I have a 07 f150 and while driving I have a vibration only in 4wheel drive high but not a bad one but when I take my foot off the throttle it gets worse as well as a rumbling sound!! this is only after a 6" lift was installed it seems and I have replaced both front drive shaft u joints thinking that was the problem but didn't solve the problem....
View 2 RepliesNew to my 2008 GX470. 100k miles. Love it so far. However I think I am hearing a intermittent rumbling as I drive down the road. It is like the rumble from a radio base sound. It could be normal road noise but I bet it is not.
I have replaced the left front axle (grease boot broken), replaced the rotors and pads, replaced all differential and transfer case fluids (not transmission yet) and inspected all the suspension parts.
I recently replaced the oil seal on the front differential where the front drive shaft connects to the diff. I believe it is called the pinion oil seal. I had to remove the drive shaft to do the job. Got the oil seal in place and then slipped the u-joint yoke on and hand threaded the retainer nut on to get it started. I did mark the relative position of the drive shaft to the front yoke and the rear yoke. I had previously noted that the retaining nut, before I took it off had about 2.5 threads showing. I had to remove it with an impact wrench.
So...I used the impact wrench to put it back on with about the same number of threads showing. I then reinstalled the little short fronmt drive shaft...the one that comes out of the transfer case. I got the front of it on to the pinion output on the front diff...and then had to reattach it to the transfer case end which, by the way an interesting affair with a sort of metal cone that is attached by 6 8mm fine threaded bolts about 2.5 or 3 inches long. Got all that done with much grunting an groaning - I'm laying on the ground - SO the oil, leak is fixed but now ...
There is a vibration at around 40 mph and higher. like something is out of balance. did i damage the front diff pinion bearing by using an impact wrench? this vibration occurs in 2 wheel drive. as i understand it the front drive shaft doesn't even turn when in 2 wheel drive. my question is does the front diff gears spin when in 2 wheel drive? perhaps the u-joint is bad on the front drive shaft? just a bit baffled. when the speed drops to below 40mph the vibration goes away...
My 2006 RAV4 Sport 4WD, 80K miles, is making a light rumbling or light vibration noise as I drive down the road. It's intermittent, and will generally stop making the noise when I let off the gas (auto trans). It happens at different speeds and will always quit if I let off the accelerator, but doesn't always quit if I step on it. It's just faint enough I can tell it's there, and doesn't sound or feel very severe. I probably would never notice it if my stereo was on. I thought it might be my Bridgestone tires, which have less than 10K miles on them, but I would think the noise would continue even if I let off on gas.
View 3 Replies2007 XLS Crew Cab 2wd. 60K miles When going through the 35 to 60 mile per hour range there is a vibration that seems to come from the drive shaft. Let off the gas and it goes away. After 60 mph it seems to be gone. I am thinking Trans support, motor support? One of the postings on this sight made me wonder about the transmission. By the way, I just bought this truck used and love it. Can I run flex fuel in the 4.6L engine?
View 1 RepliesI have read through the folders and many websites on 4x4 problems. My problem has to deal with my four wheel drive not wanting to engage. It has nothing to do with the front end or solenoids. When I put it into 4x4, hi or low it will not send any power to my transfer case motor. It wont even illuminate any lights on the selector switch. I have checked all fuses and replaced any relays that have to do with the 4x4. Where I should go with this?
View 7 RepliesI have a 2006 F150 4x4 5.4L 43000mi. My four wheel drive is not working. I have the dash mounted switch to switch it into 4x4 Hi 4x4 Low. When I put the switch into 4x4 Hi nothing happens. 4x4 does not engage, and the 4x4 Hi light on the dash does not illuminate. I get the same symptom when the switch is placed into 4x4 Low. I have checked all of the 4x4 fuses and they are ok. I checked all of the vacuum lines to the hubs and they appear to be intact. What I should check next? What would cause this?
View 14 RepliesI have a 2005 F-150 with ESOF. When I turn the switch to 4x4 or 4low the lights on the dash will turn on but the front tires will not turn. I checked all the fuses and they were good. I'm not very familiar with this 4x4 system, what the issue is or on how to fix it?

