Wuh wuh wuh sound

My truck has a rough country leveling kit. 305/55/20 terra grappler g2's and I have a weird wuh wuh wuh sound. It seems to be at all speeds that are fast enough for anything to even make a sound. We'll say above 20 mph. ECGS bushing has been installed along with a new left front wheel bearing assembly. The left front wheel bearing wasnt really all that bad but it does have some drag to get the bearing assembly spinning so I went ahead and replaced it. I took the right front bearing assembly out and spun it and noticed very little noise or drag. Am I just not used to this aggressive tires? I've had some pretty serious a/t tires before but nothing this wide. It seems to me like the roar would be consistent with speed if it was just tire noise but this seems like something more to me. Rear wheel bearings? Any way I can check those without a complete tear down? Up front is hard to check for me without pulling the hub/bearing assembly. I've read of the rear bearings being a pretty common failure on these trucks. Also I had an alignment and a new set of wheels put on yesterday. The sound was there before and it might be slightly worse now but not enough to say for sure. The truck also pulls left. Anyone see any issues with the alignment that might be causing the pull? Steering wheel is now off center as well. Before, it was perfectly straight.

 

Find a set of oem wheels and tires you can put on for a 20 minute test drive.
That will either confirm or eliminate the tires, as the issue.

 

You can try posting a video of the sound

 

I will try to get a video that shows the sound. I really think its a rear wheel/axle bearing.

 

My vote is rear bearings.

 

Wuh wuh wuh sound

You sir, have an acute case of "dub step". Just wait for the drop and eat the strange pill that cute girl handed you.

 

Sounds fun but I'm not sure it'll solve my truck's issue.

 

I might get ballsy and just pull the left side rear apart and physically see the bearing and go from there. Sucks to think I'll be doing the job twice but at least I'll know then for sure it's bad. If I had any good friends with a Tundra I'd swap the wheels but all my friends are losers and drive sissy trucks like Ford's chevy and dodge. With the axle, brakes, and the entire front diff spinning I can never judge the front bearings until they are out and laying on the garage floor. Maybe I'll just do that on the rear.

 

It's too bad I can't find a rear axle "kit" for our trucks. I've seen them for titans. Simply unbolt the axle/hub/ backing plate and slide it out. Slide in the new one and put the brakes back and you're done. The ones I've seen for titans are <$250. Well worth it in my opinion.

 

It’s probably your tires cupping.

 

I'm starting to believe it is my tires and I'm good with that. If I knew for sure that's what it is. Only way I'll know is to check the rear bearings. 190k is alot of miles for anything. Especially a bearing that's prone to failure on our trucks. I've spoke to the original owner who bought it new. Only thing its had in 190k miles is a ujoint and brakes and tires. If it still makes the noise after seeing and possibly even replacing the rear bearings I'll call it tire noise and drive it till the noise either goes away, gets better, or flies apart!

 

Jack up you rear, put it on jack stand, rock you wheel Top and bottom. (Top push, bottom pull then bottom push top pull) that’s the real way to test wheel bearing. If there is no play the wheel bearing is good, the front rock left to right to test tie rod.

 

From my experience I catch them way before they get to the point of having play in them. At work we spin the tire and feel of the front brake chamber to feel for vibration. I catch front wheel bearings well before there is any noticeable end play. Can't do that when it's spinning an axle and a differential though. Maybe I'm too paranoid over wheel bearings but I have alot riding on them.

Check post 12, might be worth buying a set on Craigslist of well used stock rims with highway tires just to test. Then you could probably flip them for what you paid or take a $50 hit.

 

Where ya located? Maybe someone close by has a set you can borrow for 5 minutes?

