My son has a 2002 Cavalier.
Recently he has been hearing at speeds over about 25 a loud sound which
sounds like its in front of the driver in engine area. Its sort of a deep
roaring which gets louder as you drive faster.
No sound slowly. I tried to shift the gears to see if it changed and it
really didn't. At low gear you don't hear it much cause I think your not
going fast enough but as you put the car in Second or third gear and speed
up it begins. (car is automatic)
Any thoughts ?
Usually if it's a hub you will hear the tone and level of the noise
change when going through turns. This is due to the weight transfer
loading and unloading the bearings inside the hub.
For instance if the noise increases when you are turning to the right.
then it is probably the left (drivers side) hub.
If you hear it more while turning left then it is likely the right
I have replaced a LOT of hubs that made serious noise but when you
rolled them over by hand you didn't feel any vibration or roughness.
The turns I am referring to are ones where your at 30-40 mph and go
around a sweeping bend in the road. NOT doing circles in a parking lot
at low speed.
I wanted to get back to group.
So I replaced the hub on the front left. As people suggested here. Sound
went away and it solved my problem. The only hangup I had was that when I
got to the hub it required a Torqs bit. You know one of those ones that are
star like. Which I didnt have so I had to buy a set. Grrr . Are car
manufacturers actually owned by tool manufacerters? However on the good side
the torqs bolts were accesseable from the front so that ment no fiddling
with it from behind. You just had to turn the hub so that you lined up a
hole on the hub with the bold to get the socket through. Anyway just wanted
to say thanks. Fairly easy job really, once you have the tools (1/2 inch
socket and big pipe) and know how.
Had something like that happen on an earlier model, starts at a low
vibration at hiways speeds. Turned out to be very pricy when I got the
estimate. Universal joints messed up and vibration or whatever didn't
stop there. Hubs, upper, lower...a mess. Even tires were showing the
start of abnormal wear. Since it was just starting, I drove it for a
week or so until I got a new vehicle from a different manufacturer and
then sold it for parts/as is. Even noted it on the bill of sale as to
Socialism and statism are great as long as someone else pays for it.
