Transmission Clunk, Driveshaft Thump, Worse After Propeller Shaft Replaced, - Page 5 - Toyota Tundra Forums : Tundra Solutions Forum

Unfortunately, I noticed the same problem on my 08 - 4x4, CM. Complete with random brake shuddering (seems like a different wheel shudders each time) when I apply the brakes at highway speeds. It doesn't do this below 55 mph - which is where I mostly drive.

The brakes have been getting better over time and since no one has found a solution that works I will sit back and wait for the moment.

BTW, I had a mid-1990's Nissan Pathfinder, 2WD that did the same clunk/thud thing this truck is doing.

I wish us all luck in smoothing this out and it does seem like a design flaw, rather than a "broken" part. Almost like we are getting axle wrap-up every time we stop.

I used to have a very similar clunk/thud sensation in my 95 4wd Tacoma that I feel in my Tundra. When I first felt it, axle wrap was the first thing I thought it was. Axle wrap was a well known problem of the Tacos so I assumed the Tundra suffered from the same problem being that it is a Toyota.

It would be interesting to see someone install one of theose helper springs for heavy loads that has this clunk and see if it is reduced. I've heard they are supposed to reduce axle wrap.

We all need to try something because Toyota is obviously dragging their feet on this issue.

Arbitration update... had my date on November 18th, I chosen the non-present hearing and just provided all the documentation to the review panel. The panel is an outside vendor (I think in Texas) the reason I chose this method ts too cold again in Phoenix AZ and the truck is not clunking. The clunk returns right about 80-degrees. I was hoping the panel had seen the problem and then would rule against Toyota. Not the case, they are right by the book for the lemon law. I lost the hearing and was told that the part would need to be replaced 4-times to be qualified. My next attempt, when it warms up is to bring it back to the local dealer. Keep bringing it back until something? The dealers are very educated on the law and they seem to be in bed with corporate. Keep calling it something else until our mileage is too high. First Toyota I have had (total of 12 new ones over time) that I am not happy with. My 2002 Tundra was much better.

Another update here. I picked my truck up tonight after my dealer once again dropped the drive shaft and added synthetic grease to the slip yoke. I only drove a few miles home but so far so good once again. I'm still very skeptical as this same fix only lasted about 3 months for me the first time it was performed. The dealer still has to report to technical and or the regional service rep then i'll get a copy of all the paper work mailed to me. My service advisor said they don't know exactly what is going on as far as why the grease seemed to disappear.

Anybody else have any ideas? It's not like an over greased zerk fitting on a drive shaft where it'll sling the grease all over the undercarriage. I know some people have mentioned axel wrap but i don't see how adding the grease would cure axel wrap if it were indeed that.

Bottom line, they had a regional service rep inspect my truck Friday (1/9/09) and he/they think they have a theory as to why the clunk has returned for my truck. They told me that inside the drive shaft there is some sort of foam material and they "think" the grease they packed in there when they dropped the new driveshaft somehow leaked into the foam therefore there isn't enough grease in there now and that's why the binding/clunking has returned. I had no clue there is foam in there and don't know for sure because its just what i was told. They are ordering the grease and will be dropping the driveshaft again this coming Wednesday to do the same thing they've already done once.

I asked what's going to happen if this cures it again for a few months and then returns. I was told that's why they're looking into this, making notes and why the regional guy is involved so he can report to technical. That's all i know for now so we'll see what Wednesday brings....

Any new info on this topic? Since the weather getting warmer, I am noticing the thud/clunk more. I enjoyed driving my truck this winter because the thud/clunk is not as noticable in cold weather. I'm dreading the summer.

I haven't heard back from Toyota on this issue in like 5 months now after all of the coversations last year. They are apparently looking into a fix for this problem. Maybe they lost my number.

Oh well, just wondering if anyone has heard of a fix. FYI - the initial TSB to replace the driveshaft did not fix the problem.

