TSB Drive Shaft Clunking

I am experiencing this as well. I will be stopped and after a second or two a clunk from the back end. If I let off brake slightly and move forward even 6" and stop, same clunk after a second or so. I can repeat this exercise several times and it happens the same.

 

Youd think after a while Toyota would get their shit together huh? But no this is an issue from 2010 to 2017.

 

I posted this in the TSB page a while ago. fixd my problem. there was a mileage cap for them to do it for free. ill look for the TSB. i got a brand new driveshaft and prop assembly.

 

Heres the TSB. it was extended to later model years

 

This is my first Tacoma and im trying to love it but it's not been easy. Lifted it and had the 25-40mph vibration so I took it off. Might have to go back to full size or look at the chevy twins.

 

I think I'm having a fuel system problem intop of it.

If one more thing goes wrong with this truck I'm selling it. I'm going to stick with Ford.

This thing is like a jeep, wicked cool but a POS

 

@58 Siesta is right. It's the transmission shifting after being at a stop.

 

I have had this same thing with my 99 and now with my 2011 Tacoma's . Both auto tranny's . I have to agree with the statment that the tranny is down shifting after coming to a stop.

 

My 13' has done it since new aswell, I chalked it up to axle wrap. It's very inconsistent and hard to repeat but yeah it does feel like someone tapped your bumper from behind.

 

I have the same "bump from behind" issues, and I now have an occasional slam in between 2nd and 3rd when driving on a curvy country road at 30-45 mph. It just plain feels like the transmission was free-wheeling before finding 3rd gear again and then wham! It's good for a day or so. My last "bump" was so severe it actually spun the tires when I was leaving a stop sign. Scared a pedestrian to death! Could this all be tranny related!
05 TRD SR5 155,000k

 

The slipping of the rear tires would seem more like axle wrap than a trans issue.

 

Actually had the frame replaced about 18 months back; leaf springs, shocks and all. Could the springs not be seated properly?

 

Some more food for thought. I got Toyota to replace my driveshaft under warranty and the bump when I came to a stop is completely gone. Got 75k miles on the last drive shaft. I did replace u-joints and carrier bearing on my old one, and made no improvement regarding the bump.

My next issue is now to fix the 15-25mph vibration. Got Toyota to replace engine mounts on Friday. Doubt that will fix it, but why not.

 

So I decided to flush & fill the transmission fluid. Ended up replacing both fluid lines, all fluid, and power steering lines, etc. Quite a few small leaks.
This appears to have eased the issue somewhat, but time and regular driving will tell for sure. I just consider this a long term investment. Driveshaft may be next, but with no warranty, it's going to be on my dime. Still love my truck !

 

Hi all!
Just my experiences with this issue. Same general description; start off- slight "thunk" or "clunk" after a moment with a definite "feel" of it in the seat of my pants. Stopping- various delays in "thunk" or "clunk" depending on speed or rate of deceleration. I have a 6 speed and can make the "clunk" by downshifting.
Same as most; I looked under the truck, in the bed, under the seats, in the compartments, etc for something rolling around.
Took it to my mechanic and we both took the drive shaft off to grease the slip joint. Slip joint was well lubricated. Cleaned SJ and re-greased with synthetic. No change. Ordered

$19 Ford's XG-8 PTFE Lubricant - 3 oz.

Ford's XG-8 Teflon grease and re-greased. No change. Re-greased with MORE XG-8. NO change. Dropped drive shaft and cleaned and re-greased with Moly. No change. Four re-grease jobs in two weeks with varying degrees of "clunk".
Called Toyota and asked to speak with someone about type and amount of grease to be used, as there are many opinions and I was running out of patience.
Mike, in the parts department, told me that he had a Tacoma and was waiting for the "clunk" to start, so he could get the new, revised drive shaft and that I should call service and complain/inform about the "clunk".

I did just that.

Called and explained my situation and made an appointment for the next day.

I arrived and went to the desk to check in and told Sean the story. He tapped away on his computer and told me he was, "looking to see if there was any WEP for my truck", as there was no TSB for it. "Here we go...", I thought.

A few seconds later he says, "yup, you have an WEP (Warranty Extension Program) so, as long as we can recreate the problem, you're covered!"

They took my truck for a spin and called me back to tell me that the new driveshaft is ordered and they'll call when it is in!

