vibration on dry pavement
 
Hello,
I just got an 08 unlimited. Thing is, it is my first Jeep and I'm not sure if my 'problem' is normal or not. When I'm on dry pavement I notice a vibration in the steering wheel (2 wheel drive). It's not a bump vibration or anything, just a hum, if you can imagine that, with an almost in-audible whine. I'm not sure if that is just how jeeps are or what. The guy we bought it from said that it is just the road, but it just doesn't feel right to me (or I'm not used to it). I've researched the problem and all I've found is vibration with 4 wheel drive on dry pavement. Any suggestions?
Thanks

the first thing i would do is rotate the tires and see if the noise changes. could just be tire noise. obviously check for worn tires.

what kind of tires are on it? some people who aare not used to driving w/ all terrain or mud terrain tires think there is a problem, when it's only the tires on the road.

Also, more info would help diagnose.

Is it constant or intermittent?

Does it increase in severity with increased speed?

Does it only happen at a certain speed?

As posted previously, AT's & MT's do generate more road noise (hum) than "street tires".

Inermittent vibrations could be a worn or inadequate steering stabilizer while constant vibs could be tire balance or other worn steering components.

Either way, more info would be helpful.

I've got BFG wrangler tires on it (regular), no all terrain or anything. The vibration is mostly noticable around 15 - 30 mph and is less severe the faster I go.

Rebalance the tires, check the alignment. If this has no effect then you could have a bad tire.

Don't most jeeps come with all terrain tires on them? I got mud tires stock because it is a Rubicon. I would agree about balancing the tires with vibration at 15 to 30. How many miles on the tires? New tires could be defective. Old tires could have problems just by how they have been treated. A separated belt for instance. I'm not an expert on this though. A tire place could probably identify the problem if they are good at what they do.

Did say it was a 2x4, so I would guess "P" series radial tires.... Not knowing how many miles on it, but being an 08 would assume somewhat low, I would be sure ballance weights are still on, lug nuts tight

since this guy only posted a couple times on one day over a month ago, and the fact that he has "bfg wrangler" tires, i don't think he's coming back to tell us about his tires being the problem. he just had a noisey tire, how did we get into balance and alilgnment for a tire hum?

Must have had too much to drink... didnt notice it as an old post

If you have read the whole thread, you would have noticed that even though the original post was a month old, the poster has responded to questions so it is not like he posted and abandoned the thread.

Even if he did abandon the thread, does that justify insulting him by calling him a loser? Most posts on this forum have been downright friendly, that is why people like the place. Some of the posts are a little rough but usually said with sarcasm, that is understandable. Outright insults...now that is questionable on a friendly forum. You may not like some other poster's behavior and that is OK but you can say that you don't like the behavior without resorting to name calling. It just stinks up the place. Just my opinion.
