Rear Suspension - Squeak/Rubbing Noise
No.: TSB-99-34-001
DATE: February, 1999
MODEL: See Below
SUBJECT:
ABNORMAL NOISES FROM REAR SUSPENSION
This bulletin supersedes TSB-98-34-001 dated May, 1998, which should be discarded. New and/or revised information marked by **.
PURPOSE
This bulletin has procedures for repairing abnormal noises from the rear suspension on certain 1995-99 Eclipse and 1996-99 Eclipse Spyder.
BACKGROUND INFORMATION
Symptom
The customer may complain of a squeaking, a hard rubbing noise, and/or a light tapping or knocking sound from the rear suspension when driving over
bumps.
Cause
On indicated affected vehicles, the noise may be caused by either or all of the following:
^
Rear trailing arm bushings
1995 through 1998 (produced up to 9/15/97) model year vehicles are equipped with a one-piece trailing arm bushing which may squeak. Subsequent
1998 model vehicles built between 9/15/97 and 1/21/98 are equipped with the new-style two-piece trailing arm bushing, but because of insufficient
lubricant within the two-piece bushing, these vehicles may also exhibit the squeaking or rubbing noise.
^
Rear shock insulator (upper bracket assembly)
On 1997 and 1998 model year vehicles produced before 1/27/98, a light knocking or tapping noise may be coming from the rear shock insulator
(upper bracket assembly). An improved rear shock insulator is now available to correct this condition. The new parts have a raised or embossed area
on the bracket flange at 90° angles to the mounting studs.
NOTE:
Bushings and collars should also be replaced along with the insulator bracket.