$1623 without installation-- cost to me= $0 dollars 0 cents

My truck is a 2009 Double cab Shortbox with 80,633kms

Today is July 27, 2018

Try talking to your dealership about the Warranty Extension Program as the drive train is covered if you have this problem.

Hope this helps!

Man, its been eons since I was here last. Kids and too much work will do that to you I guess. Anywho. I wanted to throw out there what I am experiencing with my truck and see if anyone has some ideas. I have read through the axle wrap issue threads, rear clunking noise threads, front end vibration threads and I have not found one single thing that seems to cover my problems. Preface to this, before taking my new job, I was a service advisor for a couple high end dealers. I did this for about 13 years so I know all about online diagnosis and how it can lead you down the wrong path. Since I dont have my 'ins' anymore, I thought I would start here.
I suspect I have 2 issues, the second seems to have started more recently and does not seem to be related to the first. The first issue. It happens consistently. When I first drive my car, I reverse out of my driveway. I put the car in reverse and hear, and feel slightly, a metallic clack type noise. I reverse and put my truck in drive, and as I start to move again going forward, I hear the same noise. It happens only once when going from P to R, and once when going from R to D. When I accelerate, I do not have any vibrations, rotational noises or anything like that. I get to the end of my street and hit my brake pedal, going about 20 mph and hear that same clack noise. It pretty much only happens with a momentum change. It has done this for quite awhile, a year or more and does not seem to be getting worse. The truck has 126k.

The second issue- This happens consistently. It started a little bit more recently and seems fairly faint. I noticed it about a month or two ago. It does not seem to be getting worse. When I am slowing to a stop, from about 20 mph to a stop there is a very faint vibration. I know the first conclusion would be brake vibration, which I am certain it is not. I can let off of the pedal and coast at speeds of 10mph and lower and feel it as well. I feel it slightly in my seat, and a little bit more in the floor.

Any ideas would be appreciated. I suspect the next step is for me to get under the car and have the wife put it from P to R and move a few inches, stop, go from R to D and move a few inches to see if anything sticks out. I would rather check here first before jumping under a moving vehicle.

 

I think I may have the solution to your first problem, as I experience the same thing, myself. I mentioned it to my mechanic at the same time that we did the slip yoke. I'm pretty sure what you are experiencing is a loose brake pin. I was told that there is a pin that holds the brake pads on and that, over time, they bend or loosen. The sound you are hearing is the movement of the pads until they "settle" in the direction you are moving. This is why you are getting the sound once whenever you change directions. Change the pin and the noise will disappear, I'm assured.

Thank you for the feedback. I will check into that and see if that is the culprit.
I am scheduled tomorrow to have the driveshaft inspected. I will mention it to the dealer then.

 

Update on the "clunk from behind":
Toyota replaced my drive shaft with a new "improved" version. They must have recreated the problem when I brought it to them, obviously, but they didn't retest the vehicle afterwards. I picked up my truck and on the way home, it was doing the EXACT. SAME. THING.... no change. I got home and was able to recreate the sound by rocking the truck back and forth as violently as I could, manually pushing on the tailgate.
I asked my wife to help me, by pushing on the tailgate, while I was under the truck. Little wimp couldn't do it, so I asked her to get under the truck with her phone and record where the sound was coming from and then sent the video to my mechanic. He asked me to bring it to him and when I did he got under the truck and I rocked it back and forth.
He told me to go home and tighten the U-bolts that hold on the leaf springs. I had the TSB springs replaced a few months before. I went home, snugged them up and...... BOOM!... no "clunk", no "thump", no "squeak", no vibration, no NOTHING. It was BLISS!!!
So, I got an updated, brand new drive shaft that wasn't needed, which by the way, only has two zerk nipples now if you're looking for them, and the fix was tightening loose U-bolts.

So, if you are experiencing the drive line "clunk", especially if you've had any work done that requires the removal or loosening of the U-bolts of the rear suspension, try this... it may just save your sanity!

Cheers!!

I have a 2018 Tacoma V6 Auto extended cab. I have the rear sounding driveline clunk too. Normally I have heard and felt it (as others have posted) when almost coming to a stop. Today on the way home, I heard and felt it when I was beginning to accelerate from a stop.

What are the torque values of the rear leaf spring U-Bolts? I'd like to check the torque on those first before I bring it into the dealer. TIA.
