08 with death wobble & vib - Page 2

**anmut** · 12-03-2007, 01:27 PM

Yep - if it was a wobble in the drive shaft at highway speeds we would see them breaking apart or doing other significant damage. I think there's a TSB for the front ball joints - could that be related?

The Ranchos on the new 2008 Nissan Titan PRO4X are the exact same ones Nissan has used since 2004. A valving change from year to year, however slight, isn't going to cause the problems mentioned....c'mon already! It has to be something revolving.....tire, wheel or driveshaft. Sure the LWB would wobble more, more/longer unbalanced driveshaft?....more wobble. Show us where Nissan is aware and is looking for a cure to this problem....because I find nothing about it.

Actually, they are not the same and they are not the same part number. Just because your dealership has nothing in writing from nissan does not mean we haven't done the legwork already. I am not posting pure speculation. Here is a tip. Take a pro4 that has the condition in question verified. Swap the shocks and wheels out of an LE, put the pro4 wheels back on and you shall get your result.(Not very likely, as at most dealers the tech will not get paid since nissan does not pay) Nissan notoriously does not propagate any information regarding fixes from dealer to dealer. Many times they will deny any knowledge of having a record on whatever you are calling about only to find out later that they could have told you what was wrong in the first place and save you an afternoon chasing a problem for which the technician may not get paid. All it means that my crew is on the ball and yours is not in this case. Which in reality turns out to be irrelevant because under warranty you can not install different parts unless otherwise authorized or noted by a TSB.
Sorry for the endless sentence,gotta go Pats are on.

If it's the shocks, why change the wheels also? There's nothing a shock does that would cause the truck to vibrate. A broken shock would cause a bounce but...lol...not the vibration mentioned here. Now a bad wheel and/or tire? certainly. So if your changing out the shocks AND the wheels fixed it, the shocks probably weren't the culprit.

I know it was a long sentence, but if you read it again you will see. Your statement is technically incorrect. Its a matter of parts of the vehicle not working correctly together or set up problem if you will rather than bad parts.If it was a bad wheel or axle shaft it would have been resolved within an hour or so on the first visit without getting tech involved.

eagle sg: Your posts contradict themselves and the way you state them make it very hard for us (well for me actually), to understand what you area really saying. It make's it seam like you are just trolling this thread and trying to provide FUD, but I would like to give you the benefit of the doubt. I am a new member of this forum as well but it would seam as if you want to portray yourself as someone who has inside knowledge as to what is going on here directly with Nissan. If that was your intention, great, please elaborate. If not then please clarify as to what your personal observations are. So here it goes, please start from a clean slate in terms of your explanation:

What would you do personally to resolve the Original Poster's problem with his wobble on a 2008 Nissan Titan Pro4X? And how would that change to his setup resolve this issue in his Titan and possibly others?

54warrior · 12-04-2007, 12:19 PM

Rich, I think that part of the reason many are skeptical of your statements/opinion is because you have a grand total of nine posts and come on here basically proclaiming to know exactly what the problem is. Not trying to question your knowledge/ability, but maybe some background information on what you do, why you claim to know so much about these trucks would be helpful, informative, and might in fact give us reason to believe you!!

Heavier shocks??? Please explain that one to me. The OR and Non-OR trucks have the same coilover springs on the front, only the shock itself is different (Rancho Offroad shock vs. factory shock). The springs (which are the same) handle the weight of the truck, the shock just absorbs the energy that is stored in the spring.

I agree with that assessment, in that order, chances are that it's a bad tire, if not, then a bad wheel, and a slight possibility that it's the DS.

Ok, well instead of simply "you will get your result", how about an explanation, please??? The way I interperet it is that the shocks were the problem, but you didn't really come right out and say that, instead you went on blabbering about Nissan's procedures, yadda yadda yaddd...

which doesn't really do us any good in helping resolve the issue at hand! We could all really care less about that fact.

I agree.

Ok, so based on that theory, EVERY SINGLE 2008 PRO 4X LWB Titan should be experiencing this problem!

Had my reply all done, got called away and lost it. What is FUD ?
If the little mentions on nissans policies is jabber then ignore those lines and if ones experience is measured by the number of posts i'll promise to post more often.

Troll? I have three master rings that suggest otherwise. I appologize if the post are confusing to some, not my intention.

Eagle, Come on now, this is really starting to get old. You've been asked straight out and have done nothing but dance around anything resembling an answer. So I have to call BS on your "knowledge" based on what we've seen your write here. If I'm wrong....I'm sorry ...so, I'll simply ask again:

Exactly WHAT is it that's causing the vibration, specific to the PRO4X, that Nissan is somehow aware of ? Please don't give a runaround answer explaining what it COULD be....we can do that ourselves.
Please explain just how a shock...ANY shock, can cause a vibration. Pretty simple question...to someone cliaming to have the answer that is. We're all lost.

eagle sg · 12-04-2007, 02:45 PM

Who is WE? You mean, you are lost and need step by step instructions?
If the valving in a specific shock setup is too stiff within 10% of the center or rest position it will transfer the oscillation of the wheel/tire assembly into the frame. Tire and wheel packages are not necessarily perfectly round even when road forced and balanced. By process of elimination this can be verified on the vehicle in question. The same truck with the standard set up does not exhibit the "wobble".

As to the tech line. They will deny any knowledge until the engineering department catches up with the real world. Then again, they don't have to deal wit the customer that wants his new bay fixed, NOW.

"WE" meaning...everyone here who's basically said the same thing to you! You may want to look at all the posts here. You talk in circles, making yourself look like the typical "I'm a Nissan tech" poser we've seen here time and time again.

"If the valving in a specific shock setup is too stiff within 10% of the center or rest position it will transfer the oscillation of the wheel/tire assembly into the frame. Tire and wheel packages are not necessarily perfectly round even when road forced and balanced."

What an absolute compilation of twisted garbage! Do people where you're from actually buy your line of unfactual BS? Call it what it is...It;s the wheel/tire setup or driveshaft issue! That's been said all along. It has NOTHING to do with the shocks. Nothing a shock can do will cause the vibration mentioned. Wheel hop from bad shocks is entirely different. There's nothing NEW on the 08 that should be a problem, other than the wheels/tires. The rest are all carryover parts!

if the oscillation of the wheel/tire assembly is being transfered to the frame, then the wheel/tire assy. is the problem... a balanced wheel tire will not have any amount of signifigant oscillation.

the 08 pro-4x is the same thing as the 04-07 off-road package, with the exception of the 08 having some interior differences.

a shock, if it is doing what it is supposed to, will transfer some of the "bad vibes" to the vehilce via the frame.

i do notice that my 07 OR titan is significantly stiffer on the smaller bumps on the highway, but performs much better on gravel roads and off-road than my 2006 non-OR titan...

so in conclusion i believe you are FOS and the tire/wheel is a problem... not like a tire has never been bad...
