Car drives perfectly fine, until i get to 75mph i notice a slight vibration coming from the front end every couple seconds.. I just replaced tranny, axles, driver side wheel bearing, new drilled/slotted rotors w/ nice pads, new tie rods... An it still does it... I know I have some motor mount issues, but would that cause this specific problem maybe..??

many possibilities
-rims need to be balanced
-something is bent
-alignment is off

 

I chased a similar problem on my car.After replacing everything that you did plus a few others like having all my wheels checked, replacing tires checking rotor run-out ect. I found a bad lower ball joint. It tested good until you pushed up on the bottom of the tire it would then separate about 1/4".

is it constant or only under aceleration?
and your wheels are balanced?

 

bad axles can cause the car to wobble also

How long does the vibration last when it is doing it?

My first thoughts are that your rims+tires are not balanced... but fading in and out doesn't really match up.

 

Jack your car up, and put on jackstands, supporting the front of the vehicle. Now shake the tire and see what kinda of "woggy" you have! If it isn't any of the above mentioned things: then check these... INNER tie rod ends, Rack and Pinnion could be worn, Check strut rods aka radias rods, make sure ALL suspension nuts & bolts are tight. When you do all this report back. Mine had a similiar wobble but only in the excess of 70mph+ and it was inner tie rods. But I went ahead a replaced the whole rack and pinion with an ITR unit.

ight dude good ****.... i thought maybe rack an pinion but havent had time to get it up on jackstands i had to come to other coast for something thats how i found out that over 75 it shakes lol... im goin home tomorrow, ill do that an let u kno wassup preciate it..

 

if it was a bent wheel he would feel it at lower speeds. Higher speed vibrations are typically and most commonly caused by an unbalanced wheel, usually do to wheel weights falling off.

Take it to a tire shop and ensure that the wheels are properly balanced

it last for about 2 seconds, an happens about every 3 seconds... once under 75 it goes away...

 

did you replace all the stuff before or after the shake? maybe its one of the new parts you put in

 

check your ball joints

same thing happened to me

yeah im going to check those when i get home tomorrow i have a feeling that might be ight, because i remember while tightening my driver side LBJ it spun a little bit to much an i think i stripped it inside on accident "broken tq wrench " But yeah if thats the problem thats no biggie, i can do that in 10 minutes.. But as far as when did it occur, it just occured after i did new rotors an brakes...

 

a loose lug maybe?

 

Check:

1. Balance of wheels/tires (which will also rule out a bent rim.
2. Lug nuts
3. anything bent.

Well i got to checking an as far as Tire Kingdom says, my tires are balanced right an all my lug nuts are tight... And as far as my pesonal inspection nothing looks bent to me... Also I had another question... If it was the Rack an Pinion that had gone bad, wouldnt i be able to tell by delay in the wheel?? Like if i turn my wheel an it takes a second to turn isnt that how u tell if rack n pinion is bad?

 

flat spots in tires

 

bent rims
flat spot in tires or separation
warped brake rotors.
