hey guys, today i was driving home from work on the highway ike i have been the past week and a half with the lift but today i realized once i got over 45MPH i could feel just a slight vibration, at first i figured it was the tires but i really have never felt it before and i've drivin on the highway a good amount since the lift. then as cars drove past me i could hear a slight noise it seemed to be coming from the drivers side, i cant really explain what the noise was, it was very faint but i could tell it was there, like if you drive off to the shoulder on the highway some shoulders have the washboard like dips on the side to warn you if your going off to the shoulder, if was kind of a sound like that but very quiet.

Maybe im just being paranoid but the ride felt different today than it did 2 days ago on the highway.

Any suggestions?

 

have you had the e-brake on recently?

 

nope

 

My dad's 04 is doing the same thing. Here is what we are investigating as causes.

1) Wheel Bearing
2) Tires
3) Brakes

If you have a set of tires, swap those first or swap front to rear. The wheel bearing is easy enough to replace. Note that the spindle nut says to use only once. I've never seen that before.
Warped rotors can cause a vibration.

 

you didnt really lift it big enough to need new drivelines, but maybe its the driveshaft out of balance or something?

 

Hey guys well i looked at it this morning, i noticed some grease On the control arm coming from either the hub assembly or the cv Joint. im Hope its the hub. the grease had some metal shavings it in so something is getting Messed up.

 

Alright i seen that the CV boot is slit at the outter boot ( towards the wheel) and the grease is coming from there.

Now does anyone now if its alright to drive around with it like that? I mean i know i will need a new CV im going to buy one but for the next two days will it be okay if i drive through the streets (no highway). It wont lock up or anything will it?

 

It shouldnt be spinning unless you're in 4x4 so should be alright, someone correct me if im wrong... but I'm almost positive it doesnt spin, if it does Im pretty sure theres something wrong

 

You will be 100% fine with 4x2 highway and city driving. The front axle/driveshaft/halfshafts/cv joints DO NOT SPIN WHILE IN 4X4 (sorry, just wanted to make sure there is no confusion...a few guys on this site believe otherwise)


just stay out of 4x4 until you can get a new cv joint and boot

 

although...if you have a bad IWE...it could be spinning that cv joint and that is what caused the problem in the first place.


mark your halfshaft and front driveshaft with chalk or marker. then drive in 4x2 a few hundred feet and inspect. hopefully the halfshaft and driveshaft are in the same place

 

Iwe?

 

Vacuum solenoids to actuate hubs to make cvs turn the wheels as far as I know

 

the new auto hub is called an IWE (Integrated Wheel End). It operates off of a vacuum

motor on, switch in 4x2 = 4x2 drive
motor on, switch in 4x4 = 4x4 drive
motor off = front hubs engaged

with motor running, a vacuum pump on firewall draws a vacuum and disengages the IWE hubs. if these vacuum lines are bad, or the vacuum motor is bad, it can make your hubs engage while you drive down the road...and then the hubs fail

 

To add to Tylus's info. If the vacuum to the IWE drops out while driving, you will experience some nasty noises. But if your vacuum system drops out before you start rolling, you may not be aware of the issue. But you might experience resistance or binding from the front, just like you would when 4 wheel drive is engaged and your on a high fricture surface.

 

damn thanks alot guys! i appreciate all the answers!!
