I have had what sounds like the same problem as you with 2 Titans now. My first I traded in with the clunk still existing as nobody could find solution. Now second has been in shop 2 times without any success. The dealership installed the ProComp Stage 2 kit so they work on it under warranty. The first service trip they said it was normal. LOL Second time they at least acknowledged the fact it was not correct and worked on it. Report said they retorqued some body panel mount. Didnt sound right to me and sure enough clunk still exists. I also find my alignment only stays good for about 3 weeks of normal driving. Have you had this experience too. Not exactly sure where you explained the shavings are. Maybe a pic would be great and if I find anything out I will forward to you.

 

Another item I remember is it only appears to make the noise on droop, with no noise occuring on compression. Is this the same as yours.

 

The Upper Control Arm is hitting the "coilbucket". It's a poor design by Nissan.
Do you have a leveling kit of any sorts griff?? Reason I ask is most stock trucks don't have this issue, only trucks w/ a leveling or lift kit of some sorts. Normally the clunking sound is the shock itself "topping" out and at the same time destroying itself. Again, poor design by Nissan.

I have a leveling kit on mine and it seems youn could be right I never noticed it until after I put the kit on, I thought maybe I did something wrong. Is there any fix for this?

 

no i do not have any leveling kits the suspension is 100% stock. i do have a apt the nissan dealer thursday we will see what happens.here is a pic of it.

 

I have this also, sent an email to Greg asking if he knew a cure. No response in two weeks. He is a busy man though. I have the 1.25" on mine. I am not sure why you would be getting that on a completely bone stock front end.

 

My 08 does it bad, and it is not the control arm hitting the bucket, must be the shocks.

So, it typically only happens when someone mods their truck, but yet is still a "poor Nissan design"?

I've seen you write this a few times, and each time you write it you're as wrong as the time before. To claim that the shock is "destroying itself" by topping out is just silly and almost libelous. The shock is the limiting factor for suspension stroke on our trucks, thus it's designed to top out. That's why our shocks have stoppers in them that are separate from the valve assemblies. Ask Greg, I'm sure he's cut a few open in his time.

Do you have any data, anecdotal or otherwise, to demonstrate causality between top-out and the shock "destroys itself"? If not, I'd seriously consider not implying a truth where one cannot be proven.

Wow, 9 post? You must be a Nissan customer rep :upsidedow :upsidedow Mine did it before and after the mini-lift so I don't contribute it to the lift at all. It only does it on the drop. There have been people that replaced with higher quality shocks and it went away.

:cheers:

Content, not postcount, my friend. Been lurking here for years.

Implying that the replacement shocks are "higher quality" is a fallacy. People replace the shocks with units that have different characteristics and configurations than the stock units, and the noise stops. Doesn't mean that the replacement units are of higher quality, just means that they're different.

 

So are you saying that there are no shocks that are higher quality than others?

No. All I'm stating is that a replacement unit is not necessarily of higher quality if it has less topping noise. It just means that the shock is different in some way that eliminates the noise, such as stopper configuration, damping rates, extended length, etc.

 

Mine is bone stock and has done it since new. Went to dealer 3 times and all they did was waste my time. One problem solver is a set of bilstiens 5100 or 5150 series shocks.

 

I have had mine to the dealership 2 times to have this looked at. I have to admit the service people are taking great care and concern with my vehicle as they have a close interest in it as it is free advertisement for them as it is one of few 08 CC LWB with the lift kit in this area. Anyways, this last trip they feel it has to do with the cab mounts that are a potential cause for this clunk noise. They actually lifted the entire cab off the frame enough for them to replace the rubber bushings as they feel they fail prematurely in our winter climates. I have to admit it has made a difference but would like to wait for 1 month before I consider it cured. Another note, my windshield developed a crack about 14" from the bottom on the passenger side and they are replacing it under warranty. They have found a number of 08 CC are having this problem, but only with the long box. Perhaps this has happened to others and they can get some new glass.

 

my 08 does this also and i'm pretty sure it's the uca hitt'n the coilbucket. i'm planning to get PRGs uppers and SAW coilovers to correct the clunk.i have no lift at this time..

 

Mine does it - has since I put the leveling kit on it.

The fix is simple and well known. It's called a grinder. Grind a relief in the coil bucket - it's not structural (as long as you don't get too carried away)...

Hmm, then why all the owners with STOCK trucks chiming in with problems

Yes, I'd say he has: http://www.titantalk.com/forums/739858-post6.html

also:

On the 08's you need to grind a little bit on the drivers side coil bucket. It seems as though Nissan has the frames built on a new jig and there is a small clearance issue now (the coilbuket is welded a bit higher on the frame now).

Do you have any data, anecdotal or otherwise, to demonstrate causality between top-out and the shock "destroys itself"? If not, I'd seriously consider not implying a truth where one cannot be proven.

See my comments in red. What crawled up your ***?

Some line of thought would be you need to read more and continue to post less. You are dipping into an area which you seem to have no personal experience. I have had TWO Titans. one 2wd and one 4wd. Both have had this issue. The 2wd stayed stock, and the 4wd has the level only. UCA bucket wearing a hole in itself do to striking the coil bucket is Piss Poor Design and a very well know issue. Not Operator error. Simple fix has been to either grind away safely, or replace crappy stock shocks with a quality name brand.

People replace the shocks with units that have different characteristics and configurations than the stock units, and the noise stops. Doesn't mean that the replacement units are of higher quality, just means that they're different.

Everyone say hello to the 800 Nissan Customer Support guy.

This is more crap from the fountain jr. POST LESS READ MORE... Try back in a year.

 

I have a 6'' fabtech suspension lift and the rancho all in one leveling kit/shocks and when i go over bumps my front end makes noise like the shocks are bottoming out or the lift is bangging against the frame im reall clueless to what is causing this !!

 

It could be coil bucket contact. You might need some aftermarket ucas

Yeah everyone i asked about it told me that i probably need to replace my upper control arm bushings the problem is i cant find any place that sells the bushing kits..any suggestions ??

Don't just start replacing parts because guys told you "it is probably part x". Find the part that is causing the issue and fix it. If you don't know what to look for, then you should probably take the truck to someone who does. Anyway, I posted a few suggestions of where to start in your other thread about this issue.

 

Just bought my '11 a month and a half ago, and i noticed the clunk too. It does it during compression of the shocks. If i go over a good speed bump, i get 2 clunks, 1 on initial compression from the bump, and the 2nd on compression from the drop after the bump. I will discuss it with Nissan when it goes in for its 1st service in a week or two.

 

My 2010 has had the same noise when going over bumps or pot holes since day one. Plus crappy tire wear,bed thats on crooked,big lump right in the middle of the driver side seat cushion that feels like a rock, hvac actuator motor bad, whats next? Im tired of bringing into the dealer,and being without my truck that i use to work with every day. Love the trucknbut damm!

 

Our '05 only started this when we put the Pro Comp lift on it. We went with the stage II lift and were warned by the installer that it was the shock topping out...

 

You have coilovers? If so, need to remember that there is no rubber bushings, etc on the coilover shocks like the stock shocks and bilstiens have. The rubber is dampening the noise. Coilovers are allowing the noise to travel from the LCA straight to the UCB.

 

My '08 SE with stock suspension had the clunk on rebound, getting worse and worse after 30,000 miles, and a switch to Bilstein shocks with actual rebound damping at 40,000 miles eliminated the problem. At 95,000 now, with no problem since the shock switch. My '04, which had better OE shocks, did not have the problem over 90,000 miles, but if you remember on the '08 model you had to buy the Pro-4X to get what was at least partially stock on the '04.