Thanks guys

Its been a few months since my last post (just above yours) and my clunk is back. It actually only took a month or so after they added grease to the slip yoke for the second time. I've been meaning to call the dealer and get the truck back in there but just haven't had the time not to mention, what are they going to do? I've complained to corporate and my dealer has tried to do what they can to fix it but obviously it isn't working. I will say that for my trouble Toyota did give me a free platinum extended warranty. Great gesture, but i don't want to have to take my truck in for grease to be added once a month! i'll post an update when i find the time to get with my dealer..

waited out the winter...which was clunk free! with the temps above 50 degrees its back to hating every green traffic light i see. i also noticed in addition to cold temps...the clunk goes away when it rains and the streets are wet. makes me think a lube thing...possibly suspension, even though it sure feels like the driveshaft (which has been replaced). truck is at the dealership...hopefully the more north we are the smarter the techs.

I found another forum with some interesting news. look at what "coloradobluesky" has to say.

Got the truck back after replacing the second driveshaft and i have to admit the clunk is still there but only barely. the person from corporate i spoke to bfore the truck went in for a repair said they had redesigned the part, (which i thought was horsesh*%) but turns out they may have fixed it. the little clunk that is there i can live with. what a pain in the ars this has been...hope it doesnt return to its past behavior. i have to say i was glad and sad to see others were having the same probs as me...hope they all are corrected...good luck!

whikx250 · #71 (**permalink**) 05-29-2009, 02:46 PM

clunk is back of course...didnt know what i was thinking before. does anyone know if having a mechanic pulling the boot back and cleaning and re greasing the splines will void the warranty?

My 2007 Landcruiser developed the 'thunk' at about 10,000 mi. Very interesting since my wife's 2005 Lexus GX 470 had the same problem develop a couple of years ago. Lexus was aware of the issue, ordered the parts, installed them, and now, some 7,000 miles later she's 'thunk-free'!

My Toyota dealer claims to have a 'fix' for 2008 LC's but not my 2007. In short, if a 2005 Lexus can be cured, why not other 4wd Toyotas?

I plan to confront my dealer with the service bulletin #. We'll see...

muvico · #73 (**permalink**) 07-02-2009, 01:24 PM

is there an aftermarket driveshaft upgrade for it ? drifeshaft thump and serpentine squeaks are the most anoying noises . I can live with any other noise.

I have a 2008 Double Cab Limited. I noticed the clunk on acceleration and when coming to a complete stop right out of the showroom. My first thought was a suspension mount or body mount. Dealers first response was they heard or felt nothing. Passengers have felt the clunk. Next trip I asked to talk to a service manager and not the service writer. Story changed to the grease problem. That did not fix the problem. I'm beginning to think a torque converter problem. After 20,000 miles seems to be getting worse. I will be sure I have the service writer document my complaint each time I go back to the dealer. It sounds like Toyota will be trying to put off a fix and before I know it the warranty will be over. I hope that's not the case. I went with Toyota because I was tired of being screwed by the US dealerships.

The Truck: 2002 Toyota Tacoma, 4x4, TRD

The Condition: Thump, bump upon stopping and starting

The Solution: DuPont Krytox GPL226 Grease

The Story: My truck has had this problem for 105,000 miles. I searched the web and talked to dealers about it, all to no avail. I read here that it could be axle wrap, bad springs, worn splines, bad carrier bearing, bad transmission, unbalanced shaft, or bad transfer case. IT WAS NONE OF THESE!! The issue is the slip yolk on the rear driveshaft, pure and simple. I tried Mobile 1, Moly fortified grease, AmsOil Performance 2000, various spray lubes including ones with Teflon and some with graphite. Nothing worked. Then I did some serious research on different greases and came across the DuPont Krytox. It worked. To use it, I had to clean the old grease out so I removed the shaft (follow Toyota’s directions), wiped, sprayed Gummout and either, and compressed air to remove the old crap. I did this procedure 5 times to completely clean to the bare steel. I put the Krytox directly on the splines and installed the shaft exactly as it was removed (very important). No bump or thump!! I just got back from a 3500 mile trip to Colorado and Utah with a lot of mountain driving and still no bump or thump. Krytox is pure magic! This stuff is amazing. It is very very expensive, but I was able to obtain a 2 oz. tube on ebay for $20. It was worth it!