 

Most likely your tires. Mine are screamers and definitely have that exact description ( hilarious btw). Sounds very similar to a bad bearing

 

I'm in Morristown Tn if anyone wants to make a few dollars I'd be willing to pay just for the peace of mind to know that it's just tire noise. Sad part is I just sold a set of rock warrior wheels and like new Michelin tires that came off a recent wreck. I expected the East Coast Gear Supply bushing to eliminate the noise and I had a ton of play in the left front axle before installing the new bushing. I double checked all of that work and it did make a huge difference in the noise/vibration. Now it's a different noise and I really feel like it's coming from the rear of the truck. I tried recording a video of it but it's impossible to hear it over the flowmasters. If I can't get some loaner wheels and tires I'm gonna throw rear bearings at it. Can't hurt and I'm sure with the miles they'll have some wear. Also what about draining the rear diff? Would the fluid show the metal from the bearings or are they sealed off from the rear diff fluid?

 

I wish I were closer, I’d loan you your RW wheels back to get to the bottom of this.

 

It's all good. I'm very picky and its probably nothing to worry about. I done this same thing on my last 2 trucks. Go through them and make sure they are in good shape. Then drive the wheels off them. If it's a bad bearing that might literally happen.

 

I've had 3, 2nd gen Tundras. The first one was a 2013 with 12k miles on it when I bought it and low mileage when I traded it in. I guess that first one ruined me. Now I've bought high mileage trucks and expect them to run and drive like that first one.

 

I'm gonna catch a ride to a local used car dealer and test drive a Tundra for about an hour..... There's my test wheels and tires. I'm dying laughing at this thought.

 

Well I ordered my ecgs bushing, and have the wuh wuh wuhhhhh sound. I usually notice it decelerating at 20mph.

I probably should have Checked to see if it went away in 4wd, but I'll check in with OP in a few weeks once I do brakes/bushing/diff fluid change

 

I'm taking the needed tools home from work today to do diff fluid changes as well. Maybe the old fluid will show me where to look.

 

OP, a few things you might try if you haven't already:

1. Run the truck for several miles & hit your front & rear hubs & axle tubes with a temp gun. Record the temps & see if you have a large temp difference between mirrored areas (my temps run within 10*F of eachother). For reference, after a cruise my rear axle housing near hubs runs around 85*F.

2. Try to change road surfaces while driving (chip n seal to blacktop to cement etc.) tune into the noise & see if it changes pitch. If so, may just be your tires.

Good luck on sorting out the issue...

Cheers

 

Hadnt thought of the temp gun idea. I like it! And will give that a swing later today.

 

So I got tired of guessing and wondering tonight. Drained and filled front and rear diff with mobile 1 synthetic. Seen no signs of metal in the rear diff fluid. Discolored badly but no serious metal. Plenty of glitter in the front but I'm sure it was from the failed axle needle bearing. Removed wheels and rear rotors and I have found my noise. Rear wheel bearings. The rear rotors are just barely hitting the backing plate at the top. Indicating wheel end play. Spin the hubs and you can hear some noise. That's as far as I'm gonna go for now until I have the parts and a way of having the axles pressed out of the bearings.

 

If you look right above the parking brake you can see the wear marks on the backing plate. Both sides look alike. It's actually wore a pretty deep groove. Enough to feel the wear with a screwdriver or your finger nail. Now I'll try to find a quality replacement bearing. Wide wheels and tires are hard on bearings!

 

Nice troubleshooting! Hope the replacement doesnt give you any issues.

 

There's a tsb for the rear bearings. Seems my previous 2 Tundras already had the tsb done while under warranty or they fixed the faulty rear bearings on the later year 2nd gens. This is a 2008. My other 2 were 2011 and 2013. My local parts store will have 2 moog rear wheel bearing assemblies today around 5 pm. Probably gonna have to wait till next weekend to tear it down and replace them. Gotta have a way to press them onto the axle. They aren't like the front and are similar to a ford 9" rear end. No choice but to press them off and on. Now to convince the wife a $200 hydraulic press from harbor freight is a smarter buy than paying 100-200 to have someone do it for me. This will be all 4 wheel bearings and the east coast gear supply axle bushing. New front brake pads and front and rear diff fluid changes within a month of getting the truck. Throw in the $1100 set of wheels and I have busted 2 grand getting this one the way I want it. Next up. Spark plugs! 190k on original plugs is a little much.

 

Not to mention the $200 maestro module for getting JBL and the steering wheel controls to work. But in the end this will be the baddest meanest best looking Tundra I've owned. Smooth rolling too.
