Vibration, looking for a diagnosis.

I have a 2006 prerunner four door long bed. The truck has 99,000 miles. The past 3000 miles the truck has developed a gradually increasing vibration at all speeds. The only time the vibration goes away is when i turn right or banking through a right curve. I had the tires rotated and balanced but no fix. Any ideas?

 

it could be a wheel bearing or cv wearing out?

or you have something coming loose in the steering shaft, but i doubt that

i'm not an expert on either of those, but for the vibe to be all the time it would make sense for it to be something between the steering wheel and the front wheels. so just start looken there

 

where do you feel the vibrations..? in the steering wheel, seat, floor...?

 

I feel it in the floor, it sounds like the hum of super swamper tires. It is definetly coming from the front of the truck.

 

definitely the wheel bearings

 

Is this a diy job and if so how much do the parts cost?

 

not sure if you need a new complete hub assembly or just the bearing...call a local autoparts store, this will determine if its a DIY job...

 

I definitely think its coming from the front. Since my truck is a two wheel drive does it have a hub in the front?

 

yes it has a hub, just no cv axle.

 

I have a 2006 4 Door 4x4 TRD Sport and have this problem as well; since 37,000 miles. I feel it from 35-45 mph. The vibration comes in waves. I've had it at Toyota 3 times now - nothing has changed.

Edit: I feel it mainly through the gas pedal, driver side floor board and some in the steering wheel.

 

okay, well the best advice i can give is you is to just start trouble shooting.

type in vibes or some other symptom the truck has into the search bar.

since ur truck is still stock you can probly ignore all the threads about lifted trucks

 

Def wheel bearings. Had to recently replace mine. It would get smooth through cornering but then start again when I straightened out.

I ordered the hub assemby from Oreily's auto parts and I wanna say it was like $90. Make sure you get new gaskets with it, mine didn't come with them so I went to the Toyota dealership and bought them for like $5. I did all the work myself and had to take the old assembly to a machine shop to get the old bearing pressed out and had them put the new one in. From what I found out running around town is that most tire shops don't have a press thats strong enough so I had to take it to a machine shop. That cost me like $50. But I had a mechanic quote me close to $500 to do it so not only did I save a shit ton of money I now know how to do the other one. Its not hard here is a link to a tutorial.
Hope this helps.

toyota says to replace the hub and bearing. the parts are kinda expensive, but you can do it yourself and save a ton on labor.
some people here have changed just the bearing and had luck I suppose.
when it comes time for me, I'll just get the hub too.
I think Timken?? has a replacement hub/bearing assembly (already pressed in)by now. I mailed them about 6-8 months ago and they said they were close to production.
What made a big difference in finding where my vibrations were coming from was the front brakes. I think my rotors were warped and the tire shop kept over tightening my lugs. I replaced rotors and it was all better.
and add that most shops seem to have a problem balancing the stock alloys. Check your torque on your front wheels, 83 ft lbs is it.
good luck

 

thanks
