Need help with DW, spark plugs, and accessories for '06 wrangler

Hey there! I'm a "newbie" and desperately need some help!! I recently purchased a 2006 Wrangler 4.0 in May with 42,000 miles. I am having a few issues...

1. What exactly is Death Wiggle?? My TJ drives like a Mack Truck!! We have replaced the tires, had an alignment, and replaced the steering dampner. Although it has improved a little still drives pretty rough. I also feel some clicking and popping in the steering wheel when I turn or hit bumps.

2. We recently gave our Wrangler a tune up because our gas mileage was HORRIBLE! We replaced the old spark plugs (which were not even close to being gapped correctly...hence the gas mileage I suppose) and replaced them Autolite Platinums. Since then, the gas mileage has improved but it bogs down at about 45 mph and has no get up an go. We rechecked the spark plugs and boots and everything was good. Any advice? Does one plug run better than the other in a Jeep (this is my first)? Maybe Autolite Double Plats or Bosch Double Plats?

3. We would like to start outfitting our Jeep with some awesome accessories like lights, nerf bars, SS bumper, etc. Does anyone recommend a place to purchase anything like this??

Thanks so much for the time and thought in responses. This territory is new to us so we want to make sure we do whatever we do the right way!! We love our Jeep Jeep (as our 3yr old daughter calls it) and are really glad we purchased it. It's like an addiction...

I would replace with whatever plug was OEM. My 04 OEM are NGK ZFR5N. Your 06 could be different.

1. For your DW, what your describing really does not sound like DW. DW would be uncontrolable shaking of the front end where you can not control the steering our the shaking. Search youtube and you'll get an idea.

The clicking / popping is probably a u-joint or possibly bad ball joints. To check for bad Ball Joints, jack up the front end and then grabbing front tires at top & bottom, try pushing & pulling while watching Ball Joints to see if theres excessive play.

For checking the u-joints you should be able to check by look and by grasping the axle u-joint by the wheel and rotate / pushing to see if theres play.

2. Plugs I would also say OEM or the NGK plugs. The 4.0 is not a performance engine so no need for the hgh end plugs like Bosch, since typically burn hotter for a performance engine.

First welcome to the Forum from another Georgian.

Okay. Death Wobble: You will know it when you experience it. Nothing quite like it. Scary as H---.

I drive an 06 4.0 Unlimited and I didn't buy it for mpg. I'm lucky to get 12 in the city and 15 on the highway. I didn't see anything about your rig in your profile. Is it standard or auto? I have an automatic and there is an o/d off toggle. If you are experiencing the "bogging down" effect in city driving, try switching off the o/d and see if that helps. Mine tends to want to shift into o/d a little too early IMO.

As far as the popping sound, I would start with the advice already given. I had those issues, but it seemed to go away with new rubber and as you have already replaced your tires I can't add anything further.

Yes, not all plugs are created equal.

Look at your underhood sticker - it tells you what plugs to use - it even gives you a choice.

The kids at the parts house know more than the engineers that designed it?
It's no wonder the country is falling apart - stupidity abounds!

Thanks so very much for your have all given me great info!! Under the hood it does request NGK spark plugs but the Jeep Dealership said to use I guess it's back to NGK we go...LOL! We'll check the u joints/ball joints...I'm sure they need to be replaced..better to be safe than sorry. Thank Goodness I don't seem to have DW...I was hoping it wasn't that...just some maintenance stuff to replace...whew!! I'm going right now Quadratec....I'll probably go wild on that website...LOL!

Your local autostore should be able to carry the U-joints & Ball Joints cheaper then Quadratec.

For u-joints I recommend either Spicers or the Napa Precision

For Ball Joints Moog or TRW

With only having 42k miles I'm willing to guess it's the u-joints. Also replace both Driver & Passenger side u-joints, not just the one thats bad. Your better off with two new ones.
