well my car is making a sort of rough noise. kinda like a truck with big tires on them going fast down the freeway. i know the hubs on these cars suck, and stock perilles suck as well.

well the faster i go the louder the noise gets, doesn't change if i swerve side to side. and i cant tell what it is from. it is a 06 LSJ with 54k on it. tires are pretty crappy but not gone completely.

is there a way i can tell what the problem is?

 

Jack the car up and try to wiggle the tires side to side. If they have play in them, the hubs are probably shot.

 

tried that, didnt feel any play other then both moving. just got new tires put on and still making the noise and i can feel it now in the peddles almost like a grinding now.

 

its one of the bearings most likely. i was going to suggest roatating the tires but you already got new ones.

it doesnt get quieter when you turn one way or the other?

 

lol dealer tells me its my new tires, or my slotted rotors. hope you dont have those

 

In for an answer. Same problem with my 2005 LSJ

 

not that i can tell, all started the other day hit a nasty pot hole in a construction zone. and notice no change with noise except with speed, turning does not make a difference.


i do have drilled and slotted rotors, no problems with brakes tho,

 

just called pepboys, there going to diagnose it for me for 20 bucks. and of course they dont have it in stock
let ya know what it is when i find out

 

Just talked to pep boys. Said wheel bearing for sure but also noise from transmission. Wtf

 

if the noise goes with road speed and doesnt change when you swerve left to right, doesnt change on and off the throttle (accel to decel) or doesnt change when you push the clutch in, its tires. wheel bearings, even if both are bad, will have some sort of change in pitch or volume when swerving. constant noise like you are describing is tires.

i had an expedition in my shop last week with the same thing, noise with road speed. another shop changed all 4 wheel hubs, noise was still the same. i sent him for a new set of tires (they were down to wear bars anyways). couple hours later he was back to let us know the tires fixed the noise.

 

had tires replaced today. still noise, car is at shop now, machinac said driver front side wheel bearing was bad and there was also something going on in the transmission. but not sure if he knew anything about lsd trans.
