Car Vibrating , Mystery Puzzle

[chris26969]

My car vibrates at 50+ MPH . Plain and simple. It feels like it coming from the driver side front wheel. I have done the following recently and it happnd just around this time.

Did the Transfer Case Recall
2 Tie rods replace
Allignement
-Tires balanced

(today i rotated the front tire to the back and the back to the front to cancel out if the rim is bent. Yet it still does it).

What on earth could be wrong??

 

[Drifte]

Were your wheels balanced? i mean with weights. It could be they rotated your tires, and now its out of balance, maybe.

 

[chris26969]

Yep, Forogot to add that , a month ago the tires were balanced. (its been vibrating since August. I just cant stand it now.

It sounds like you did everything to rule out all other possibilities as you listed. The only thing I can think off is your either you have a loose half shaft bolt on one of the axle ends, I have seen that happen, or you have a bent hub. I would take an hour or so under your car and make sure all the suspension bolts are nice and tight just to rule that out.

Do your brakes act up when braking? Have you hit anything recently like a pot hole or curb with the car? Keep ruling out the possibilities as your doing and it will show up.

odd thing is. When I drive the vibrating happens 75% of the time after 50mph while sometimes it doesnt happen (25%) Then when i hit the brake today it made it worse. Just some more info to a complext mystery.

What about rotational direction of the tires. Are they unidirectional?

Wrong direction will do that.

How old are the tires?

 

[chris26969]

3 months old ....

Try checking for rolling direction if your tires are unidirectional... Also it may have something to do with lowering?

 

[chris26969]

my car is lowered. Yes. Hm. Could one of my shocks be done for? or coils? and just vibrating??

Also what if one of my rotors were bent to hell wouldnt that cause like problems ?? Like keep brushing up against the brakes. because my rims are chalked with brake dust all the time.

Did you check alignment AFTER lowering the car and replacing tie rods? Some shops do free alignment checks. (Like Firestone or PepBoys)

 

[chris26969]

car came Pre- Lowered. Thing was when i bought it with it lowered the car drove smooth at 80mph. It acted up right after the transfercase , bent tie rods , allignment. Im pondering if part of my suspesnion is shot and it could be bouncing around when i drive?

bad hub bearing?

 

[13secGST]

I've had the bolt that connects the lower control arm to the subframe come loose....and uhh well it was scary when I found out. Like Cablefed said, try checking ALL the bolts under there. Just to rule out that possiblity...because it is very possible.

 

[Defiant]

U-joint in the driveshaft is suspect, especially at that speed.

Check the tires closely for a sidewall blister.

 

[Black95TSIawd]

my car does the same and need a new u-joint. how much does it go for?

Fixed :

Took it to a place where I knew the guy and he told me that my rims were bent to hell. He bent them back. He also told me that my tires have never been balanced ( I have took them to another place numerous times) Turns out my usual shop decided they never watned to balance my tires every time i have asked them. WHILE still charging me.

Lesson of the day: WATCH your local shop and make sure they actually do the work on your car, rather than dropping it off and crossing your fingers.
