driveshaft noise

I have a 2011 reg cab 4x4 4cyl tacoma and when im driving like 70-75mph and i let off the gas i hear almost like a grinding noise or like something under my truck is loose. dealer told me they couldnt hear it. anyone else have this issue? I was reading on TTORA that you can flip the rear driveshaft and that might take care of it, anyone done it? pics? info?

 

Maybe a carrier bearing? I had one go once and it really only made the noise when I let off the gas at speed.

Or do reg cabs even have a carrier bearing? IDK. I would grab your driveshaft, shake it, try and turn it, etc. You really shouldn't have any movement. If you are able to turn it at all (assuming you are in gear and parking brake on) you probably have a bad u-joint.

 

my truck only has like 2,650 miles on it.. i was reading on TTORA that you can flip the rear driveshaft around so the yoke slip end is at the transfer case and that worked but idk how id go about doing that..

 

That would void your warranty. Is there another dealer close to you?

 

yea..

 

You're not the only one who's noticed this "grinding" sound when letting off the gas at higher speeds. I noticed it on mine a couple of days after getting my '06 regular cab.

were you able to get it fixed man?

 

The dealers never hear anything. If they admit they can hear something wrong, then they have to fix it, which they of course they don't want to do. They wait till crap breaks, then they will take a look at the problem. How many people had to die before they did the gas pedal recall thing on some of their models?

I bought my 09' 4x4 reg cab brand new and it did and still makes the same deceleration noise. If you're hauling down the freeway 70+ in 5th, 4th or 3rd even and take your foot off the gas it makes the noise, then at least in my case it completly goes away as the truck slows below 50 MPH. I have NEVER heard the noise at 50 MPH or less under any condition. It doesn't always make the noise either but I'd say it seems like 80% of the time when decellerating it makes the noise.

My truck has 35,000 miles on it now, was lifted 2 days after I bought it and the noise has NOT gotten any worse. I learned to ignore it and to keep my stress level down, I stay away from the dealer.

I had started a thread on this noise and some others have as well. I don't think they ever found a perminent fix for it but I honestly don't remember.

 

I have a 2010 SR5 4x4, 29,000 miles with the same symtom. I do hear it at lowers speeds also but only when coasting. I have not been to the dealer yet but plan a trip soon. Will report back.

I would be interested in knowing if any dealer has addressed this issue and if it was resolved.

 

Now that i think about it there was a dealer thing for the noise TSB?? or whatever they call those dealer fix problems crap something or other things.

I will see if I can find it but dont hold your breath.

 

Im dealing with this problem right now. My carrier bearing has completely shit itself. I get a new drive shaft and carrier bearing this week. Wooohhoooo!

 

^^^^^^^^^^^^^ you should start off with the carrier bearing first before getting the drive shaft along. one step at a time man.

 

Im not paying for it. My Service Manager made the decision. He is awesome!!! Its going through my extended warranty. Plus I get a free rental for a few days.

 

Ok I found it. Here is the TW thread.

If you want more details on the actual fix use the TTORA link in post #32 of above thread. Guess TTORA guys are good for more than bashing lifts over 3" after all LOL.

It seems as though flipping the drive shaft gets rid of the noise once and for all. Note this is the fix for the reg cabs. My understanding is the ext and DC guys don't have this particular issue, my guess is because of a different length drive shaft and don't the ext and DC's also have another ball joint as well?? I dunno.

I'm going to try flipping mine and see if it goes away. I need to crawl under my shit and tighten up some other crap making noise when I brake anyway.

 

I only got the truck 2 weeks ago as a DD, so I've been busy changing fluids, plugs, etc after work every night and haven't had time to take it to anyone. It seemed to be silent running over this past weekend, then the sound came back with a vengence today. I really hope it's not the transmission.

 

^^^AGREED!!!!^^^

 

They are even dumber than that.

Name one vehicle on the road built in the last 25 years that you can not bring to a full stop, even with the thing floored, by just stomping on the brake pedal. Yugo's don't count either. Oh and a Veyron doesn't count either.

 

Stay on topic.

I've got the noise in my reg. cab, and I don't worry about it.

 

I just did this about 2 hours ago. Damned if it didn't work! I took the truck for a 20 mile drive afterward and the throttle-lift-grind is completely gone.

I guess the next question is whether this solution causes any long term issues. I don't think it would, but I wonder how long others have run the driveshaft backwards?
