A dealer should be able to fix the vibration if it is the driveshaft. If it's the tires they might cover it but the tires have a seperate warranty.
I noticed my passenger seat shakes a little bit at hwy speeds but I didn't think it was anything because the seat is the only indication of the shake. I'm interested in finding out what info you get on this.adkl1 said:hi im a new 08 pro-4x owner.. love the truck but i have a few problems to get worked out. I flew up to SAN FRAN to pick this truck up and drove it home to the PHX area had a great time driving down the coast but when i got to the LA area i noticed i had a side to side vib it starts around 65mph and stops around 76mph. i dont feel it in the steering wheel but it shakes the seats so i stopped at a tire shop and had the front two tires road forced balanced (watched the tech) got them back to spec. so i continued home well i was going of a overpass BAM DEATH WOBBLE i knew what was going on so i slowed down and got it under control then it happened 3 more times.. So i got off the concrete freeway onto asphalt and set the speed at 71mph and was getting that shaking all the way until i got to AZ and was able to bump the speed up to 81mph BAM no more shaking.. so anyways does anybody have any info i can give the dealer so they can fix the problem ???? Could the drive shaft not be balanced right ?? please help it will drive me crazy...
I have that same exact "combination" (Rancho shocks, and even wider tires than the PRO4X) on my 04 SE. It came as the OR package before the 08 models. Where do you get your information?...lol.eagle sg said:The Pro4X package combines heavier shocks and more agressive tire size and tread. Seems to me that the combination was not extensively tested before release. Go see your dealer (be nice) and ask them to call tech support, they are aware of the situation, however they said to be working on a solution.
Don't call the 800 number as the "out of country" operator can not help you.
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.eagle sg said:The shocks are not "blown". and the pre 08 shocks are not necessarily the same valving. The "wobble" seems to be more pronounced in the longer wheelbase configurations.
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.eagle sg said: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.