View 6 RepliesI hit a curb while making too sharp of a right hand turn a week ago and now I notice some vibration in the steering wheel as I drive down the highway. The tire I hit was the rear passenger side. If I get wheel balancing done, do I need to just balance that tire or all of them?
View 3 RepliesI made a big mistake, I was cleaning out my truck and accidentally switched my 4 wheel drive to the 4 low position. Not knowing this I started the truck and just drove it all day. Then I noticed my mistake and now the truck will not shift into either 4 high or 4 low!
The truck drives just fine, I feel no pull when I turn to the left or right so it seems that it never did any shifting into 4 high or 4 low, so I'm looking for recommendations on maybe how to fix?
(2004 f150 S.Crew 4x4) I noticed that my 4 wheel drive is not working. The front hubs won't lock in. The transfer case will go into 4 low but the hubs still won't lock in.
Anyway, I have pulled vacuum on both actuators and one of them won't hold. It's obviously bad, but is that why I don't have 4x4? It seems to me like it is not...
When I pull a vacuum on the actuator that does hold, it disengages the hub from the driveshaft allowing free-wheeling. Correct me if I'm wrong, but when the truck is running in 2wd, vacuum must flow to the actuators preventing the hubs from engaging? The actuator on the bad side is locked 'in' so the driveshaft always turns.
According to my train of thought, since the actuator has failed in the 'locked in' position, I should still have 4x4- What am I missing?
It feels like I am having a front bearing issue, when turning the steering wheel to the right I feel a slight vibration in the steering, need to know which one is going out,??? I have already replaced the passenger side twice It just seems to not tighten completely as I can still move the tire slightly while up on a jack...
View 12 RepliesOk, So, Im 40 miles from home stuck in ice and snow in a hotel.. (my wife works close by- thought it would be safer than driving in the 10 inches of snow we got 3 days in a row) so, I go to pick her up tonight and I engage 4hi.. I hear the click and the light comes on.. but no clunk of the hubs locking.. I drop it in 4 lo.. it shifts in low.. but the hubs are not locking..
I hear a ticking sound as I drive and when I put it in 2wd it goes away. I turn off the truck, turn the wheel hard both ways .. get out and I can physically turn the drive shaft and I hear the ticking in the hubs. If I read correctly when the truck is off these should be locked?
is it possible the vacuum is not releasing? I also get the groaning when I start up of the air diverter.. that im told is operated by vacuum.. so I am guessing I have a vacuum problem??
My car is 7k short of its drive train warranty expiring. I noticed a rumbling vibration when the transmission shifted between 3-4 gear at approximately 20-25 mph. Took it into the dealer, and their expert rode with me and verified that it indeed was vibrating, but that he had never seen this issue on the 2007 GS350 AWD. He said he would have to check around the country to see if others had this problem. Four days later, he advised me that he was told to flush the transmission 2-3 times and for me to drive it about 1k miles to see if that fixed it. Well, it doesn't do it anymore, but I'm not sure why, or that it won't do it again just after the warranty expires at 70k miles. I certainly don't want to look at a 4-6,000.00 transmission replacement after the warranty expires. The dealer obviously doesn't want to incur the expense either, under warranty. Even though the transmission does not rumble or vibrate anymore, should I ask for the replacement anyway?
View 6 RepliesI purchased a used LS 460L w/ 60k miles after a few months noticed a rumbling sound front end noise took it to dealer was told upper and lower control arms and bushings needed to be replaced at a cost of $4,000. Looking for options have a friend with LS460 w/90k miles no problems must be the L version issue ???
View 1 Replies2008 2wd 4.6L 98K miles F150 for the past few weeks has been humming with a rhythmic vibration which feels like it is coming from driver's side front wheel. It doesn't do it constantly, nor at all speeds. Once I hit about 25mph, you can start to hear a humming. At 35, slight vibration. Between 50-60, heavier vibration. Sometimes at 65+, it subsides quite a bit. Both front rotor assemblies are newer, and I put in a brand new left because I thought it was a bad bearing.

View 1 RepliesIn my 2006 Prius, I just started noticing this recently, but whenever I turn my steering wheel, it makes a weird noise and I can feel something going on through the steering wheel. It doesn't impede my steering, the car steers just fine... It's just an add sound, I don't want to say a cracking sound... but it kind of is? I don't know. I'll have to put a video of it up. & it doesn't matter which way I turn it, it still makes the weird sound and the intermittent vibration... I know it has E-steering and occasionally you can here the motor whirring when you turn it but this is different, it's a loud... popping noise is the word for it! Popping, and I can feel it when it pops through the steering wheel. Again, it doesn't impede the steering ability at all, but something isn't right I'm sure... Or maybe it's normal.

View 7 RepliesMy 2008 F-150 recently started making a funny noise from what seems like the front right wheel.
The weird thing is that it will only make the noise while accelerating. The second i take my foot off the it stops. Also, the sound stops if i put it into 4WD and does not happen at all in 4WD.
It has nothing to do with turning or breaking. It only makes the sound in 2WD while my foot is on the gas.
The sound is kind of weird. It sounds like something is loose, and it sounds similar to tin vibrating on metal.
At first i thought it may have been heat shielding rubbing on something, I checked under the truck and found nothing loose.
It's weird that it only happen in 2wd yet in the front end.
Someone had mentioned that it may have something to do with the fact that there is no torque on the front wheels in 2wd and when i put it into 4wd it put torque on it, whatever might be loose then becomes tight.
