Default Rear Sway Bar Noise???

Hello guys-

Can anyone tell me what the sound of a rear sway bar would make if it was not lubricated or greased? I just picked up a 97 coupe that looks like the previous owner may have at least replaced the end links on the rear sway bar- perhaps the sway bar itself- it makes a clunk noise and somewhat of a grunt when you put it into a turn??? there is no tranny noise nor is there any whine from the rear (the car only has 40K miles on it) everything going in a straight line is quiet at any speed, seems like only when you turn at a lower speed do you hear it...

other then that- what a great machine...6 speed artic white with firethorn interior!!

left side:


Right Side:


end link: not plastic like early ones...

is there supposed to be something between the spring and that bolt? looks like a large gap to me...

Replace the rubber insulators on the sway bars. Its common for them to wear out and start making noise when it gets cold.

Make sure the endlinks are torque correctly

thanks- I will check both out...it also seems like the noise is there when I back up as well...I got out and physically rolled the rear tires forward and backward and I can hear a chatter or clicking sound??? it also makes this sound to some degree if the car bucks a little- you know like low RPM in a low gear...I hear the clicking...

the car only has 40K miles...about 4K miles a year over 10 years or so...sat for weeks at a time...I am thinking maybe I should replace the fluid in the rear as well...strange how it is only going slow or turning that makes the noise...

Going to the speed shop next week for a full checkup and diff change with Royal Purple...

Hi byte_me -

Yes - I would change the fluid in the diff - sounds like your diff is chattering based on your description of the noises.

Here is a link to a few pictures that I have that might help you when you change the fluid - I used Red Line gear oil in my diff - 2 quarts are needed.

May as well do the trans while you are at it....4 quarts of DEXRON III (I used Red Line ATF in mine....)

Also try a search on the rear axle splines for making noises. Cheap easy fix.

I agree on this.. the splines will cause a clicking type sound when first starting to move either forward or in reverse and it is in fact an easy fix.
