sound, and I actually felt it in the steering wheel.

Unfortunately my issue isn't so text book if they are indeed the bearings.

i would have said wheel bearing a while ago but in the original post you ruled them out. that would make sense to me.

I didn't see anywhere what mileage you have on it but you could replace the front hubs with some Timkens just as preventive maintenance if it's anywhere near 150k. I saw at one point you mentioned you heard noise when spinning one of the front wheels. That would at least rule them out and they'll need replacing soon regardless.

Hey Tahbro, I would have thought so but I couldn't get any movement with the wheels lifted and pulling at 3-9 or 6-12. I wouldn't think they would cause such a shake over bumps in the cabin If couldn't get any play that way. Did you get a chance to take a look at the video on the previous page? Thanks

moving them with your hand may not show signs but the noise makes sense. I agree with rocket man, a 2005 would be really close if not past due on wheel bearings. hopefully that will eliminate the issue and if it doesn't you'll be set for another 100k

Hey Rocket Man,

Yeah I found that the front drivers side brake pad slightly touches the rotor. Previous owner had the brakes/rotors replaced 10,000 miles ago. I have paperwork to confirm and visual the pads look very good. I am guessing they weren't checked to make sure pads had play in the clips. Ill have to take them apart this weekend and see if I can do something about it.

Truck has 111,000 miles on it. Thanks for all the responses.

So I just order the TIMKEN SP500300 wheel hub assemblies along with new axle shaft nuts #11609826. Can't hurt to change them plus maybe I will get lucky. I am trying a different size moog sway bar bushing K6437 (1.20) for the fronts since there is some play in the 1.25 that are on the truck now. Confirmed with a rep from Moog via my earlier video. For the hell of it I am installing the KYB SS15326 steering stabilizer, replacing the bushings with Energy Suspension 9.8126G and adding the Monroe SA1997 boot. I will wait till after test driving with the new wheel hub assemblies and sway bar bushings in case the stabilizer hides the symptoms.

I put that steering stabilizer on my 02. It did seem to steady the steering a bit with my big wheels.

Those wheels on your Denali are beasts.

Really? What browser are you using? What are you seeing?

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.

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